School Master Posted June 3, 2016 Report Share Posted June 3, 2016 I've been messing around with making some hardbaits out of resin. I am using Featherlite, and my problem is bubbles. I made a master, then made a RTV mold of that master. I get little bubbles in the top of the bait every time. Any chance anyone has a tip to help me get better baits out of the mold?

Hughesy Posted June 3, 2016 Report Share Posted June 3, 2016 You probably need to degas your resin in a vacuum chamber. Quote Link to comment Share on other sites More sharing options...
JRammit Posted June 3, 2016 Report Share Posted June 3, 2016 A pic of the mold would help Ive never had any bubbles in a resin bait, i always make sure the sprue is at the highest point, and pour a thin stream allowing any air to escape thru the sprue rather than getting trapped inside the mold Quote Link to comment Share on other sites More sharing options...
School Master Posted June 3, 2016 Author Report Share Posted June 3, 2016 I could be pouring too fast. I will throw up a picture when I get home. Quote Link to comment Share on other sites More sharing options...
token12 Posted June 7, 2016 Report Share Posted June 7, 2016 Hold your cup of resin above the mold to help pop any bubbles as you're pouring, thats one thing I do. I also mix until I start feeling the heat from the heat given from the reaction, then I pour. You can also look into doxy 5. It'll help eliminate any bubbles if you cannot degas the mix. http://www.theengineerguy.com/Doxy-5-Urethane-Degassing-Agent.html Quote Link to comment Share on other sites More sharing options...
