OK, so all vac hold down talk got me to break the friction between my lazy boy and my butt. :p
I wanted to experiment with some hold down. I usually hold smaller parts than a full sheet. This is a sandwiched device that can be clamped or screwed to the table. The vac and the PVC board is one given to me by a friend. :D The 1st image is the top and the second is the base that is bonded together with the channels to allow the vacuum to make its rounds. In the fourth pic you see the small square with the gasket material. Unfortunately, its not usable. Its proximity to the vacuum makes it impossible for the cutter to get near it. I did not cut through to the vac ports so i don't need to seal this.
I added gasket material around all the sections. I also added rail slots on all four sides to allow consistent placements. In the 4th pic you see the the little squares with a little gasket material on the bottom. I set these on the holes and the vac holds them tight. Not a high tech solution but a utilitarian one. I had thought to mount the vac under but this was quick and easy.
I am astonished at the holding power of the vac! :eek:
1 hour design time
2.5 hours to cut
20 minutes to assemble
.25 straight cut 4ips on the top sheet
.5 straight cut 4ips on the top sheet
