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.
