BuckMaxx Posted January 5, 2015 Report Share Posted January 5, 2015 I have now outgrown some of my molds. I want to start making my own molds to upsize them. Is there a step by step video or can someone tell me how to do it? Specifically what rtv do I need?thanks!! Quote Link to comment Share on other sites More sharing options...

Slowfish Have u used both of the of the manufacturersThe reason I ask is that I have used many of the rtv Manufacturers but have not tryed smooth on And was wondering how detailed it was in the finer appendage's And was it cheaper Thanks jjk Quote Link to comment Share on other sites More sharing options...
SlowFISH Posted January 6, 2015 Report Share Posted January 6, 2015 I haven't used the smooth on - I had a co-worker that did - but he needed to pull vacuum on his mold to get the small detail in the part he was making. I'd call them up and ask.... but from prior experience - being able to pull a vacuum on a mold will help as it pulls the air out. To do so you will need a pump and chamber which can be bought off ebay/amazon... J. Quote Link to comment Share on other sites More sharing options...
