Humberto Posted October 17 Report Share Posted October 17 Hello to everyone here. I am a 22 year old aspiring woodworker. I recently quit my job to start working at a cabinet and custom furniture company to learn more about this industry and woodworking hands on since I don't make enough money to buy lumber to make furniture, that is why I decided to work with masters at this in a real workshop. The owner of the shop was nice and he gave me a shot to work there even though I have no experience, so I want to be more than ready for my first day at the workshop and be as efficient as possible. What is some fundamental daily math skills I need to re-study in order to be a useful team member at the workshop? the owner asked me if I'm good at math so I want to study but don't know what he meant exactly, what do I need to know. thank you all in advance to take the time to read this! 1 Quote Link to comment Share on other sites More sharing options...
Popular Post Ron Swanson Jr. Posted October 17 Popular Post Report Share Posted October 17 What a great opportunity you have! Are you in the US? I ask that question because most of the rest of the world uses metric measurements, while the US uses imperial. So math with fractions becomes paramount. Being able to add, subtract, divide fractions is probably the math i use the most, although sometimes i will switch to metric in a project to make a math problem easier. Also, board feet. Hardwood is usually sold by the board foot - a volume measurement, and not by a linear measurement. The other thing that many of us use is the golden ratio - to try and keep proportions attractive within a project. That ratio is 1:1.61. Good luck! 3 1 Quote Link to comment Share on other sites More sharing options...
Popular Post wtnhighlander Posted October 17 Popular Post Report Share Posted October 17 Also consider basic geometry. Most joints in furniture and cabinetry involve 90 degree angles, but there are numerous situations where the ability to determine cuts needed to form other angles is important. 3 1 Quote Link to comment Share on other sites More sharing options...
Mark J Posted October 17 Report Share Posted October 17 I agree with the comments above. If you use imperial measurements (feet & inches), then knowing how to add, subtract, multiply, and divide fractions is important. 1 1 Quote Link to comment Share on other sites More sharing options...
Popular Post BillyJack Posted October 17 Popular Post Report Share Posted October 17 You need to learn your measuring tape. You need to understand an inch and how it breaks down. Cabinetry is pretty basic. Understanding cabinetry will come in time. Furniture on the other hand changes every piece. Do not get confused…. Entertainment centers are not furniture.. fastened bookcases, etc… 3 1 Quote Link to comment Share on other sites More sharing options...
Popular Post Dave H Posted October 17 Popular Post Report Share Posted October 17 When I started doing construction work (carpentry) I realized I should have paid more attention in math....you know "when will we ever need to know this" well it was almost immediately. So I went to a used book store in town and bought algebra, geometry, general math reference books and, set down and read these book so I could figure out things like the volume of a cylinders ( geometry ). Laying out a building and, needing to find the cross square measurement of a building, or how find the length of a rafter (algebra). I still use these reference books as I need them. Now there is google or YouTube, but math I found was my weakest part of my job description, so I did what I should have done when I was in school instead of trying to take the path of least resistance. Pay attention how other tradesmen attack a task, ask about the tricks that they use to expediate the task and remember these tricks. Good luck 3 Quote Link to comment Share on other sites More sharing options...
BillyJack Posted October 17 Report Share Posted October 17 Furniture math insist that complicated. For cabinetry its break downs. Furniture is about complicated joinery and execution. In fiurniture there are no nail guns or wood putty. Cabinetry is all about woodputty and nail/staple guns. Furniture is about time frames just like cabinetry.Your on it 8+ hours a day till complete. 1 1 Quote Link to comment Share on other sites More sharing options...
Von Posted October 17 Report Share Posted October 17 Plus 1 to everything above. Also realize that all lumber sizes are nominal - a 2x4" isn't actually 2 inches by 4 inches, 3/4" plywood is almost never 3/4" of an inch, etc. - and don't assume any corners are 90 degrees or edges are straight unless you made them so. 1 1 Quote Link to comment Share on other sites More sharing options...

Yes, I live in FL, US I'll practice arithmetic with fractions then and calculating volume. Thank you so much for your recommendation. 1 Quote Link to comment Share on other sites More sharing options...

