  1. Hi Everyone, Imagine someone saying I bought a drill to see how good it was and well... It's not great. It would be interesting to know which 3D printer you're talking about, and the year too. How many prints did you do in total with it ? I would say the same to Chestnut about design theft, is this a fair argument ? Many people do tools copy out of wood, and nobody is yelling for thievery. There's several designs for the same purpose. You should be aware you can't get a genuine Kerfmaker in Europe. On the other hand, the printed version is a fraction of the price and works perfectly, so... As you can see, it's not exactly the same operation than the genuine Kerfmaker. Too small to embed the Allen key, so I put some magnets. These are for giveaways to friends. I did not show them because I did not released it on Thingiverse, and I'm not here to promote my designs, I've got a day job all I do is free and copyleft, so... You say the cam clamps are easy to make from MDF. Are you talking about any design theft ? Figuring out the right gap, the right angles and the right offset will take you a bit of time and several prototypes for sure. MDF will explode under pressure. Aluminum will jam quickly because of higher friction... Maybe you can try out of hardwood, but the 3 sides holder will have some trouble with a probable split point along the grain. I'm afraid the printed tool is the best option here : low friction cam, you download it and you print perfect fit clamps. Download and slicing time = maybe a minute ? Time and price is pretty hard to beat. Come on, this is pure supposition. I suspect... you're not totally objective Well, that's a point of view. I'm a huge fan of open source and copyleft, which free people to start from a design or a technology and raise it a step further. As example, the Filament 3D printing technology was locked in copyright since the 50s, with few inovations by the way. Nobody could afford a 3D printer during the patent's lifetime. As the patent expires in 2005, the Reprap project opened that technology to the world, with innovations by numbers. Actually, you can get a proper 3D printer for under $200 because of open source hardware. You can have 3D printers in schools! Now Stratasys which owned the patent for 50 years copy some of the Reprap innovations in his printers. Anyone can make his own opinion about what is the better for the community. Remember copying for personal use was always allowed. But open source is much about original designs that are copyleft. Actually you can find anything open source. But you can still pay a company if it's valuable to you. You're absolutely right. On the other hand, you're still in hybrid mode as you consider using the digital method for jig or helpers while you could already make the whole part digitally. Now the benefits depends of your own appreciation. Some people will say than a 3D milled part would be a single piece with continuous grain, so better looking than lamination. And others will prefer using less good wood, even if the jig/helpers are wasted materials. There's choice to make on the method, but also during the design time. Digital fabrication force to upstream work. The waste of good wood is a real subject. We all consider the huge amount of chips wasted during planing. Actually I note less waste with full CNC machining: you surface just where it's necessary, and you can machine twisted or bowed boards. Especially when you do 3D milling, as both sides will be machined. 3D printing is different, but you can have some waste too. Especially if your design need support material. Once again, you want to adjust your design to reduce waste. In my workflow, CAD design takes less time than the sketches on paper. I go in front of the computer when most of the project is developed except dimensions. I start from CAD program only when gears or something mechanical is present. I found you save a lot of time thinking about your project several days or week before to lay something on the computer. Surprisingly, my main digital fabrication tool is my sketchbook. These machine have no brain for sure. You want to use your own. CNC machines needs to be guarded by an operator, just in case. The most important: preventive maintenance is the best you can do for your machines. One quick review per month is worthy. After 15 years of CNC, I can say as long as you treat your machines well, there's not much to fear. You're the main reason of issues. 3D printers are actually safe and pretty reliable. I evaluate my 3D printing farm issues maybe lower than 3%, including my mistakes which represents 60% of the issues. My 3D printers works about 60 hours per week each. You don't take a lot of risks to be away from a 3D printer. Definitely. Early issues are mostly fixed nowadays. Clogged nozzles comes mostly from cheap and dirty filament, which is avoidable. If you left your printer heating the air for hours, the probable clog is your mistake. Tangled filament is also your mistake. There's no way to produce a tangled filament. Broken bits comes from unappropriated feed and speed, once again, the operator's mistake. As you can see, the mistake are mostly done prior to hit the play button. Most of the time I'm in the shop while the machines work, but doing something else : cleaning, design, assembly or finishing. Only the newbie spend his time the eye screwed to the tool head (which is hypnotic in a way). I respect your point of view. You're right, owning a CNC is a personnal choice. I won't recommend to get one if you're not a hi-tech guy. About the "ugly noodle look", the best I can do is to show you some examples : I don't know if this kind of prints matches your personal taste, but maybe we would both agree ugly is not the appropriate word ? Please note both are rough. The bust just received a layer of primer. I recommend the 3D wasp project from Italia : https://www.youtube.com/user/wasprojecteam Their last project is an adobe bungalow made with the raw materials found on location. Pretty interesting. There's a lot of interesting comments above. I'll try to reply soon See you then.
