Hi Guys,
Late input!!!.
When cutting threads to a face either by
screwcutting on a lathe or using button dies, which still has a
thread lead on both faces, the only
way to ensure that the threaded portion will
allow seating to the flange face

I've been travelling, hence the delayed reply. However, others have

I have done a lot of research on machine tools for my model shop. I have
examined the Central machine lathe closely and do not believe it to be v
It's not only the ability to cut threads, It also means you have power feed
and this is important to get a final finish on a turned part. As much as you
can practice, you can't get the same finish with hand feed.

is by undercutting
Weigh your personal needs for the thread cutting abilities. Not everyone needs
the threading ability but it's one of those things that if you need it, you need
it.
Threading up directly against a shoulder is certainly a good example. Cutting
oddball diameter to pitch is another that comes to m
Now wouldn't it be nice if Charlie would give some instruction at Diamondhead
this January - even informally.

FWIW, I have both the Taig (with the Sherline motor for infinite
for small diameter, fine thread screws, you can thread up to the head in the
normal fashion, then take the die off, 180 degree it, and carefully finish
the job. NOT considered good machining practice, but it can be done!

Vance:
Cutting shoulder bolts, I assume you're not cutting to the head so stopping
short shouldn't be a problem. If you need to get real close, cut the
threads the way you normally would with the die, remove, reverse the die and
cut again. You're doing this by hand turning the chuck so you can
Hi Paul,
I have recently purchased a second hand Sakai lathe. This has a couple of
problems that are causing me some grief.
Firstly, check that the tailstock takes a full length Morse taper
(preferably a MT2 minimum), otherwise anything you get will be a problem.
The Sakai has only room for a
Paul,
I am not sure what your reference 7/10 means and I don't know what the
Central lathe looks like, but I think it is similar to the Grizzly Chinese
lathe that has variable speed, thread cutting, and a rotating tool post. I
have one of these, a 6" Atlas, and a small Unimat.
What you want to l
Keith, I agree that dies are what we need most of the time on this tiny stuff,
but there are a couple of instances I can think of where using a die could be
problematic. The first that springs to mind is making shoulder screws for
attaching side rods. Can you do that kind of partial threading

Pretty good conjecture Kevin. When I bought my

I have had a Taig for five or six years and have enjoyed it, but it's pretty
limited IMO. I am seriously considering the Enco/Harbor Freight table-top
lathe at the moment because I having a devil of a time turning flanges on 1-

I've been really happy with my little Taig lathe. I'm not anywhere near an
experienced machinist, but the Taig is very easy and straightforward for a
"complete beginner" to use. There are a good number of accessories for it,
and I'm sure someone who really knows what they're doing could do some

I am thinking of purchasing a small lathe and have narrowed my search to
two . the first one would be a Taig Lathe with a 1/4 horse motor .
the second one would be a 7 / 10 inch lathe Made for Harbor Freight by
Central machine .
Both would run about 400.00 dollars .
the Central has a lead screw
