Hey guys as a heads up. In the lab if we make silicone we always degas the mixture before pouring. To degas just put the silicone after mixing into a closed container and pull vacuum. I think even a cheap aspirator will pull enough vacuum to work. Pull until the bubbles stop than you're good to go.

Both look promising. Google degassing silicone for more it's a common technique in soft litho.

Edit: For a chamber just get a plastic dessicator. They aren't that expensive : https://www.amazon.com/United-Scientific-55204-Polypropylene-Polycarbonate/dp/B00ES3GPMM

Edit2: Cus degassing silicone just looks so pretty : https://www.youtube.com/watch?v=bbSvzD8g_S0

Edit3: Decent part combo for degassing

Remember keep the vacuum so that it slowly degasses you do not want it to bubble over and all into your chamber.

Good vacuum, fast, cheap. Pick any two.

To meet your criteria this one linked below is under $50, will pull a better vacuum than most mechanical pumps, but very slow by comparison. Also wastes a lot of water. Probably not suitable for the task.

Lowest priced practical pumps will be Harbor Freight or local equivalent starting at $100 and more like $250 for anything over 4 CFM. I get them over Craigslist for sub-$100 (7CFM in that case). The decision on CFM is a factor of vacuum chamber volume and silicone working time.

Good luck with that search!
