I'm looking to cast a few small bits with sharp edges and I think everyone knows how much of a pain it is to sand&file greenstuff. Maybe brownstuff is the answer.
Have any of you ever tried brownstuff casting? I'm thinking I should create the initial mold in greenstuff so it stays malleable and I could peel it, but would brownstuff work as copies or would they harden and be impossible to remove from the mold?

I use brownstuff casting for various bits on my termies.
Use fimo or sculpy putty for the form, and then use some type of lubricant in the mold as a release. I use food grade lubricant made for ice cream machines, but I imagine using even easier to find lubes such as astroglide, etc would work just as well.
here is a nice tutorial for you:

Thanks for the tutorial and advice HF. I also appreciate the new excuse for buying astroglide.

Here is another good tutorial for it:
http://www.drunkdwarves.com/pages/artttgttccasting.html
This one specifically deals with making molds for detail that is on a miniature (not that there is too much difference, really.) There are a few good articles on this site if you poke around a little.

As a small update, I have stopped using the food grade ice cream machine lubricant. It isnt as water soluable as I would like.
The reason this is a problem is that the lube wont wash off easily on these tiny tiny pieces, so it becomes a waste of time making them as primer wont stick to them. This has caused a huge delay in my project, as I made 75 of these brownstuff casts for 75 termies and now they are all useless because I cant get the lube off...
So stuff like petroleum jelly and food grade lubricant simply wont do.
As silly as it sounds, it really does look like astroglide will be the best bet. It washed of great with warm water with no scrubbing being necessary.
by the way, I tried talcum powder and I found it not only tons more messy, but that it doesnt leave the surface as smooth as does the astroglide.

I have casted a few things. I didn't use brown-stuff or astroglide(not sure what it is, sounds kinky) I used alumilite & thinned out fiber glass resin. I used silicon spray as a release. It came off w/dish soap & a soft toothbrush. Maybe that could help? The only problem I had was air bubbles in the resin.

Nah, Astroglide or KY are the way to go. I haven't started casting anything, but remember the rubber pollaxe I have by the door Shrew? That's a 1.5" rattan shaft in a 1" hole. Lubed it up and jammed it in, then a quick rinse of hot water and that bad boy is probably impossible to remove. It really is a great sort of thing if you want to have something lubed one minute and clean the next.
It also has other uses, in a pinch, and doesn't stain cloths.

Yep, sure is!
Seriously though, I've been using dedicated mold release stuff from Smooth-On. Comes in their resin casting starter kits, or you can order it separately. Then again, I've only done resin casting, not putties like that.

Have you tried soaking them in a cleanser like Superclean or Simple Green? A nice soak and a light scrub while rinsing should take care of any lube residue.

Brownstuff is sculpting putty, sort of like green stuff only it holds a sharper edge.
