R4360 Posted January 8, 2014 Report Share Posted January 8, 2014 I need to cast 8 engines, I nearly done with the master. Micro Mark has a nice all in one kit, but it's pricey at $100 - see the below link. Tell me what you've used? http://www.micromark.com/complete-resin-casting-starter-set,8174.html Scott Link to comment Share on other sites More sharing options...
Mark Aldrich Posted January 8, 2014 Report Share Posted January 8, 2014 Scott, I use the MicroMark Rubber, and Alumilite casting resin. Really good results. Mark Link to comment Share on other sites More sharing options...
drhornii Posted January 8, 2014 Report Share Posted January 8, 2014 I like Smooth-on. http://www.smooth-on.com/ One advantage of buying the resin and silicone from a manufacturer is the shelf life. You can buy Alumilite at Hobby lobby with 40% off coupon but you have no idea on how old it is. The shelf life is typically 6 months after it has been opened. I have had sucess after 6 months but it starts settin faster thanb advertised. Alumilite sets nice and hard but not much working time. Smoothon 321 has a little better working time and acts more like plastic when set. I pressure cast and working time really comes into play......

Eric Posted January 9, 2014 Report Share Posted January 9, 2014 If you have a TAP Plastics near you they carry RTV mold material and 2 part polyurethane resin. I believe I paid around $60 for the mold material and resin. Eric Link to comment Share on other sites More sharing options...
