Eben you are right on the money, making a good mold is harder than it looks.
The good thing about bondo is once its dry and hard, you can work with it pretty easily. It drills and sands easily and seems to stand up to the heat really well.
At 12$ a lb for tin solder, it's not going to really be much cheaper to make my own tins, so I won't be making too many of those...
The lead ones are much, much cheaper to make, so I'll probably make a bunch of them and and just spray paint them the colors I want. I think I have a can of chrome spray paint kicking around somewhere... the good thing about these, is when they get too beat up from the rocks in the canal, i can just hit em with the torch, melt em back down and start over.
Next year I'm going to mess around with this stuff a lot more. These were really just prototypes to see how hard it was to work with this stuff, and to see what kind of quality I could get.
