Did this chuck work? I can't find it on Grizzly's site. What's the part
number or link? My only concern is what's the swing of the whole piece and
does it need a drawbar to stay in place? The legacy is not designed to pound a
2mt object into the headstock. You have to be nice to the socket :-).

@ cole...but what if you want to back out that 1" router bit a bit because it
better suits the finished look you are trying to achieve?...let's say to
7/8"...the whole mathematics thing is not usable...i found a grizzly piece that
i think will be a nice add-on piece to the legacy and let you index to any cut
you want...any repeat from 1 to 360...it will be here in my shop tomorrow and i
will begin the not-to-difficult process to modify it to fit the legacy...see
attachment...there are 15 degree indents built into the chuck(24
divisions)...the chuck is 3" in diameter...and it has a #2 morse taper...should
be interesting if i can pull this off...thanks for the reply...joe

You move the router the diameter of the bit. Say you have a 1 in. rope
bit ,you move 1 in. forward or back it does not matter reengage the
router so you can crank it back to the original starting position. you
will automatically be ready to do the next start on your twist.
