Re: Small things can be cut easy without tabs

Ok, the technique I saw somewhere was that the small pieces were profiled in solid stock but stopping short of cutting through, and then they resaw slices on the bandsaw and the pieces just fall out. Seems you can cut several copies out of a thicker piece of wood that way. I have yet to try it but i...

Re: Vacuum Hold Down for Repetitive Shapes

You can do it out of one piece - much simpler in cutting - but you pay for it in having to drill a line to each piece and the extra hardware. It may be easier on smaller jigs to do this method: https://www.youtube.com/watch?v=ryJ56ESAHZQ The caveat to this is that you have to have a straight, relati...

Re: Mr M's Woodshop

No problem Dave.

I didn't want to inundate this post with my stuff, so I started a new thread:

Re: Vacuum Hold Down for Repetitive Shapes

So, some more info/improvements for next time: * All we had on hand when I did this was an oiled rotary vane vacuum (5 CFM) we use to de-gas urethanes and silicones. These work great for THAT and anything else you are at full vacuum fairly quickly. It holds the parts brilliantly, but with the leakag...

Re: Vacuum Hold Down for Repetitive Shapes

Here is a shot fully assembled and cutting a sheet. I used locator pins to assure the same placement every time, and the file is written from absolute 0,0, so it's just load, Z and go. As you can see, these were some interesting parts to direct vacuum to, so I used 1/8x1/4 in-board gasket from AllSt...

Re: Vacuum Hold Down for Repetitive Shapes

So with that working, then came the real challenge, a 4" and up to 3/8" thick polycarbonate disc with 7 holes to route around. Very little area to pull vacuum. So this time we used HDPE. I cut the plenum and the channel in the lower half. In the channel is rubber X-gasket available from Mc...
