Building a New Lathe

<< < (130/171) > >>

S. Heslop:
That's interesting to read. I've heard of it before in the context of bearings and also in a few older lathes switching over to zamak parts, implied as a cost cutting measure. So I was thinking of it in my head as the classic mystery pot metal and not really a useful structural material compared to aluminium. It's low melting point definitely makes it worth keeping note of.

'Chinese metal' appears regularly in such things as vehicle carburetors and in model engineering, the feed nuts on Myfords are a zinc alloy.

One fault is that it does corrode until after a certain point it will be nothing more than white fluff! Chemically, it is somewhat worse than cheap brass.

However, it is easy to cast and I have rather a nice Unimat clone lathe made from -- lots of it.

Probably 'metal' for typesetting is something similar.

I hope that I haven't stolen the original post-- but Simon did ask

That would be Mazak, Fergus.

I thought that I'd written about this - before my world was thrown topsy turvy.

Ah well, it's an absorbing post- thanks
