Vacuum pod unit
Vacuum is a great way to secure work pieces, on the cnc, or on your workbench as well.
Inspired by Festools vac-sys, I decided to build a similar system for my workbench, for a loooot less money then the expensive commercial one.
I wanted it to be a simple construction, with a single operating lever for both direction of movement.
As you can see in the build video, I already have an old steel unit, that works great, but I loved the challenge to try to replicate it.
I also made plans for it so that anyone can build it.
the pods can be custom made in any shape and size to fit personal preference or product.
Its built from plywood, A piece of tubing, some pneumatic connectors, and a switching lever for the vacuum on/off.
The vacuum pump is a compressor salvaged from an old fridge.
If you want to see how to make a homemade vacuum pump from a fridge, take a look a Sam`s Workshop Diary`s new thread here on HTN, you can find it here: http://www.homemadetools.net/forum/h...uum-pump-71121
Personally, I just ripped the compressor out, and connected the hose to the inlet. (a little less work)
Here is a video of the vacuum pod build:

Outstanding video and build, Roy. Curious of what kind of vacuum pump is required, like a refrigeration pump?. Thanks for sharing another great build with us!

Thanks for the kind feedback PJ. I just used any old refrigerator compressor. Yanked it out of the fridge and cut the pipes. Just connected the pipe on the suction end to the hose, and voila!!! I have heard it is wise to put a drop of oil in the inlet from time to time, but I have never done it. I have had mine for years and its been running for hours and hours. A couple of times I have actually forgotten to switch it of, as it is extremely quiet. Nad It has been running for a couple of days. It was hot, but still pumping
The main thing about refrigeration compressors imho, is maintaining your oil level on an open ended system because they will put a small amount of oil vapor into the shop without a baffle or muffler. The pump gets most of it lube from the oil bath...a drop or two in the inlet may help with the valving in the long run, but not necessary, imho.
Thanks again for your post and response!
