koreanjohn32 Posted June 29, 2013 Report Share Posted June 29, 2013 Does anybody know where I can find/buy those plastic registration keys that you insert into plaster molds? I'm doing a bunch of plaster molds for slipcasting and I just saw a commercial mold that has the keys in them. I'm finding that in tight spaces, trying to carve out plaster is tricky. Thanks in advance. Link to comment Share on other sites More sharing options...
Marcia Selsor Posted June 29, 2013 Report Share Posted June 29, 2013 I just made round key negatives with my trimming tools into the first section of the cast mold and then cast the other section of the mold which included the positive keys.

BeckyH Posted June 29, 2013 Report Share Posted June 29, 2013 I just twist a quarter into the plaster until it's half way down. Makes a nice smooth bump. Link to comment Share on other sites More sharing options...
