Im pretty good at crafty things, but dang these things are hard. Got pretty close using potters plaster but even with vents the metal just does not flow for me. Took a bit of a side quest in modellers wax with the idea of carving the mini then making the mold using it, still on going. However it just feels better reverse carving into a mold.


As for the mold mold used a few different things from silocone to 3d printed deconstruct able frames but getting that super tight and even fit the slate molds have is also a summit of its own. Moreover plaster is messy as hell, been on the wrong end of the mrs wrath a few times to the the state of the shed  :D [size=78%]. [/size]


Ideally i just want to buy smooth even blocks and spend the time learning engraving. But that said its also a pretty good feeling when you first press in some plasticine to reveal a neat looking wee figure as testament to what amounts to an occult ritual getting there.

One thing. if using plaster you MUST make sure that it is all dry.
If you have even the hint of moisture in the mould when you pour hot metal in, you will get a blowback of hot metal through the pouring vent or air vents, this can be disastrous and very painful.
When pouring metal never look into or peer over the vent..
You need to exercise extreme care when pouring hot metal and make sure that you wear safety goggles and gloves.

BobLeighton:

If you are using dental plaster which you used to be able to buy at all branches of Boots, not sure now, if you look around the shelves  of the major retailers you will see that items that don't sell fast or items that only have a small profit margin are disappearing fast.
Once the plaster has been poured into the mould it needs to be shaken or stirred at the top to try and get as much air out of the mixture, air equals bubbles which equals holes in the plaster and also delays the setting time of the plaster. Used to use these type of moulds to war gaming figures in the fifties. If you can find some of the early War gaming books, they might contain some mention of the use of plaster.

If you cant steal Lego bricks from your children Plasticine is a useful alternative

Hi Guys,
First of all thank you for having the courage to prove yourself as a serious.

Gypsum stones are a good cheap start. But these should produce them first.

- optimally use 1 glass plate or mirror
- with LEGO bricks you can put the size together.
- use pourable dental plaster, optimally, it is a hard plaster with few air holes

You can also use cast ceramic

everything else I leave to your talent to teach from the experience. :o :) :)

BobLeighton:

Hope this might help, found it while looking for something else.
Always the way
regards
 Bob
