Sheesh, you youngsters G

Bill's quill (I assume he means quill) is too
big to fit through the
hole which leads to the hole he's trying to
bore, so feeding the table/
saddle up will still cause a collision.

Jeez---yes I meant QUILL. Sometimes my
brain/fingers interface gets a little out of
whack.

I can do it with a 7" or so long bar. chunk of
1 1/4 CR, turn one end to 7/8" to fit my
largest R8, slot the other for a single point
tool. No biggy. What I would LIKE is to
have the ease of adjustment the boring head
provides. I may try turning a 1" dia. piece
of 4140 to 1/2" to fit the boring head, and
brazing a tip on the other end. Boring head
diameter is 2", cutter would be around 5" long.
Going to take a while either way---it's a
wallowed out
front pivot hole on a John Deere 4WD tractor
front axle mount.

The idea of turning a long male R8 by male
boring head thread adapter crossed my mind,
but I'm pretty sure the boring head thread is
metric. Possible, but kind of a pain in the
butt
on a 1948 South Bend lathe.