  2. 5 woodworking stuff that are worth 3D printing. I would like to point out few things. The 3D printing time is not a hard fact. It must be compared to the transportation to and from the specialized store, or the online store shipping time. Please note the 3D printing time is not time consuming unlike building a jig/tool by yourself. Usually, the 3D printed stuff I need for my build is printed during the previous night or during other manual tasks like rough cuts or so. The overall precision of a standard 3D printer is <0.01" I did not spent much time looking forward to the best examples, but just valid ones. Printing time calculation is based on one of my average 3D printers. Make your own opinion. 1.

  3. Thank you Chet, this is fair, and greatly appreciated. I edited the title and wrote few introduction words.
  4. I understand, no problem. Any advice to context the topic is welcome.
  5. Ok, I'm in the wrong forum area, I got it. I'm really sorry. Maybe a moderator will be kind enough to move this topic to the right place ? Do you think it's necessary to edit my first message to bring some light on the topic ? Something like "in friday live september 6th 2019, from 40'09" Marc said various things about CNC and 3D printing which are based on non CNC user commonplaces. This (I wish) friendly topic is an attempt to give people a window into the true essence of digital fabrication, from the CNC owner side, and a way to share opinions about CNC in general." Would it be appropriated ?
  6. Sorry guys if the topic is of no interest for both of you. In his friday live, Marc challenged to make him change his mind about 3D printing. This is an friendly attempt. Thanks for your reply Chestnut, I don't try to convince you, I have no problem with different opinions. I just enlight what is misleading. To be valid, an argument needs to be true whatever the angle or the people. As people share their opinions, this is always rich conversations, and I believe we both understand each other. I hope my English does not sounds to drastic or rude to anybody, because that's not what I want to say at all. I wonder if the title of this topic does not seems too aggressive. If it does, I appologize, that's not intentional. I just try to be understandable with precise words, because it's the way frenchies do. Dogs don't make cats... The topic was mostly about 3D printing and it strays a bit to CNC routing. Never mind, it's wouldtalkonline, right ? I understood mostly all of you said, even if I had to do a little documentation about "stubborn curmudgeons". You have a personal taste perfectly defined, and there's nothing much to say about that except it's fine. That can't be discussed because everyone have its own taste. You value cratftmanship which is highly valuable, for sure. I do too, even if it's not the same way. We'll talk about that later. Taste or value is not the angle of my argumentation. Neither the learning argument or the money argument. We need to leave all that apart because there's no relationship with the technology. There's expensive pannel saws, precious hand planes and even small stack of systainers that cost much more than a capable CNC router. Any technique can be teached and learned, even about machines. Value and taste are highly subjective. Some will value design, others aged stuff, others materials, it's just a question of taste, of personal values. It's subject to mistakes too. According to your taste, you can find a piece marvelous at first sight and the second later loose any interest about it since you noticed it's not crafted as you wish. For somebody else, the perception will be the opposite. Taste, value, learning, money are not valid arguments to talk about a technology. Your last message contains a lot of presuppositions usually said against technology. I don't blame you, it's pretty common, and this is not related to CNC, as you can find the same arguments translated about other technologies. My gran pa hated power tools and used the same arguments you use about CNC. You can do a poor job or a marvelous job with any technology. Definitely. Doing by hand does not guarantee to do a quality or an emotional piece. A masterpiece requires first a good idea, second a perfect realization. The tool used does not matter. If the masterpiece is perfectly executed, you can't guess which tool is used. The tool is the way to get from your idea to the piece. As you master the tool used, it does not matter if it's a hand tool, a power tool or a CNC tool. CNC have a lot of superpowers, like repeatability and precision. This is great if you have to produce by numbers, but CNC is not related about mass production, it's just a workflow. Like any tool, you use it the way you need. You can make your living turning furniture feets by hand, and make them by numbers. I believe, the woodturner's soul should dilute since the first pieces. I do not produce similar pieces