I couldn't figure out how to cut an angle for the legs of a bench I was doing and felt really dumb. Now I know I just got to go down to basics and trigonometry. Thank you for the suggestion.

Books are definitely more detailed in math than youtube videos for sure. Would you mind naming the books you got? I will pay attention to the masters there every single move they take I'll ask questions for everything, thank you Dave. 1 Quote Link to comment Share on other sites More sharing options...
Popular Post wtnhighlander Posted October 18 Popular Post Report Share Posted October 18 I give these books a strong recommendation: By Hand and Eye, By Hound & Eye, and From Truths to Tools. These works explain a great deal of practical geometric concepts (in easy language), as well as touching on furniture proprtions and designing to fit the human form. If you are lucky, your local library will have them. 3 Quote Link to comment Share on other sites More sharing options...
Coop Posted October 18 Report Share Posted October 18 Good on you for doing your homework. Being an employer, I’ve found that many new hires just want a spot on someone’s payroll without taking the initiative to learn the trade. Good luck! 2 Quote Link to comment Share on other sites More sharing options...
legenddc Posted October 18 Report Share Posted October 18 There's an app called FractionsCalculatorPlus that lets you add fractions without converting it to decimals. Not something you want to have to use every time, but good to double check as you're learning. 1 Quote Link to comment Share on other sites More sharing options...
Mark J Posted October 18 Report Share Posted October 18 @Humberto, What type of furniture does the company make? Do they use an assembly line like process, or are items more "one off"? 1 Quote Link to comment Share on other sites More sharing options...
BillyJack Posted October 18 Report Share Posted October 18 When I was in high school taking wood shop, I think I found three books in the library about woodworking. Today you can sometimes have a good library that will also have woodworking magazines available. Worth a Saturday to check out. Most shop don’t want you trying to learn other shops practices. They want you to learn hands on doing their projects and their way., I tried to get a job at a shop called Sni- Valley cabinets. The owner told me you have experience and I like that , but I don’t care how the other shops build cabinetry, how they payed or the equipment they used. “We don’t care” . He didn’t care about other shops or how they operated. I didn’t go to work for them , but later heard after 25 years of business, the cocaine caught up the owners owner and wife and eventually went under.. 1 1 Quote Link to comment Share on other sites More sharing options...
Popular Post gee-dub Posted October 18 Popular Post Report Share Posted October 18 One thing I might mention is that your employer's version of how things are to be done is always correct . The person paying you is the one setting the direction. You do not want to be the new guy trying to tell the place you are working what they are doing wrong. If they call a 22 inch lower a "550" then that's what it is. Kitchen and bath have been metric for a long time. If that is the type of stuff they are making get used to that. If they are making custom furniture in the US then get used to the fact the 1/2" is 1/32" larger than 15/32". Don't stress; you'll do fine. Just be open to how things are done at your new employer's biz and adapt to that. I made a 40 year career out of adapting to how other people did things regardless of how much "smarter" I thought I was 3 1 Quote Link to comment Share on other sites More sharing options...
BillyJack Posted October 18 Report Share Posted October 18 Most shops are open to better options. Saving money and time is #1 priority. You have a lot of shop guys just simply waiting on the next guy. If you have solutions , only a fool won’t hear you out.. 1 1 Quote Link to comment Share on other sites More sharing options...

I wanted more than a spot I wanted an opportunity and I won’t let Dan (the owner) down. I’m practicing arithmetic with fractions to have a better flow at the shop and not take so long trying to figure out simple calculations. thank you for your words Coop!! 2 Quote Link to comment Share on other sites More sharing options...

Do they use an assembly line like process, or are items more "one off"? The main thing Is built in cabinetry and also custom furniture pieces. I know they do drawers in an assembly line like with a dovetail machine that’s by computer I believe. Quote Link to comment Share on other sites More sharing options...

Since I was in college Kitchen and Bath cabinetry have all been spec’d in millimeters in my localized experience. People I’ve worked with call it the 5 mm, 32 mm, or system 32 method. Is this another one of those weird California things that I thought was national??? wouldn’t be the first time I’ve stepped in it… :-) 1 Quote Link to comment Share on other sites More sharing options...
