  1. When I first got into the business (50 years ago) it was CADD - Computer Aided Design and Drafting. The original companies in the field were startups such as Calma, Computervision and Gerber Scientific. The technology was basically built around digitizers connected to CRT's to provide an interactive environment. Some of the larger companies such as IBM and Control Data had internal development programs using large interactive CRT's, but the small startup companies ruled the roost. The equipment was applied to a variety of disciplines such as Electrical Schematic Drafting, Printed Circuit
  2. This is one of those times when I'd put on my humble hat and admit that there are others more skilled in solving this type of problem. Send him to a pro and go back to making sawdust.
  3. I've tried the jointer method and it worked well, especially since I didn't need a cleanup pass, just sanding. I prefer the TS method since it is faster and doesn't produce a ton of chips. I also appreciate the leftover wedges that come in handy.
  4. I gave up on CA glue for this application. I switched to epoxy and haven't had a problem since. It takes longer to harden, but so does throwing a blank away because the tube broke loose.
  5. These would be great in the woods when harvesting. The trees won't see you coming ! ! !
  6. I have a home made vacuum chucking system. I use three chucks for a variety of applications. 1. A 14" diameter flat chuck made from two layers of BB plywood covered in craft foam. I use this any time I have a bowl or platter with a smooth rim. 2. A 4" diameter deep chuck made from a 4" to 2" PVC reducer with the edge covered in craft foam. I use this if I have a bowl or platter that does not have a rim that will seal such as natural edge or square rim. I also use this chuck if I have to mount a bowl to work on the inside. 3. A 3" diameter deep chuck made from a 3" to 2" PVC reducer. I use thi
  7. I agree that the sides of the miter will move together - but - as the wood expands or contracts across the width, the angle of the joint will change. Depending on humidity changes and type of wood, this could be significant enough to cause a problem if both legs of the joint are fixed against the walls. If one leg is a peninsula, it could be allowed to float as needed. You can figure the amount of movement and build it into the design.
  8. I have tried the cole jaws, then built a longworth chuck. Both worked well (the cole jaws were limited size). Then I built a vacuum chucking system and haven't used the mechanical jaws since.Vacuum is faster, easier and can hold natural rim bowls with ease. I bought the pump on ebay, made my own coupler and made an assortment of heads from a mixture of PVC and plywood. Total cost of the system was about $200. If you are interested, the cole jaws are for Nova chucks and the longworth fits on a 1 1/4" spindle. I'd be happy to sell either or both.
  9. I agree on using horizontal grain on all 5 pieces. Center piece glued into a shallow dado will be more than adequate. Corner joints may be a little weak if just butt joints. Some options could be mitered joints with splines, box joints or dovetails. You could even go with the Greene & Greene look.
  10. If you think that is bad, try overfilling a cyclone system with a pleated filter
  11. First of all let's agree on how the gouges are measured. A gouge can be measured across the flutes or as the diameter of the bar. Spindle gouges are typically measured as the diameter of the bar and bowl gouges across the flutes. That being said, I find that I use my 3/8 (1/2" diameter bar) with a swept back grind most frequently.
  12. Drilling freehand won't work. You can't align or space the holse with enough accuracy to look even. You need to find a way to mechanically position the block for each hole. Also, as mentioned above, drill first and glue up later. Here's how I would approach the problem. 1. Determine the center to center distance between holes and rip a scrap of mdf to that size. Cut the strip into blocks. Now you have spacers for positioning the holes side to side. 2. Rip a strip the width of the stagger pattern. This strip against a fence will give you the front to back stagger spacing. 3. Clamp a fence
  13. A sled to hold the router at the proper angle and a 1 1/4" dish cutting bit that cuts on the end. Similar to the rig that some use to flatten large panels and work benches but set at the angle (~15 degrees) to produce the chamfer. http://www.titantv.com/account/login.aspx?returnUrl=%2fdefault.aspx
  14. If you cut your dados in the sides before adding the edge banding you end up with stopped dados. Just be careful when trimming the banding. Either use a plane or use a filler with a flush trim router to bridge the gap.
  15. Whatever you do you will have to design the pivot point to be at or near the front edge of the cabinet. This translates into making the main cabinet deep enough so that the door boxes are inside the cabinet and not in front. If the outside width of the cabinet is 24", the door boxes will be about 11" wide. Deduct 1 1/2" for the thickness of the box and another inch off the corner in the center to provide swing clearance and you are left with about 8 1/2" +- of usable shelf in each door box. You would also want to use piano hinges to support the weight of the door loaded up with paint cans.
  16. Looks nice, keep it as decoration, but don't try cooking with it. 1. The steam will warp it. 2. The internal heat could ignite it 3. The heat coming up around the edges of the pan will char the rim and probably ignite it. 4. The smoke will stink up the house. There is a reason that pot lids are made of metal, tempered glass or high temp plastics.
  17. I have this saw in my shop for about 7 years and I have never had a problem. The only negative is the depth required behind the saw (I would like to place it closer to the wal)l. This has been a common problem with SCMS's until recently when the Kapex and Bosch saws hit the market. I use it mostly for crosscutting hardwood and find the accuracy excellent. Make sure you have a quality blade designed for SCMS. As I recall, I paid about $400 for my saw in 2007. I don't know the current price, but if it is in good shape, $225 sounds like a good buy
  18. I find that knots fill in better if I use a dark filler in the epoxy. My usual choices are walnut sanding dust or fine coffee grounds. If you are filling small cracks or voids in the cherry, fill the epoxy with cherry sanding dust.
  19. I've had the best results with these - http://www.leevalley.com/US/wood/page.aspx?p=32308&cat=1,180,42240,42281. They cut clean and last a long time.
  20. I know it isn't "pure" but there is no reason you can't use the narrow offcuts for the top. If you joined a couple of 2 - 2.5 inch strips to make one of the boards for the top you can save a solid board. Just use the joined board in an interior position and don't put two of them adjacent. The glue joints will be hidden and are stronger than the wood. You can even go to the extreme of making the bottom half of the board from two short pieces.
  21. I would sand to 400-600, buff with a mild abrasive such as tripoli and/or white rouge then polish with a hard wax. If this sounds like the Beall buffing system, it is.
  22. Next time, buckle the seat belt behind the tool. Cars aren't smart enough to know the belt isn't around the body.
  23. I laminated the table myself. I started with 1" MDF, cut it to size and routed the hole. I then used contact cement to glue a sheet of formica to the top and a sheet of formica backing to the bottom. I used a flush trim bit to cut the formica to match the edges of the top and the hole. I then glued the oak trim on and planed it flush with the top. Finally I rounded over the outside edges and cut the rabbet on the hole, sanded and finished with a couple of coats of wiping varnish. Masking tape kept the varnish off the formica. If you look at the third picture you can see two holes in the ap
  24. I made a few tables for my wife's sewing machines. I used the same basic design each time. In each case I used an oak base with aprons to support the legs and top and a formica covered top with oak trim around the inside edge of the cutout and outside edge of the table top. The trim around the inside of the hole is 3/4" thick oak and I used a 3/8" rabbet bit in my router to create a ledge for the insert. I made a solid insert as well as a 3/8" plexiglas top cut to fit the machine. (pic 2) I made a support shelf by adding a board parallel to the front apron and a couple of short boards
