RCBS makes a fine pot. I love it. The Magma pot is also nice. It is not so ergonomic as the RCBS one, but a 40 pount capacity is really, really nice. It is enough for most every cast session. You rarely need to refill it exept between sessions. Its downside is the price.
I have a friend that has a shop. I have approached him about making a 40 pound melting pot that would be similar to the magma pot, but with some improvements like a better sight line to the spout on the bottom and an RCBS style mold guide that is easier to adjust.
We are looking at a price point of around $400 dollars with about another $100 for a pid controller built in as an option. We are not offering these at this price yet, as we have not made a prototype, but this is just an exploratory post to see what the interest would be like for such a pot at this price point. If there is strong interest, we will proceed to development.
So if this sounds like something you would buy if we offer it, just post that you are interested. But please only post if you really think you would buy one. Also, any ideas you have for making a better pot I would be interested in.
