Making stuff
Ok, I have made quite a few molds and produced parts I need, so I can lend some experience to the topic.
About copy rights - what you do with it is the entire crux of the issue. If you are making extra beakie heads then you are ok, if you are making casts of Centurious and trying to sell them on ebay, then you are a dirty bastard for a number of reasons.
Anyway, it is entirely possible to make very decent casts. It takes a little practice and experimentation, but you can get some very acceptable results.
First of all, I used supplies available from www.micromark.com. I bought their molding and casting kits for about 60 dollars. You get two part RTV rubber, two part casting resin, and some useful accessories. There is plenty of stuff for a lot of molds and casts.
I first make a little box out of plasticard. I find it easier to suspend the master from a little rod rather than half bury it in modeling clay - but its really your choice. Pour the mold one half at a time (filling up to the middle of the master on the first pour). Before you pour the second half you cut some notches in the first half to create alignment bits. After you pour the second half, you cut some channels for the resin to flow in.
Its really trial and error - I\'ve made some molds 2 or 3 times because I found that certain parts of the mold werent filling etc.
It also helps to make a simple mold of a barrel or something for your first mold. Not only is is hard to mess up, it gives you a mold to pour extra resin into to reduce wastage. When you are making small parts there is always resin left over and making some bit for scenery or something sure beats wasting it.
If enough people want to see an article, I can put one together.
