I appreciate the comments Mike. I've seen a couple of posts on other forums where it was used. I most likely won't be doing any large veneer projects, probably only a 2' x 4' bag at most. I plan to use it for stabilizing mostly From what I read on the Joe Woodworker site it takes about 1 cfm to do a 4' x 4' bag and 3 cfm for 4' x 8', but I don't know if that takes into account leakage, which I suspect will happen.
I figure I'll build the system and if the pump isn't big enough, all I've got to do is upgrade the pump and maybe a couple of fittings.