very often. Most of the time, I've got an idea I want to materialize. I do a bunch of prototypes before getting what I want. That leads us to the "time in front of the computer" argument. You're right, you need to spend some time in front of a screen to prepare the CNC machining. I was not born under a CNC. I've made my first furniture piece in 1984. Before CNC was invented, we still needed some time to design a piece and make plans. Even for my CNC production, I spend a good amount of time just sketching. Actually, you can find a lot of woodworkers, like our host, designing with sketchup, even if they don't own a CNC. To me, sketching, then assemble on sketchup, then print some BOM/plans, then making some templates, then do hybrid woodworking, is circuitous. You would probably agree it's more efficient to sketch ideas, then CAD the best one, then machine on CNC. As long as you master the computer tool, CAD/ is not the longest part. The creative process is by far the longest, in my riding. About Marc, I'm an early follower, I like his style, I like his speeches, his sense of humor and even if the old man I am don't have much to learn about woodworking, his videos are always inspiring. I'm highly thankful for that. He always reply with patience, and have an overall good attitude. I hope the title does not sounds too hard, this is not what I wanted to do. This topic is definitely not to blame or to complain. I wish there's no misunderstanding about this. I just felt uncomfortable hearing Marc with a partial vision of that technology. In what Marc said there's some presuppositions that are not totally true about 3D printing. I don't blame him, he's not a user/owner, he only have a distant appreciation of the essence of 3D printing. I just wanted to bring a different point of view, from someone which is a long time builder/owner/user of these technologies. I wish this give people a window into digital tools. Including Marc, because I appreciate him without knowing him. Actually, CNC in general and 3D printing is pretty mature. You can't find a better time to try those technologies, if you're a tech guy of course. To end this too long reply, I agree with you about poor examples of CNC use. The technology is much mature thant CNC users themselves. Most of CNC owners uses CNC to feel capable to do things they're not skilled enough to to another way. That's an argument about CNC, which makes things easy in a way. That's why you saw screaming machine made stuff. Actually, there's simple designs perfectly executed by CNC, but the technology used is not obvious. There's also obvious CNC machined pieces that are interesting indeed. All depends of the talent and the skill of the guy behind the tool, handtool, powertool or CNC. I'm not sure to be right on a CNC or not CNC survey : Not CNC CNC Not CNC, and CNC below :
  7. Hi everyone, I really don't know. But I got it by mail, you said "This is an incredibly loooong post complaining about what somebody said on the internet. im not reading all (any) of that. Good day." Feel free to read or not. No problem Chris. As you did not read, you could not notice this is not a complain about what somebody said on the internet at all, even if Marc is not anybody, but a respected opinion leader. Long story (reading) short: It's just about dissemination of clichés by people who are not aware about CNC, and have a false opinion. No complain, how can they know ? Because I'm an experienced CNC owner, I share the essence of these technologies which differs a lot from clichés. And I had to be precise for people to eventually understand, that's the difference between explanations and complains. I whish you could learn some things. Maybe If my English was better, I could make it shorter ? I'm afraid I did not made myself fully understandable. Sorry about that. It's not about validity of CNC tools, it just to bust clichés which are not true about computer controlled technologies, including 3D printing. It's not about you should or should not use them, but about understanding the differences between hybrid woodworking and CNC workflow which differs a lot. If you're a hybrid woodworker you don't have the keys to understand the CNC workflow. Even if CNC routing is substractive manufacturing too, the CNC workflow makes most of other tools useless. With a CNC, you don't even need a flat surface at startup, because you can machine both sides. Most of CNC users on Youtube or magazines includes CNC into their hybrid woodworking workflow, including Frank Howarth, which is using only a small percentage of CNC (super)power(s). It's doing with CNC what you allready do with non CNC tools. That's where people do not totally get it, and that's exactly your CNC as engraver example. Please note than 3D printing, as a full versatile mini factory goes one huge step further. I understand your last argument about satisfaction to do it by hand, I considered that in