I fabricated this vacuum pump with an old fridge compressor.It pulls 24Hg. Will this work for vacuum infusion?
The resin would have to be very low viscis (?) and the part would need to be small or very narrow. What are you wanting to make?
It will work better than nothing…and better than other things out there too!
That’s pretty much what I use…'cept I plumbed an old propane tank into the pressure out side, with a regulator and blowoff valve on that, so it does double duty as an air compressor.
