Bismuth rich alloys get totally stuck in WJ cavities.

You don´t say :)

Thanks a lot! :icon14: I´m working on a completely new (to locals) class of lures/tactics, shiny light heads would do wonders :cool:

Tin is an ideal casting metal - 450* melt, high luster, corrosion resistant, 2/3 lead weight - for shallow water apps. Except for the price - seems to have dropped slightly to $15 per lb. if one shops around. How much does tin cost in Europe?

If you get a Wobble Jig mold, luckily the ultra premium heavy wire Owner 5313 is miraculously a stock fit - 3/8 2/0, 1/4 1/0, and 1/8 #1. Repeating that the newer ruff face cavities Do-it molds might stick WJ castings.

Just checked, its a little less here, 17€ per kg plus postage which is about 12 $ per lb. As lead-free merchandise is not part of my marketing, I wonder if I can get away with a cheaper 40-70% alloy without making it too hard for the WJ mold.

5-10% Tin alloy is way to hard for sure. I used to pour with that in order to get extra durable heads for urban fishing under bridges and so but the effect is not worth the trouble.

BTW my upside-down WJ molds have returned from the engraver, looking great! :cool: Will post on the other thread once I have testet a few casts in the water.

Supposedly, tin added to lead improves flow-ability, but my experiments with pure solders on their own like 50-50 & 60-40 tin-lead was not good. Could not get full cavity fill out on small jigs with pot & ladle, but maybe a bottom pour melter is OK.

Hardening lead in my experience requires antimony. Some casters have posted using linotype which is super hard, have no idea how they remove the sprue. Lyman #2 bullet alloy Pb90-Sb5-Sn5 poured larger jig heads reasonably well for me and is pretty hard, tho not like vintage 80-16-4 linotype.

I remember some really concerned looking faces at the yunk metal yard when I told them I wanted to pour with linotype at home. This antimony is said to be nasty stuff. Nothing to pour with in the cellar, and I won´t give my neighbours something to talk about by wearing a respirator mask in the garden like a freakin`Darth Vader. :s

Have had fill-out issues with the wj mold in particular, so pure tin it is, thanks!
