| but surley nigel.....if you make a mould out of blue tack, that mould will be slightly larger than the original, then by filling that mould and making a resin mould you then go back to the original size, then use that as a mould for the plastic..which will then be a bit bigger than the original size.
yes i know this is picky but on smaller scales couldnt it make a difference?
or am i going on about a load of rubbish? |
