So I was pouring resin for a hybrid bowl and got one of those "stroke of genius" ideas - what if I briefly put the bowl under vacuum before putting it in the pressure pot? It works for stabilizing resin so why not casting resin?
Well, the answer in part is that the casting resin I used has a 12 minute working time so it was already setting up when I tried this. The result is a giant blueberry meringue-looking bowl blank with more and larger voids then the wood blank I was casting had to begin with.
I'm hoping the foam is mostly on the top of the mold since that's the bottom of the bowl and it will mostly get cut away. But it may end up as a total loss. Will find out once I cut into it over the weekend. That's a lot of resin to waste if it doesn't work out. And I'm reconsidering that whole "stroke of genius" thing.