my first post. This is the only valid argument against CNC workflow : what you like or enjoy doing. And this is out of clichés, it's anyone's own preferences. My quote is about the actual CNC workflow essence, not if it's valid to use it for you or not. I agree Chestnut, its about liking or disliking the technology, the only valid argument, as said above. About unique/replicas production, that's not a valid argument as you can do unique things on a CNC, of course. About the speed, well, as I said in my first post, not everything's worth to be made with CNC technology. Based on my experience with CNC workflow, I can make on a week end projects that took me several weeks with a hybrid woodworking workflow. I'm afraid that's, on average situations, substantially a much faster process. Exceptions are related to very simple parts, like a block of wood. As complexity grows, like curves or tricky joinery, CNC takes quickly advantages. A common mistake is people basing their opinion from hobby machines, like the x-carve, which is not a very capable machine. A serious CNC router which take 2" passes at 800in.mn is definitely not beatable by traditional ways, even for simple parts. Should you get a CNC router when you'll be retired from computer day job work ? Well, you're the guy to answer this question. To me, it's probably not a good idea if you stay into a hybrid woodworking workflow, because the CNC would just catch dust in a corner of the shop most of the time. But if you're aware and ready to organize your workflow around CNC machines, it's probably the best idea actually. I had to sell most of my powertools and my workshop is pretty different actually and surprisingly clean. Yep : definitely the only valid argument is what people personally like or dislike.
  8. This thread is started in reply to Marc TWW Friday Live's "change my mind" challenge (40' to 49'). Like hand tools people have narrow ideas about power tools, people who are not aware about digital fabrications says a lot falsehoods by misunderstanding. This is a friendly attempt to give people a window open to the essence of digital fabrication in general. This is not any personal opinion, just facts. What Marc said during the live makes me jump out of my chair. Sorry Marc, I don't want him to stop making videos, indeed, and I hope he was just kidding. But I'm afraid Marc's definitely wrong. And I will show why. I don't blame Marc because he's an appreciated woodworking expert, and nobody can perform in every subject. I took time to see what I missed from the start of the 3D printing argumentation to be sure to answer right. According to the average knowledge, we have a long way to go, sorry. I want to say I thought exactly like Marc until I get my first 3D printer, even if I was an early CNC router enthusiast. I could not imagine how wrong I was. My thought, was fulfilled with a lot of presuppositions : - Plastic is cheap, fragile and ugly - 3D printers are expensive tools just able to print cubic and ugly nuclear green picatchus - 3D printing takes weeks to print too small parts Shamefully, I did not understood the genius of 3D printing by the past. 1. Understand 3D printing paradox. That's the start point why 3D printing detractors are wrong. That's mostly because a lot of 3D printers owners prints stupid things with it. Please read carefully because this is the major point. There's a 3D paradox theory which is curiously known since the seventies: 3D printing has a range of utilization which is unbeatable by any other production process, definitely. Out of this range, other methods outperform the 3D printing. Easy isn’t it ? Here is the 3D printing paradox: what takes time, is expensive to do, needs a lot of different tools, need a lot of skills, with traditional methods (substractive fabrication), is highly interesting to be done by additive fabrication: simpler, faster, cheaper, etc. On the oposite, what's simple to be done with substractive manufacturing is a no sense to be done by additive manufacturing. Examples : A control pannel is just a flat material with holes. You can't beat substractive manufacturing. As Marc said, this is too fast to be done with a drill and a jigsaw. On the opposite, captive concentric bowls are extremely difficult to be done, even for a skilled wood-turner, while its child's play to be 3D printed. If you need to make a very technical part, a complex organic shape, precise mecanical interactions, complex assembly, embedded shapes : you can spend years and a lot of money to do it with traditional ways. Some can’t be done by any other methods anyways. Don’t waste your time, print it in few hours. First superpower of 3D printing : it makes impossible or complex parts easy. 2. A totally new paradigm We all learned in school there’s one way for the world to go : growth & trade. Could this be wrong ? Trade works because you get in shops what you cannot make yourself, right ? The woodworker is skilled enough to make is own furniture. The furniture shop is useless for him. What if you don’t need any skill to make stuff ? Well, any shop should be useless then. Actually, you can find anything mostly 3D printable on sharing websites like thingiverse.com : Download it, print it, done. My experience : since I get my first 3D printer I did not buy much hardware as I did by the past. 5 to 10 % must be the absolute maximum. Most of my tool accessories are now 3D printed, and some of my tools too, like my router lift. I do not really need to find in a shop an exotic metric to imperial hose adapter, I just have to design my own and print it. Why would I spend hours sourcing it, then days to recieve it, when I can design and print mine in few hours, for a small percentage of the price ? You got it : when you own a 3D printer, you get a personal factory in a box, simple as that. Of course, you can’t print everything (at least in 2019), and everything is not worth printing anyways. But make no mistake : most can be 3D printed, even unexpected ones like fully working pumps or electric motors. So the fact is : as long as you don’t mostly need shops and you can produce mostly anything by yourself with no skills, all we still learn to our students about growth & trade is questionable. As 3D printed parts are mostly free and/or open source and/or for personal use, patent protection is no more the rule. Anyone can share a better alternative of a $99.99 Festool accessory you can print for pennies. And yes, as there’s a measurable growing impact on sales, major companies consider this pretty seriously. Millions of 3D printers are sold every year. Some of mine works 60 hours per week since 2013 (I’m a late owner). Second superpower of 3D printing : Autonomy Third superpower of 3D printing : Open Source 3. Buy for the garbage During your life, how many tools or objects did you throw away because you broke or loose a necessary part of it, hm ? In my riding, a lot ! Sometimes recent objects, by the way. Manufacturers have no interest in lasting products. They provide spare parts for some times or not at all. Duct tape lovers can fix stuff sometimes. Most of us have already spent hours to try to fix out things with hazardous craft parts. Well, your personal 3D mini factory can produce strong and good looking spare parts. You can design the genuine part with a twist to fix the known issue. Actually, the list of my long lasting fixed parts increase as time goes by. I’m able to repair more frequently than by the past. That’s financially attractive indeed, and good for the planet. That’s the fourth superpower of 3D printing : planned obsolescence killer 4. Presuppositions about 3D printing and CNC fabrication in general that are wrong. A. 3D printers are small volume, so it’s useless. The two presuppositions are wrong. Entry 3D printers have a small build volume that’s true, but there’s 3D printers able to build family homes, it it big enough ? Then gentlemen, size does not matter at all. Definitely. Uh, at least for CNC. People need to understand what is CNC production. Another superpower of CNC is repeatability : you can produce perfectly matching parts even decades later. Smaller machines are more productive than big ones for many reasons : first, they can work simultaneously, like a multiple core computer, so you get the result faster. That’s why I own a small farm of small 3D printers. Second, a bunch of 3D printers is much versatile on production. You can spare various parts on various printers, or a portion of a big part on most of the printers. A single man can manage a lot of CNC machines, while he can only work one power tool at a time. Different processes, different rules. Last, a bunch of small machines are less expensive than a big one. B. About CNC machines producing templates. Sorry for the hurt, but this is the most stupid idea ever ! This is a huge misunderstanding of CNC workflow. Once and for all, CNC is just about no more template ever. As long as you have a CNC, why would you need any template ? Remember the repeatability superpower : make directly your part on the CNC. Once again, different processes, different rules. Don’t think power tool process with CNC machining. Think directly in CNC mode. When you think into a CNC workflow, you make ready to assembly parts in once. You focus on design, assembly and finishing. The CNC manage to produce a perfect part better than you can do afler years of skill training. OK, we take apart the joy of doing by yourself, that’s another subject. If you want to manufacture the part by yourself, don’t get a CNC, and also sell away your power tools, simple as that. It’s not the subject at all, each one finds the way to enjoy making : hand tools, power tools, hybrid or computer controlled. Making templates with a CNC is like marking dovetail prior to use a leith jig : a full waste of time. C. About