Rick,

Thanks for the response and your ideas have clinched it for me. I am
going to get a metal lathe as it spins almost as fast as a wood lathe and
if I need something faster, I could make a wood lathe. Since I also do
work in metric and american sizes in both metal and wood, I think I will
get a new lathe. The old lathes out there are in inches. Turning green
wood is not an issue as all of my projects reuire seasoned dry wood.

Thanks again!

Rich:

It all depends on what you want to turn. Given a decent metal lathe,
you should
be able to turn wood if you just make a tool rest. Of course, if you
turn green
wood, you'll need to do something to protect the ways and cross-slide
table from
the water, or you'll end up with a rusty mess.

I currently have both a chinese manufactured (gasp!) metal lathe and a
couple of
wood lathes, and use each for their intended purpose, most of the time.
My big
wood lathe has bigger bearings on a wider spread than my metal lathe,
(both are
timken tapered rollers) so I do press it into service now and then on
larger
diameter, simple metalworking jobs. I have a cross slide table and
toolpost that
I use with the wood lathe, which has a 3hp variable speed 3-phase motor
and VFD
so I can dial in the spindle speed I want. No thread cutting
capabilities, but I
don't need to cut threads on things that won't fit on the real metal
lathe. The
big wood lathe has a 42 inch swing to the bed, and if I really needed to
go
larger I could unbolt the bed and use free standing toolrest if I was
foolhardy
enough.

I have used the metal lathe for smaller wood (it has a maximum 17 inch
swing over
the bed), particularly miniatures before I got a little wood lathe. It
worked
just fine as long as I was using seasoned, dry wood. Turning wet wood
would be
an exercise in disaster, because I can never seem to get everywhere the
water
can, and the rust would be a problem. Where I live, things rust fast
enough
anyway because the humidity is rarely below 60 percent. The biggest
problem with
using a metal lathe as a wood lathe (besides the rust issue if you turn
wet wood)
is the need to remove the tailstock and at least swing the cross slide
to the far
end of the bed to make room for you to work. If you are only doing
spindle work,
it might not be so bad, but as soon as you do even a shallow bowl you'll
need
access from the end....

One of the best things about having the metal lathe was the ability to
use it
when I built my big wood lathe. I turned the spindle to just under 2
inches
diameter at the bearings (50mm bearings are a lot less expensive than
american
standard 2 inch ID bearings...) plus turned the nose and threaded it for
1 1/4
inch by 8 so standard faceplates would fit. Having the metal lathe
allowed me to
get a substantial spindle for the wood lathe at a decent cost. The
nearest off
the shelf unit I could get would have cost me well over $1100 for the
spindle
cartridge, and I don't think I have that much in the whole lathe,
including the
raw spindle stock, square and rectangular tubing, a 3hp 3-phase motor
and VFD
(Variable Frequency Drive) that will run the 3-phase motor from single
phase
220vac that my shop has.

Good Luck!
