I'm interested in adding a vaccuum hold down to my shopbot table. I'll be using a similar grid as the shopbot 4 zone part file, but modified to hold my pieces, which are small in height, but long in width.
I want to hold down a 1/4" x 5" x 96" piece of oak, so I can cut parts out of it with an upcut spiral bit.
I'm curious how I could do the calculation to determine if the area underneath my piece, coupled with the vacuum source I have will be enough to withstand the cutting forces.
Thanks
