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.

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?
