Another project?

Well it's more of a present to me and I realized it would help with my current repair job so I decided to just go ahead and build my own vacuum press system. It's pretty simple and I am following some simple and detailed plans from JoeWoodworker.com for the layout. I'll post some pictures when I get a little farther along (I'm still collecting the parts). I got some of the important bits from VeneerSupplies.com and I am waiting on a pump that I bought off ebay. Here is the basic layout.
I had thought about just going with a cheap-o direct pump to bag bang on bang off design but with just a little more care you get some really nice features. This design incorporates some relatively inexpensive parts to accomplish automatic vacuum regulation using an adjustable vacuum sensor and relieves the strain on the pump at startup with a sub-reservoir and a "mac-valve" (basically solenoid valve) after startup to suck air from the main reservoir and vacuum bag. Although Joe Woodworker's "vacuum press" is aimed at woodworkers for laminating veneers and such, I'll be using it mainly for bagged composite projects. I'm interested in trying my hand at a technique called resin infusion. Oh and did I mention, I've ALWAYS wanted one of these.
