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 . ;-)

Subject: Tapered Barley twist revisited
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?
