Howdy everyone. Finally got my pressure pot system to stabilize without leaks (gobs and gobs of of "cast-a-gasket") and am going about making resin bases. The bases I have made have overhanging rock and tile, which make a large amount of air bubbles. In the past when I cast these, even if I used a stick or something else to clear the bubbles out, there were still a ton. I have cast the bases under pressure a few times now and they have come out perfect. The big downside, however, is getting the bottom of the bases even. So far, they have either sunken in because there wasn't enough resin, or ballooned out due to too much resin. This weekend, I am going to be doing some measured experiments to gauge the perfect amount of resin to use to cast flat bases. I will be taking pictures and posted them here.
In the meantime, does anyone have any advice or experience to give me?
