Introduction: Vacuum & Compressor
Simple vacuum pump for veneer pressing, board building. Also doubles as a low volume compressor for small airspray jobs. This is presented as a tool for building stuff, I've been using it for years and built it without documenting the process therefore its not really an 'instructable' but more of a general plan for creating the tool. All thats needed to put this together is a 1/2" wrench, some PTFE tape and parts from http://www.joewoodworker.com/veneering/welcome.htm

Step 1: Pump
Step 2: Vacuum Bag
The vaccum chamber is made up from three PVC drain parts from my local hardware store. There's no special joints, every mates up edge to edge and I just glued it with model glue with melts the plastic together. I thought it might cave in when a vacuum is drawn but it holds up suprisingly well.
