I know this has been asked, but I coudln't find any answers when I
searched...

What's the largest diameter one can turn with an 7x12?

I have a project where I need to turn a 6" piece of alum but not sure
if a 7x12 can do it.

Any suggestions?

Thanks.

If the piece of 6" diameter aluminum is of any length (i.e., greater
than that which could be attached to a faceplate), the 7x12 cannot
turn it.
In fact if we are talk about work that must turn over the cross-slide
and be supported by the tailstock, a 9x20 cannot turn it either.
A 9x20 can turn 5" over the cross-slide, and 7x12 can turn about 3"
over the cross-slide. (I don't have the precise number at this time,
but I can get it if necessary)
