I'm thinking I need to make me some of these. I've been looking at a vacuum table setup but this might be the best of both worlds. With acrylic I tend to screw it down, but with these I wouldn't need to. Thanks! :cheers:

this would hold your acrylic ,the 1/4 piece of glass would not come off ...not
the pump is a gast 1/3 hp

also after i machined the plastic which is not like wood ,then i drilled and tapped for the brass barb
The next batch will be barb fitting on either end so all four hook up in series
Again the work piece texture is important the glass was the best ,the pump was pulling 20 in and with the plywood it was 18
And i have used a 1/8 pegboard if i have to cut through as you do not want to damage the oring
