    I am well aware that there are people casting all sorts of things in polyester, epoxy and other resins...and sucsessfully.

    But my concern is the shape and proportions that are proposed to cast...smallish blocks that are relativly thick in comparison to their size would be much more stable.

    A large flat thing a foot square and an inch thick would be more of a challenge and require some carefull thaught and choice of resins.

    Depending on what he is trying to achieve, there may be better, easier and cheaper ways of acheving it than trying to cast it in one big lump

    These things aint going to be cheap either.....I cant see it taking any less than half a litre of resin.....if that resin is marine epoxy or polyeurathane that will be getting expensive.

    cheers

    Abrasives can be just as dangerous as a blade.....and 10 times more painfull.

    You are absolutely right, Soundman.

    That foot x foot x inch board that you hypothesise is about 2.25 litres gross. Depending on sawdust ratio it could take even more than ½ litre of epoxy - and epoxy is expensive.

    Current prices for the stuff I use (a WEST reverse-engineered) is:


    ½ litre - $25 = $50 per litre
    4 litres - $99 = $25 per litre
    20 litres - $399 = $20 per litre
