Vacuum Former Build
Currently, we scavenged a lot of parts from an old vacuum former with a lot of wear and tear. We are looking to rebuild the old one into a better version.
After talking with Nick, we agreed that we should post the parts list on the forum and begin collecting parts to get started on working on the Vacuum Former. I’m in the middle of compiling the list right now and we can work on things from there.
There are four material list that are for the vacuum system, electrical, wooden parts and steel parts. Here are the first two:

That’s a very specific parts list. Do you have the design handy? Would scavenging parts from a wall oven work for some of the electrical bits?
We actually have some good designs, drawings, and instructions in a binder at the makerspace. I just took the list of required parts and posted it on the forum. We scavenged a lot of parts off an old one, like a set of heating elements, compression motor, and other components. He have them sorted in a bin at the makerspace.
Do you guys have a pump already? I might have one from a beer-line refrigeration system assuming it is still in my brother’s basement.
We may have cannibalized the compressor from the original Vac Former, but I can’t guarantee that it works or not.
Progress was made on the vacuum former tonight. @Nicholas has promised that he will finish the project by Friday next week so that we can showcase it at our open house
@Nicholas is likely going to need some help, so if you are interested in this project get in touch with him and see if you can help out!
Let the count down begin!
@Nicholas I’ll be dropping by today (Friday) to see if I can help out with the Vacuum Former.
