Spike Posted February 28, 2005 Report Share Posted February 28, 2005 Have any of you guys ever tried making a jig head mold out of Durhams or plaster? I was just wondering if it could take the heat of molten lead and if it holds too much moisture, not a good mix with molten metal. Thanks.

jigmeister Posted March 1, 2005 Report Share Posted March 1, 2005 I have made a few molds out of Durhams and it does work but you have to make sure all the moisture is baked out or you'll end up with an eruption like a volcano out of the sprue hole after the hot lead goes in . Its good for making making some prototypes to test but not very durable . I am going to pick up some GE 2 part pourable hi-temp silicone (RTV #60)and try making a 2 part mold the same way as with the Durhams Quote Link to comment Share on other sites More sharing options...
siebler_custom_baits Posted March 1, 2005 Report Share Posted March 1, 2005 One thing i hate about these olds is how you gotta clamp them, That factor right there makes me go with hinged molds Quote Link to comment Share on other sites More sharing options...
