Does anyone want to build me a cnc router?

Hi,

My son trained as a goldsmith and he made his prototypes from hard carving wax and then sent them off to Birmingham to have vulcanised rubber moulds made. My thought is that wax would solve the dust problem and if it is messed up or just not right, then you can just recast the slab and redo it. Also, if that is all you are carving on the machine it could be quite lightweight, but I still would not advocate Chinese.
Marchant Dice make lightweight machines that might be suitable for wax

.
I recall that wax was advocated to make CNC trial pieces, but nobody seems to do that now, probably because CAD is used more.
.
Just my two pennuth.

Cheers,
Rob

Hi Rob.

Thanks for your two pennuth, it was very useful. i will definitely have a look at that method of carving, sounds very interesting.

again thanks for your input.

Hi Peter,
I am a little bit puzzled as to how you plan to use the moulds again. As the images of the signs you wish to make are (in the second image ) a 'one off' design so unless you can make the number part of the sign changeable then a mould is just extra work to on avail.
So unless I have missed some point, I think it needs a rethink! Perhaps you should think of just doing unique signs, after all you will be doing them just to make a mould.
