Tips/Techniques An adventure in lost resin casting.

Do you use centrifugal or vacuum for pouring?

How high does your vacuum go maybe mix in something that will be like more porous when vacuuming

The whole project is exceptional, the handwheel is much more suited to the engine than the one the plans show.

Is the tool post your own design?

Tom its vacuum cast,

Vacuum should achieve 29". Tom, not sure what you mean, why do that?

Thanks Yotabota, tool post is based on a Tripan but miniaturized by me. The smallest they make wasn't small enough. It pretty small, tool bit shown is 3/16

I was thinking out loud wondering if the plaster could be made more porous for the vacuuming process without degrading the finish with some sort of additive.
