I have been using pewter for about 20 years now for making models.
Great to work with… easy to carve and finish and mold. Super easy
to cast with the right equipment.
Source for Pewter that I use is Contenti.
Great people to work with also.
You do need to keep your work space clean if you are going to be
using precious metals on the same bench. Pewter will contaminate
your metals. I use the lead free pewters and solders. For a flux get
the water soluble ones they clean up much easier with a little warm
You can hammer it out much more then other metals so you do not need
to anneal it while working with it…
You need to use a elect soldering iron or a soft broad flame torch
like one of those propane hand held torches that you can refill…
Contenti sells them for about $40 but are a worth while investment. I
do love working with it. You can cast it into rubber molds and if
need be can make molds that are gravity cast able. I have a complete
pewter shop where I make my models at as well as fishing lures :-)(
have to keep my priorities in line)
