dlaery Posted November 16, 2012 Report Share Posted November 16, 2012 I have had good experience with JB Weld holding up to the heat. I would be more afraid of it not coming out if you change you mind. One thing it needs to be clean for the JB to stick. I have not had any good experience with welding on a mold.

Jig Man Posted November 16, 2012 Report Share Posted November 16, 2012 I have JB in a jig mold that I modified and got drilled too deep. It has been there for over 10 years and thousands of jigs have since been poured through that mold. I have one mold that I don't like the collar on but cast then take the lead off the hook shank. I cut it with gate cutters, flaten it with pliers then twist it off. That way I still have the collar if and when I want it. Quote Link to comment Share on other sites More sharing options...
cadman Posted November 16, 2012 Report Share Posted November 16, 2012 Yes JB weld will hold for many pours. The only problem is if you need to take it out, you will damage the mold especially in small crevices, because you can't get J B mold out cleanly. If you want to use the mold as a two part mold, better to fill the portion you don't want with high temp silicone. JMO Quote Link to comment Share on other sites More sharing options...
Basseducer Posted November 16, 2012 Report Share Posted November 16, 2012 Try a rubber skirt band around the hook shank and position it as close to the cavity as you like. Quote Link to comment Share on other sites More sharing options...
Tony Maxwell Posted November 20, 2012 Report Share Posted November 20, 2012 X2 on the skirt bands. They can be used over & over. Good luck. Quote Link to comment Share on other sites More sharing options...
atijigs Posted November 20, 2012 Report Share Posted November 20, 2012 Modeling clay works great and is removable. You don't need to fill the whole collar either. Just the 3-4 mms where the collar starts. Quote Link to comment Share on other sites More sharing options...
bass01 Posted November 20, 2012 Author Report Share Posted November 20, 2012 Thanks I'll try the other options before the JB Weld!!! Bass01 Quote Link to comment Share on other sites More sharing options...

Just the 3-4 mms where the collar starts. Is there a specific type of modeling clay? Quote Link to comment Share on other sites More sharing options...
atijigs Posted November 20, 2012 Report Share Posted November 20, 2012 You just need the kind that does not harden. You should be able to find it in any craft store. We always used it in grade school. I use it anywhere I have made modifications in a mold to eliminate any flash. It seems as it heats up it becomes slightly stiffer but never hard.
