I’m thinking of buying one for smaller parts. Just curious what people are using and what types of pump are being used.
I use vacuum pods instead of a full table, which means I can use a smaller pump. I have a Gast pump that is sold as a vacuum bagging system for veneering. It works extremely well, but I’ve not used more than one pod at a time. I think three would be about the maximum this pump could support. I believe it’s a 0.6 CFM (very low)
If you have a compressor you can also try a venturi vacuum generator.
They’re super noisy though…
I have a small vacuum pump already I’m trying to find a good way to mill lots of little parts
You might find veneersupplies.com a valuable resource. https://www.veneersupplies.com/products/Podz-Vacuum-Clamping-Jigs.html . There’s a lot of information there about building vacuum systems for hold downs, etc. Also joewoodworker.com . Using info from these sites, I made some small vacuum hold downs from HDPE and the vacuum sealing tape they sell as well as the rubber seals used on canning jars.
