atijigs Posted April 4, 2011 Report Share Posted April 4, 2011 (edited) I usually can get any mold to pour. This Ultra Minnow spinner bait has to be poured with pure lead. (IMO). I am a fan of soft lead for pouring but that is not what I had in the pot at the time. I have poured for years so I know most of the tricks but this one beat me today. Next time will be with pure lead because I hate breaking down mis- cast spinner baits, I did a search on this and found others with a similar problem. I think the solution will be pure alloy. I will report back in a while when I try it again. Edited April 4, 2011 by atijigs Quote Link to comment Share on other sites More sharing options...
mkvnmtr Posted April 4, 2011 Report Share Posted April 4, 2011 Like you I think I know most of the tricks to get a pour to work. It seems like some days nothing I do works. I just put it down and try later. I think maybe humidity or something just makes for a bad day. Quote Link to comment Share on other sites More sharing options...
toadfrog Posted April 4, 2011 Report Share Posted April 4, 2011 I sold my mold for that very reason . Just got sick of fooling with it. Be careful when you demold . If you take it out by anything but the sprue it will cause the head to have a curvature when using pure lead. Quote Link to comment Share on other sites More sharing options...
smalljaw Posted April 4, 2011 Report Share Posted April 4, 2011 I found a way to pour that with a mix of soft lead and some wheel weight lead but you need to use the ladle and "dump" it in the gate instead of pouring it in. Quote Link to comment Share on other sites More sharing options...
Tony Maxwell Posted April 4, 2011 Report Share Posted April 4, 2011 I've been pouring the ultra minnow heads since they first came out in the jig version. I promptly modified it to pour spinnerbait heads from 1/8 oz up to 5/8 oz. I use wheel weights and a ladle and have only had problems with the 1/8 oz. heads. Finally dremeled out the collar end to resolve issue. I do smoke all my molds prior to use and make sure my ww is really hot. Good luck.

cz75b Posted April 9, 2011 Report Share Posted April 9, 2011 try a very hot mold, cavities coated with light spray of mold release and a high tin content alloy like wheel weights, make sure your hooks are warm too by seating them and using a torch on the mold sides. Keep your pot hot and alloy clean and pour with some head, from the spout if you can on a bottom pour. Soft lead melts at a very high temp and has poor mold filling out qualities. Don't believe for a minute that soft (pure) lead is the best for casting jigs with details, it ain't. Make sure your mold is clean before you apply the mold release. If you use release over a dirty/oily mold, it will never work well. When in doubt, boil the mold in water with dish detergent and rinse very well and dry. trace oil in a cavity is not your friend. If you can get your hands on some linotype, your jigs will look like jewelry, high tin/antimony is the trick, this stuff flows into the cavity details. Good luck, you will figure out a technique that works and get into a groove..... Quote Link to comment Share on other sites More sharing options...
f150with20s Posted April 21, 2011 Report Share Posted April 21, 2011 I smashed a very small drop of lead in the inside of the mold where it opens, I have to do a little extra trimming but its worth it. Quote Link to comment Share on other sites More sharing options...
