My latest project. It looks like a regular head but is it lead? NOPE.

A bismuth tin jig head. 8-)

Nice going!  What is the size to weight comparison vs. lead?  (just for reference)

its a bit lighter.  The 3/4 oz jig head 415grains  lead weighs about 350gr in bis/tin.

It would probably be close to a true 3/4 oz jig after the weedgaurd and paint and might go over with the skirt.  I havent weighed a built one yet.

Looks like a great alternative, let us know how the building process goes. I am particularly intreseted to see if there are any changes you have to make in the powder paint process. How much of a price difference do you think will be in a jigs of this material?

Thanks

Ok some questions???  what mix are you using 60 bis/40tin, 70/30 52/48???

Is there much difference in the heat versus what's needed for lead??

How much or was there any problems in removing the spru??

The biggest one is if you've powder painted them do you have to reduce heat length of curing time etc???

Last time I checked 60Bis/40tin for 1 pound was about $14 dollars.  A buddy over at TU offered me a few pounds to try at that price but I'd like to see GMAN's replys before I go for it.

That's neat, and a very worthy project!

It was 60/40 if i remember right.  Cost me about 40 dollars with shipping for 2lbs.  That will give you an idea of cost per jig.

I havent fished the ones I've painted yet but I had to reduce the cure temp to 250 for 30 min.  So I'm not real sure on durability of paint.  I used this temp because that is what was recommended for jigs with weedguards in them.  The bis/tin melts alot lower then lead an pours nicer but is alot more brittle.  The Spur for me broke cleaner then lead but make sure you wear glasses.  It doesnt break like lead and it will fragmen.  Also,  there is a learning curve for removeing bis/tin from molds.  Unlike lead this alloy expands when cooled. :-?  i''d stick with simple designs.  The poisen is a pain.
