To right Dave! The price of a resin kit is silly money, I am more interested in conversion sets.
Yer ok, many of the conversions could be scratch built out of rod and sheet. The problems arrise when trying to fine all the drawings needed to get some thing that resembles what you are after. So in a nut shell Im a lazy git, who would rather buy the parts and get on with it.
As for the 'more detail' part of your comment Richard, I agree that some of the resin parts I have seen on the WWW I would not even pay half price. Bubbles, masive mold lines etc., and very poor detail. I think the real point is that some of the resin kits are made with more detail as the person doing the castings has more time, goes after the best result and is often also a specialist on the subject, where as a large firm making tools for injection molding has a some what larger out lay, and the complexity of the part is limited by what a machine can handle. A guy in a shed with nothing but passion and time can give it as much detail as he can without the worry of wasting his investment.
Ray, thanks for the tip about keeping it wet to hold the dust down. I hate super glue! Wonder if Gator glue can handle it?
