Hey everyone, I'm an amature clacksmith, and I've been struggling with getting the bubbles out of my resin. I've been doing a lot of research but nothing I do seems to get the last of them out
I've been using Sig Wong resin: https://www.amazon.com/Epoxy-Resin-Clear-Crystal-Coating/dp/B084PZG6HK/ref=sr_1_8?crid=FZ5ZLF1M2VN&keywords=resin&qid=1682614661&sprefix=resin%2Caps%2C363&sr=8-8
And I follow these steps: 1: Float the bottles of resin in a bucket of hot water to heat up the resin and thin it out 2: Measure and mix the resin with a resin mixer 3: Let the resin degass in a vacuum chamber for about 10-15 minutes, I have a 1/2 horsepower vacuum pump that gets it to about 27 PSI 4: Pop the bubbles on the top with a lighter 5: Pour the resin in a high, thin stream into the die molds, overfill the die molds so there's a puddle on top 6: Degass the molds without the top on, same PSI as before, let it sit for a few minutes 7: Pop the bubbles on the top again 8: Put the lid on the resin molds
Seems like no matter what I do I can' get all the bubbles out. I've tried a bunch of different things, multiple degassing, thinner layers of resin, hitting it with a heat gun, etc
Am I just missing something? Is there something I could be doing better? Should I be using a pressure pot instead? Is there a better resin to use? Thank you all for the help!
