« Part 1: Starting Out Part 2 of Adventures in Vacuum Veneering series Part 3: Adding a Frame Press »

Woo Hoo, this is my 1,000 post. Another checkpoint in life.

I installed a complete complement of parts to make my vacuum pump more usable. I pretty much added a kit from JoeWoodWorker and followed his lead. My pump now is on a carrier with a handle and an On/Off switch. This alone would usually be enough for me to celebrate. But there’s more…

I also added a vacuum controller that allows me to dial in the amount of pressure that I want. It is the little black box with the black tubing. It directly turns off the pump. But when you turn off a vacuum pump, you must relieve pressure to the pump, or it will not start again. Hence the Mac valve which is the blue valve sticking out from the front of the pump. It is wired in parallel with the pump. When the pump shuts down, it opens up, and relieves the pressure to the motor through a breather fitting. But there is a check, or one-way valve underneath the Mac value, and a small reservoir out of PVC pipe above it. The reservoir will hold spare vacuum and helps smooth the starts and stops of the motor.

There are two large PVC canisters that I made that hold spare vacuum. These work just like the tank on an air compressor. I also have a gauge and a shut off valve. And I installed a filter to the inlet of the pump.

Great Steve. It looks somewhat like mine.

I have a mac valve also even though my pump doesn’t have a problem starting with a full vacuum. The problem that I had was the vacuum bleeding back through the pump and thereby causing it to come on sooner than normal.

Steve, that is pretty neat. I have got to get into veneering one day. It looks like it would be a lot of fun.

This is getting interesting. Until now I have just kind of not paid attention to veneering. Now I’m starting to think about the possibilities. Just what I need – more projects!

I just got to get to building me one of these pumps. Veneering has really got into my blood and I want to learn how to do it myself. Got to get me a pump built.

As craftsmen we create designs that revolve around our abilities. The vacuum press opens up a lot more possibilities with veneer and bent laminations.

You will love using this tool.

Steve,

Nice job on the vac, I have studied these on Joes site as well but I have not built one yet I still use my roarocket kit and hand pump, or a screw down veneer press.