plastic, issues and 3D printing quality. The wood is obviously a much noble material than plastic. I guess we’re all wood lovers here. That’s two different things, each brilliant at different purpose. But make no mistake about it, like any materials, plastic is unbeatable for a bunch of applications, like wood is, like steel or stone are. Robust transparent parts needs to be done in plastic. There’s actually a lot of various 3D printing materials with their own perks, from flexible to insulating or conductive properties. Thermoplastics are inexpensive, and if managed properly can be recycled to make new parts or new filament to make new parts. So is plastic a valuable material ? Well, absolutely, as long as there’s perks to use it instead of another material. You have probably seen ugly 3D prints from cheap Chinese kits (mostly useless trinkets). Cheap Chinese kits was well known about endless issues. Well, with all due respect to its detractors, this is no more the case. Actually you can get an assembled 3D printer which makes perfect parts just out of the box, for about $150 (the Creality Ender3, is actually a good example). You won’t spend any time in fixing or understanding no more. The 3D printing market is very mature nowadays with performing 3D printers at reasonable price. 5. About skills, soul, tradition and fine craftmanship A frequent argument against CNC manufacturing is the machine do for you, so you don’t learn, you have no fun, you loose knowledge and tradition, and last, the final product have no soul. Sounds like the ultimate words have been said, aren’t they ? Well, I have no choice than to reply point by point. A full 3D printer user need other skills, nore related to design and engineering, so like woodworking, there’s different levels in woodworking. Believe me or not, as I’m a CNC owner for over 15 years, I can say that the beginer who have no understanding of wood grain should expect to live nightmares with his first cuts. If you don’t understand wood, feed and speed, the CNC will be no help at all. CNC joinery requires to be aware of traditional techniques, and brings you to another level too, where you can program no glue hidden snap in joinery or complex tenoning which are comparable to japanese joinery. Tradition is another subject, as you can make period replicas on CNC machines. So what about soul ? Well, to me the soul of a masterpiece is not based on technology but into intention. Technically you can make a very complex fine machining mostly impossible for the hand of a master, with no soul in it, or a very simple machining with true visual emotion in the masterpiece. The soul is brought by the creator, not by the tool. Some creators have a linear experiencing process, but this is still not related to technology. All these arguments can be true if you’re not a technology guy, but are not valid for everybody. There will be CNC master craftmen for sure. 6. Conclusion. It is now obvious that 3D printing is a pretty interesting tool to own, as long as your mind is open enough to technology, of course. It’s much about your personal taste than about the interest of the technology. The die is cast. Almost all of the 3d printers owners did not go back. 3D printing have the potential to make substancial changes to your life and your workflow. If you’re able to exploit the technology, your 3D printer will be one of your most used tool. Definitely. CNC manufacturing in general is a relatively new technology. It requires to completely change our habits in the workshop, from the workflow to the joinery. A lot of people are not ready for a paradigm change, and who can blame them for that ? But almost all of their arguments are not valid, except the want or need ones. Marc, if you read this and I managed to enlarge your appreciation of 3D printing, please keep on with the videos
  9. Hey @Mark J, well sometimes you'd rather be in front of your workbench.
  10. Hi there ! You guys are arguing about insert strength which does not really matter in frequent uses. Floating tenons, dowels, pocket holes, biscuits... have different strength for sure. BUT, as long as you use a modern wood glue, especially long grain on long grain, event without any alignment/reinforcement, the glue should be stronger than the wood itself. Obviously you can experience good results with any jointing system as long as the wood grain is properly oriented. End-grain is another story. Only long grain brings strength to a joint. So you want at least dowels or floating tenons. Biscuits or pocket screws would be weak in this situation. Biscuits are fine with modern glue and long grain applications. You want to consider traditional joinery, engineered when glues was not as good as today's. Ask yourself if the joint can be strong enough with a rabbit skin glue or so. You would not use biscuits without a proper glue, while dowels and floating tenons can hold only with friction. QED...
