A few questions about these. First off, I'm not terribly interested in the detail of the finished product. These seem to be toy soldier molds rather than historical miniatures molds (if there really is a distinction, but that's another topic
), however, I AM interested in the following:
1. How well do they hold up? Are they good for hundreds of castings, or do they start to chip and pit after a few dozen?
2. Do the molds fill pretty well immediately, or require extensive venting?
3. Will pretty much any metal from 60/40 lead tin to 40/60 lead tin do, or do you have shrinkage problems with the greater lead content molds?
4. Any hidden traps for the unwary that I'm not thinking of?
Now, please don't take this next statement the wrong way, but I know that, in the spirit of good natured help, SOME TMP members sometimes have a tendency to run off at the mouth on subjects about which they have no actual experience, and, as I stand to make (or not) a substantial invetment here, PLEASE RESPOND ONLY IF YOU HAVE ACTUAL EXPERIENCE WITH DUTKINS 54MM MOLDS. Not with Dutkins 25mm, not with Prince August molds, not with making molds out of RTV in your basement, but with these specific molds only. As any experienced caster knows, the difference between molds from different manufacturers, and, especially in different scales, can be enormous.
Again, I'm not trying to be snide, but as I said, I stand to make a substantial investment here, and really need good, informed advice only, not speculative well-wishing.
