its all about technique with the airbubbles and the open void of the mold for the big piece makes it easy. Resin sets up quick no matter how much there is, it was just figuring the amount out which takes only one pour to do. The washer wasnt too much more tricky although I have a question about it.
Here are the pics of the masters and the casts.
The question is about the nipple around the hole of the master washer. does it need to be there or not. I can get it to cast but it is very thin and needs to be reinforced with superglue if we need it there. Here is a shot of one with and one without.
Now, I still need to fab up one of the 5 pieces that we believe will make the clear piece. Now, that mold will be open topped as well and getting air out of the clear stuff is actually more possible since the clear resin sets up so much more slowly. Its all about degassing after you mix and while you pour as far as getting the clear stuff to turn out bubble free.
I will make 1 master, mold that, make 5 castings, make a mold for all 5 of those, and be able to cast the 5 smaller pieces at once which is needed since the clear stuff takes 24 hours to cure vs several min like the tan stuff.
