Well here she is. My new Vacuum Chamber and Pump.
I just tested it with a few parts, and it works quite well. However, it moves the small bubbles quite well from the surface detail but you have to manually remove the large ones first. So just like a drop pour you need to pick out the large bubbles then vac the part.
But I'm sure with a bit more practice and rework a few mould designs I more than likely won’t have to pick out the bubbles.
Hello full scale production!!!!!! Well maybe not.

Cheers Jason

Intriguing - did you purchase it 'as is' as a whole unit or as pieces and you built it?

This looks pretty cool.

It's the opposite of My Setup. Same thing Only Pressurizing the chamber instead of vaccuming it.
