Is it really too difficult for the non-experienced?
EXAMPLE:
I’ve been trying to find HO scale crates of fruits & veges with no success.
I’ve heard of people casting their own details, so now I’m considering doing
it myself, and future detailed parts too.
John - This is another one of those subjects that can’t be done justice to by three or four sentences or a brief paragraph on a forum like this (but I’m sure several folks will naively try!). Use MR’s magazine index to locate previous articles addressing this subject in MR, RMC, etc. and get a copy of one of them as a step-by-step reference. Casting model details isn’t at all difficult but you must fully understand the process and how to go about it properly to create good molds and cast perfect replicas.
