casting a material in a clay mould
Looking to make a 15mm spacer for an airbox, there is a very complex pattern on the bottom for the throttle bodies, so was thinking of making an
impression in clay of what is required then casting it in plastic or hard rubber. Any ideas on what material I could use?

Would fiberglass resin (polyelster or epoxy I guess) work? It'd be a bit brittle if just resin but you can get reinforcing material to help bind
it together, kind of like the usual fiberglass matting but looks like its been blended into a fluffy powder like

Used wax as a pattern to make a mold in sand years ago at school , wax was then melted out leaving a mould into which we poured moulton aluminiun .
Just a few casting marks to cleaN OFF AND JOB DONE.
