I have a pressure pot and I thought it would change my life, but it didn’t. The air going into the chamber DID move the resin and the embedded items. So, I purchased a great rack designed for using in a modified paint compressor from Harbor Freight. Here is the link for the rack

My son helped me convert the thingy from Harbor Freight, but honestly, if I had it to do over again, I would have bought this: htps://www.artmolds.com/pressure-pot.html. After all was said and done, they probably ended up costing about the same amount of money, and less effort with the ready made one!
