casting papier mache
I don't think that papier mâché will be a suitable material for your
purpose. Remember that the finished product will effectively be made of cardboard and so is unlikely to be smashable. I would expect that a 3 foot long model microphone would probably only be dented. What about the material used to make breakaways? I'm thinking of the sugar-glass replacement. Unfortunately I have no experience of the stuff myself so I don't know whether it would be any use in this application. David ... or rather use regular resin. The breakaway kind is too fragile for this, IMHO. Here's another idea (not tested, but it might work): some sort of mixture of plaster and papier-mache. That should theoretically break better. |

The other possibility is to make the papier mâché very thin and finish it with several coats of laquer. I'm sure that there was a Russian tradition of laquered papier mâché boxes, which were hard.

I know esoterica like carton pierre - that is very hard, but still
lightweight for casting architectural and furniture ornaments. Now replaced by plastics, but still some people casting 'composition' for the furniture industry Plastics - no one has mentioned the possibility of vacuum forming the two halves in light gauge styrene. Ned could make up the positive in plaster, take it to the vacuum shop, and they could crank them out. This would be fairly inexpensive and very realistic (I mean Shure!). Not as breakable than mache, but a lot lighter and a lot easier to cleanup. Heck - you might even be able to sell them alongside band tshirts, cds, etc for X$ - the band will sign it (and send 10% of proceeds to me for the idea of course). Was it the Rolling Stones that had a giant inflable penis on tour? "David Lee" wrote in message ... Ioan Barladeanu wrote...

David If the OP does choose to go with papier mache, don't use strips of paper, use small fragments. The smaller the pieces of paper, the more easily breakable the same thickness of papier mache is. Ideally the size you want for mache that will break is what you get from a crosscut paper shredder (the kind that simultaneiously strips the paper and cut the strips into little bits.) -- Posted via a free Usenet account from http://www.teranews.com |

casting papier mache
When I visited the NY state capitol (Albany) the tour guide said a lot of
ornament (big brackets) were paper mache and it was considered a fire safety material. She didn't know why. I just know it's murder getting the pulpy stuff to dry reasonably quick so you might make armature of chickenwire so air can circulate from the inside too.
