Want to try epoxy resin casting and needed a vacuum chamber to pull air bubbles from resin and mold materials. Had an old vacuum pump from a prototype and bought a 3 gallon vacuum pot from Vevor. Had to design and print some mods to the pump to make it usable. Then I realized it should also be able to seal mason jars. This is a link to the TD relay instructions and programing icstation.com/110v-120v-programmable-digital-cycle-delay-relay-timer-switch-module-265v-display-999h-p-12364.html
The pump and all electronics were takeoffs with no part numbers so box wouldn't help others. Vevor also has a chamber with pump combo that should be in the youtube link to the products above.
