help with making molds for scibor-esque armour

@freakinacage, thanks for the welcome and the vote of confidence!

@No Such Agency, soapstone is great idea. I\'ve used it for casting pewter before. The only thing I found with soapstone is that it takes a lot of patience and it holds detail in all the places you don\'t want it too! It helps to have an electric drill with various sanding/shaping heads.

I saw this and immediately started thinking of my rotary tool and its flexible-shaft attachment... now, the question is: where would I go to get soapstone, if I really wanted to give this a try? ???

Actually, if I just wanted a hard slab of something flat that I could try to scribe with the rotary tool, how would rolling out some Milliput or Sculpey work for something like that? They\'re said to be drillable and sandable after they\'re cured/baked, so they should be scribable too, right?

Yep, milliput at least is perfect for scribing when it has set. I think that\'s what Cyril used when he make his article (iirc).

Nope, he says himself that he used Super Sculpey.

@Iahatiel - You can pllace putty between two pieces of wax paper so it won\'t stick, and then roll it out. It should be scribable, but keep in mind that Milliput sets very much like rock or hard plaster, and some great force can break it into shards.

lahatiel, I got my soapstone from a friend and sculptor who\'s primary medium is soapstone. She got it from Brazil at a great discount cus she bought a whole truckload of it! I\'ve also seen chunks of it in my local art stores. Even if yours doesn\'t have it, it can be worth asking because they might be able to order it, or know other people who have it.

mmmmm... rotary tool... I steal my housemate\'s all the time for sculpting, he has some really tiny heads for it, and its great for getting an even finish on larger areas.

To keep your pieces from sticking to the mold or stretching, get yourself a can of mold release lubricant. Works wonders. In the States you can order it from 2 companies I know of: Smooth-On and Alumilite. They both make rubber compounds and all sorts of casting resins for various purposes. I\'ve been experimenting with some of their stuff lately. Anyway, just spray your mold with 2 coats of universal mold release, let your green stuff dry and it should come right out of the mold. Something like WD40 might be just as effective as well. Green stuff doesn\'t seem to have any sort of reaction to exposure to oils, so any type of oil base lubricant should probably work as well.
