Thanks Andy and Ian it sounds like the 7x12 will do the jobs i have
in mind for it so i will be putting an order in soon for iether a
sieg c3 or a chester conquest i think they are the same machine...

Chris, I had a 3.25" length of 1" diam. aluminium handy, so I've
just tried facing it in my 3-jaw, without using undue force to
tighten the chuck. In fact, the chucked end was a smaller diam. for a
quarter of an inch, so the effective grip was on less than 0.5" of
the job. Using modest (3 thou or so) increments, it faced up nicely -
can't see any appreciable light getting through when holding it up to
the window, against a straightedge.Would be a long job, though, if
there was much metal to be removed to achieve the right length, and
a travelling steady, as Ian recommends, would enable more ambitious
cuts.

G'day Moszziesplat.
The job is well within the capacity of the 7x12 lathe. My concern
is
the overhang from the chuck. There is a risk that the work could
skew
in the chuck due to the cutting forces. Being aluminium doesn't
help,
it is softer to hold. If the work was any longer I would
definitely
use
a fixed steady to give support at the work face. Use a steady to
be
sure. Consider getting steadies with the lathe, often they come
as
a
cost effective package.
BTW, with an handle like Mozziesplat and spelling Aluminium
correctly
you must be Australian.
One good turn deserves another.
Regards,
Ian

I'm thinking of buying a 7x12 minilathe but i need to know if
the
standard chucks are cabable of holding 3 inch lengths of 1 inch
round
aluminium stock tight enough so that i can face both ends off.
I would be a complete novice to this hobby hence the simplistic
question.
Could anyone please advise.
Cheers Ian the work skewing due to the tool forces at the end of
the
work were exactly my concerns. What is the maximum diameter of
stock
that will fit through the fixed steadies ... You chaps down in
Australia still spell aluminium correctly like us in the uk, the
reason for my handle is another story that doesnt involve dead
insects on your windscreen/shield?
