Vacuum table/vac former

[rkennerley]

I have gotten hold of some plans for a vacuum table that I need for my CNC machine, it has 3 vacuum plates in it but that is a bit long for my needs so

after some playing round in CAD I have shortened it to a single plate and that got me thinking why not a vac former as well.I did a bit more tweaking

in CAD and came up with a few extra bits that should make a good vac former.The 3 plate version generates -/+25kg of holding force per plate so a

single plate should generate a bit more than that ( there is a sum somewhere out on the web for working it out).It has cost £21 so far in acrylic (without postage)

not the cheapest acrylic but as I have no way of cutting bigger pieces smaller and with the 3 different thickness's involved it is just easer to get precut sheets

the right size for the CNC bed.What I was wondering was ,is there anyone else interested in having one or is it more of a "specialised" tool.
