Relocating Knuckles

[Isaac OLEG]

I can't find a benefit spending so much hours of work to produce
second hand parts.

Unless the flange shape is really something special, or the action is
asking for a particular placement of the roller, I see no real
advantage. Indeed we don't pay so much than you for the parts I
presume.

Best

Actually, David, this is the part of the process I don't get.  I can't
imagine that you can get a nice clean cut up to the shank with a
bandsaw.  I would think that most of the time you'd be leaving a
little bit
of knuckle and core or you'd be taking off a little bit of shank.
Maybe I
just have a ham-handed bandsaw technique.  I'd be more inclined to cut
the
knuckles off on the bandsaw deliberately leaving a little bit of
knuckle
and core.  And then use your jig first to run the shank over a dado
bit
(wider than the knuckle diameter) on the router to clean them up (I
also
wonder if you couldn't just do this to begin with, and skip the
bandsaw
step - sounds a little scary - might be worth a try though).  Then use
your
jig as described.
