This hardly seems the place but I can't find another.
Has anyone used one of the Micro-Mark kits to pull a mould off a tinplate engine, specifically a Hafner / Wyandotte streamlined clockwork engine shell, in order to cast one from plastic?
What would be the issues, especially in weight if I made an engine from plastic and powered it with a Marx 999 motor?

Have not done that specifically.
I presume you mean making a mold and casting a copy in resin? Doable, but might be a bit of a complicated mold that might take some transient modification of the original. Would not use Micro-Mark resin for this due to a too rapid cure time - larger molds benefit by having a slower cure time and longer working time.
Nor sure I follow your concern about weight - resin is too light or tooheavy? You might need to make a somewhat thicker resin body for both strength and for mounting purposes.
Might you be able to provide a picture of your starting point?
Weight concerns traction. Will it be heavy enough to pull five tin cars and a tender?
Can't find a decent picture and my camera is in the south Pacific with my daughter and son-in-law at the moment. (Wish I were with them.)

Probably will have to add weight - resin vs. metal.
Have you looked at putting a #999 motor into a junkbox Hafner shell out of a show, or maybe off the net? Of course, if you've tried that and the shell needs severe modification.......

Got a shell that's really in great shape but wanted to find a way to lengthen it and make a 4-4-2 out of it. Maybe I'll look it over again and see if it isn't more practical to modify what I have.
Thanks.
