Steve, your propossed method sounds very much like sintering, the way Tungsten Carbide tool tips are formed, its used to form other metal parts. Ian S C

Metal Clay even the bronze /copper stuff is as said ferociously expensive…esp. the non precious stuff( vis metal price)..But might fill a gap( no pun intended).

what about "micro foundary"… at least one system offered using domestic microwave oven. works for brass and ali… working on stell apperntly.

Sorry for spelling in a rush.

Hi jason

Thanks for that link the digitising probe looks interesting. As I understand the process there is an eletric micro furnace with cruciple included in the kit. The domestic microwave is used to melt the wax from the investment plaster cast and vaporise any remaining wax. The metal is then melted in the supplied electric furnace and poured into the mould. This process is for small parts so should suit some model makers.

Hi Steve,

Have a look here microwave casting.

Hope this helps.

Andy, if you used the bronze material, perhaps you could make Oilite bushes, this could be very handy if the real thing was unavailable.

There is quite a bit on the net about microwave metal casting from what I remember. Ian S C
