instant mould (ebay) for casting the mould and then green-stuff/milliput for replicating the piece
I'd quite like to see how it turns out if you have sculpted a hand and weapon already, I wish I could design my own weapons!

Say I sculpted my own version of for example a crude Orc sword with a hand attached for purposes of converting miniatures, what methods exist for making a cast and subsequent moulds of this? I for example want to convert some Uruk Scouts into Mordor Uruks. I sculpt myself an orc sword and hand to transplant onto the weapon hands of the Scout models, what equipment and materials would you need to do this? |

I assume you'd have to put a lump of green stuff in it....and use gravity/force to push the 2 sides together and then take it out, and carve off the bad stuff? |

In my experience, instantmold isn't very good for two part molds. I think I'd be more inclined to use a proper casting latex for the mold, and make the pieces in resin. |

how would the instant mould work then because it would have one flat side to it so for a weapon it wouldnt work |

You can wrap the mould around a 3d object and press hard so that it is totally concealed and then leave it to set. Once set, cut the object out with a craft knife and you have a 2-part mould. Admittedly 1 sided objects like casualties are alot easier to do and make for good practice |

You can just wrap the IM around and slice it open to get at it once its set - cut it vertically and you will still have it all in one remouldable piece. |

If you do become confident enough to cast your own minis, try this guide to home casting: http://www.one-ring.co.uk/kb.php?a=149 |

Instead of Instant Mold I would suggest using polymorph. It is effectively the same material in a raw form and without any brand name attached to it. Oh, I forgot. It is much much cheaper. Example: http://www.ebay.co.uk/itm/500g-17-6oz-F ... 27c279e9ea On the other hand, press-molding methods aren't good enough for copying and reproducing crisp details. You should consider delving into resin casting with 2-part silicon rubber molds. The above link is a good place to start. Also there are many videos in the youtube that could help you... |

Personally, I find it useful for casting shields, faces, other things you can make a "press" mold with. Pressing the two parts together around a piece of greenstuff doesn't give very good results, but I suppose that does depend on how exacting your standards are. If wanting to cast something 3D, as per my earlier post and a few other people's advice, the best idea is to use a proper silicone 2 part mold. |

If wanting to cast something 3D, as per my earlier post and a few other people's advice, the best idea is to use a proper silicone 2 part mold. Sorry, I am a bit late. The best way is a silicone mold. 2 part would be best. However because of the expense I do not make silicone molds unless I need a hundred or more parts cast. I am going to recommend the instant mold. Here is a U tube clip from my friend Travis at Cool Min or not. http://www.youtube.com/watch?v=ub70AU5RfmI The trick to make a press mold with two sides is a clamp. Take two small blocks of hardboard or MDFB and a pair of vice grips. Fold the instant mold a round the part and quickly clamp it. You have to be fast. But that is the best way to make a few small parts. The mold will look like a book. If it is not flexible enough cut it into two parts. Place the green stuff into the press mold and clamp it. Wait for the ribbon epoxy to set. Then trim the flash. I have a Smooth On retailer near by so I most often use Mold Star 15 Slow silicon rubber. I do not have a vacuum chamber so I use the slow so more air bubbles can escape as it cures. It is 1a/1b by volume so I don't have to use my scale. I have used some of the clear products but they really need a vacuum chamber. So I will wait till I build one before I use them again. |

Be easier surely to just make tusks from putty. All you need do is roll out a long sausage applying more pressure at one end to make it thinner into a point. Then just bend it to the correct curvature and allow to set |

Then just bend it to the correct curvature and allow to set i tried, and this will sound dumb... but it went floppy and if i left it on a hard surface once cured it went flat on one side? I really am no pro at this in any way shape or form (sorry for post-jacking)

The trick is to use a hard putty such as milliputt. That way you can file it off a bit to get rid of the flatter side. |
