Hi,

my name is Keith, living in Melbourne, Australia, but originally from the UK (just too damn cold and wet).

I've built a cnc plasma cutting table to compliment my other toys - lathe, mill, bandsaw, press, welders, etc. Hoping to one day turn this large and risky investment into an income producer, instead of an income taker.

One of the things I would like to make is ball / spherical firepits with patterns cut in them with my plasma cutter. However getting hold of these spheres seems difficult or expensive. Mind you if I manage to do one metal spinning thing I'm sure I'll end up thinking of a few more things to do.

Perhaps extremely ambitious but I'm wondering what sort of mammoth lathe I would have to build to try and spin 3mm thick mild steel about a metre in diameter. My metal lathe is big enough to machine whatever shaft size I'd need, it's 1.5 metre between centres.

Keith.