  11. Domino machines are much better than the Triton. The TDJ600 works but it's not a great tool.
  12. Hi there, In France we have a saying : (don't trust) the man who saw the man who saw the beast. I own a TDJ600. This is not the best quality ever, (what would you expect for the price tag ?) but mine works fine. I mean the holes are drilled in the right place, and joints are flawless, dowels are hold tight. Some precautions by the way : I check the fences with measuring tools and I don't trust the graduations. You really need to push hard to dig into the wood. It's not about poor quality bits, but about the spring which is ways too strong ! This is a sign of poor engineering. You really need a strong workbench to hold the pieces while pushing. (maybe 60 pounds of pressure ?) This is definitely not a woman friendly tool ! The foundry parts are barely deburred. The tool is functional, just comfortable enough to be hold. This is not like a Domino you can set then drill with confidence. With the Triton you need some test parts. But once the set up is done, you can work pretty quick. I probably drilled thousands of holes within a year with no issue. I would expect the spring had released a bit but nope, the machine works as new. I really need a proper spring. Note: the bits are compatible with Mafell's (+-20 bucks per set) so you can have 6mm ones. With Triton, the quality is not constant. Some tools are great, like the TRA001, some are just acceptable. The TDJ600 stands in between. Some comes directly from China manufacturer's general catalog, like the oscillating drum sander or the super jaws. You can't buy with confidence, get some owners advices first. I saw the video Mafell vs Triton. Well, to me this video smells like scam. First, is comparison between the best Cadillac versus a first price car fair ? Probably not. You need to compare things with the same price range. Unless you want to deliberately kill the cheapest's reputation or magnify the best. Second, before drilling the first hole the guys is already dismantling the Triton. So strange isn't it ? Who would do that in real life ? So we don't know if the problems comes from the Triton or from the guy's early "repairs". Let's be objective: after more than a year using mine, none of his 5mn judgments matches my experience. Some of my friends bought a TDJ600 after testing mine, with comparable experience. I know the Mafell which is obviously a great tool, ways better, at first sight you know it. There's a small chance he get the worst TDJ600 on earth. Maybe...
  13. In Europe a simple doweling jig have a great success, the Joint Genie. It's easy to make your own out of scrap wood if you're accurate enough. But I guess any jig from Rockler or whatever will do the trick. You can make your dowels from your Maple stock scraps, but Beech, Oak, Ash, Mahogany can work too. Please refer to a wood hardness chart to find species with a close hardness. Just avoid sap wood for dowels. Glue acts as a lubricant, so the same diameter, hole and dowel, is perfect.
  14. On the drawings the double tenons are too thick IMHO and the area in between the two tenons is too thin. Multiple tenons just allow a larger gluing surface, but are not stronger. Do you really need a larger gluing area ? Well, except oily woods or questionable glue type, you would probably not. The main thing to consider is the proportion mortise/tenon compared to your stock dimensions. Do a simple math : take your stock width, divide it by 3 and you'll get almost the good mortise/tenon size. (works both width and height). I agree with @gee-dub, I would use dowels on this kind of project. I usually use loose tenons or dowels, because you waste less stock. I was always disappointed by the amount of wasted wood removed from the stocks. When you use floating tenons or dowels, the needed stock is shorter and you minimize waste. The tenons and dowels can be made out scrap wood, whatever the size. I use real tenons only when pull dowels are needed. Choosing the right dowel is easy : you need at least the equivalent of the dowel diameter all over the dowel (the 1/3 rule again...). The more dowels you can put, the stronger. You can multiply dowels using staggered arrangement. The dowel or floating tenon hardness should be equivalent to the wood hardness. Sometime I see people using beech Dominos in pine projects : poor joints I'm afraid...
  15. I try to recycle by myself most of the time. You can get a very strong material out of Styrofoam which can be polished to high gloss. Get a small bowl, and pour some acetone into it. The acetone will dissolve the Styrofoam, releasing the air embed inside. This way, large Styrofoam packaging can dissolve into a small "ball" of polystyrene. You can roughly make anything out of this "ball" : shaping it, wrapping it around tools to make scabbards or handles, you can pour it into a mold, make some boards or blocks you can machine later. I made furniture feet out of melded Styrofoam just by pouring it into small containers. I made quick storage furniture out of cardboard in the early 2000's years. Surprisingly it was very strong and really last. So I designed quality cardboard furniture for house or theater purpose. Here's some samples : Since, I always keep some cardboard sheets in the shop. You can fill torsion boxes with cardboard for extra strength or sound insulation purpose. Cardboard can make a good core material for composites too. It cost nothing and is really useful. All valuable materials in my opinion.
