Materials

My choice was SRBP-P1 board 20mm thick. The finished size is 465x300mm. you can use anything that is flat and not breathable or porous as the pressure of the vacuum pump can escape through it.

Tools

Shaper origin, 6mm single flute up spiral cutter (depending on the material you use), a vacuum pump, 7mm neoprene sponge cord, M6 threaded brass inserts, M6 thumb screws, 6mm dowels (I used stainless steel rod), any material for the side stops (I used stainless steel flat bar), brass hose barb.

Instructions

I have designed this to be used with the workstations shelf. The holes match up and screw straight on. All lines are on-line cuts. The depth of all the cuts for the seals is 4.5mm, I have found this gives the perfect seal using 7mm neoprene seals. The holes for the dowels will need to be deeper and you might need to be mess around with the hole size to get a nice fit for the dowels you're using. The hole for the barb needs to be matched up by drilling in the side and down when two of the cuts meet and away from the edge, I did this separately using on tool options. I then used 5 minute epoxy to set it in place, I have also used this epoxy to fill some accidental holes I have made whilst using the plate. make some small circles using the cord to seal around the screw holes, once you have the size right, use a drop of superglue to join the ends. I seal around the perimeter and put additional bits within the plate depending on the stock I'm machining. Never stretch the cord because this can cause leaks and drops in pressure. When machining, don't cut all the way though otherwise you will loose pressure and damage the plate. I leave about 0.5-1mm, cut out with a bandsaw or jigsaw and then trim flush with an upcut 6mm bearing guided cutter on my table router or palm router. Check out the video in the link and message me if you get stuck. I have used this plate so many times, I love it! happy Shaping!
