This was the original video which gives a few more details on the pump used.
I’ve been using this vacuum casting set up and it’s been producing great results. The original failed when I the flask had a crack and molten bronze hit the aluminum.
The laser cut flange ring was purchased at
www.coremarkmetals.com
Steel pipe is expensive but I found this piece in their scrap metal bin. It was still $3.00 a lb
The pump is an 8cfm 2 stage vacuum pump.
It cost $160
