Is it possible to melt tin in the same equipment that I use to melt lead?  Obviously I'd have to clean the lead out.

Tin is denser and would give my jigs a little bit better feel of what is going on down there.  That and I have about 20lbs of the stuff now.  If I can even melt it, would it screw up my molds or melting pots.  Does Powder paint stick to it?

I know evolution jigs are made of tin. You should ask BobbyMegastrike, maybe he can help you out.

If the density of lead is 1, tin is a .63.  It's also pretty soft, much softer than brass or tungsten, or steel for that matter.  Switching to tin would be a environmentally friendly idea, but won't increase sensitivity...on its own.

Pure tin has a melting point of 450 degrees.  Tin and bismuth are often mixed to make an alloy.  Bismuth is almost as dense as lead, but it is to brittle to be suitable for a jig on its own.  So, the bismuth adds density and the tin tempers the brittleness of the bismuth.  I'm not sure of the best ratio, but they have more bismuth than tin.  The melting point of alloys are often times less than their components and should be attainable without special equipment.  I don't know how to make the alloy, where to get the metals, what tools are needed, etc.  Just a basic understanding of the metals.

Search around TU, I'm convinced they know everything.  

Contact your pouring pots manufacturer and ask them if it's ok.

I've assumed that bobbymega used a tin jig head because of it's density.....and he cares about the environment.  Couldn't have been very easy to make normal sized jig head + skid/rocker plate out lead and not turn a 1/4 jig into a 3/4 ounce jig.  I know this isn't very well explained, but you get the idea.  I'm not knocking the evolution jig or bobby and it's obviously an innovative, successful idea.
