If you are drafting an adjustable tail stock, Use a screw adjustment so you can
get real fine adjustment on many different angles.
If you are going to Dream, DREAM BIG! ;-)

You know me, I'm already drafting at tilting offset tailstock that replaces
the stock one :-). Can you take a picture of yours when you get a chance?

I drill a 1/4" hole and use a cone point live center. Just use a board
with a hole drilled to hold your live center secure and clamp it to the top of
the existing tail stock. That will be one of those temporary fixes that become
a permanent fixture in your shop.

OK

Hi Curt,
Look again, it was 2.5" diameter on one end, 8 degrees total taper , 4
degrees per side (the max taper on a model 900). I don't know about the rest
of you guys, but any angle past 2.5 degrees and my gears lock up and the
adjustable arm starts to bend. Definitely want to see your offset jig. It
reminds me of the mod Bill when he made his side cutting router. His tailstock
was able to be offset to get a good taper going. I'll have to go look at that
again.
Hey Mike, my chopped legacy can go to 9 degrees (18 total) but the gears
will not work at that extreme angle. That is why I thought about your
universal joint idea. How do you hold the tailstock end?
Thanks guys,
-Tim

Hello Tim
8" on one end and less than 1" on the other, Unless you have a straight
bit 7" long cutting horizontally would not be possible. but I think It can be
done.
As you suggest cutting from the side and with the use of a template
would work.
How about thinking outside the box. (so to speak.) make a turning on
the lathe, and then make an off-set on your legacy to hold the part straight so
that you can turn the barley twist. I made an off-set jig a few years ago. it
mounted to my table (my machine is mounted on a table, I do not have the leg
set.) the live center was lowered so I could get the angle I needed.
I will find my jig and take a picture tomorrow.
I hope this idea helps?
Its past my bed time.
See you all latter. 03:30 tomorrow . ;-)

Hi Mike,
I'm revisiting this old topic and ask if what I'm thinking of doing
is even possible. Take a look at the attached drawing. It's a tapered barley
twist made with the magnate 7554 Barley twist bit and 1.5" of pitch. I need to
over come the gears locking up with the full 4 degrees of tilt, but after that,
does the piece have a chance of looking like my drawing?
I was thinking of using your universal joint trick to get more angle.
Otherwise I think my only other alternative is routing from the side with a
straight cutting bit a template and some handwork. Do you think this can be
done on the legacy?
