G'day Ren.
I have looked at other's posts and what they say is true but may not
have answered your problem. I read that you are seeing flexing of the
compound and tool post structure. Having the gibs for the cross slide
and compound firm is critical. Obviously you need to be able to move
the cross slide so you can't lock up the gibs for that but you can
make sure they are firm. For the compound you can set you tool at the
right position and then tighten the gib screws so the compound
doesn't move.
I am assuming you have a saddle lock. If not you must stop the lead
screw (gear in neutral) and engage the half nuts. This works if you
use the carriage hand wheel to force the carrage back against the
nuts taking out the slack.
Make sure the tool has sufficient clearance and mount it a bee's
whisker high so that flexing brings it to the right level.
A FORGoTTEN FACTOR is flexing of the work piece. A fly rod ferule
will be very thin and can deform under the tool load; you may be
better off parting some other way or designing a thickened section
with more strength to part through. I have to do this job myself
sometime. My son borrowed one of my rods and jammed it in his car
door so I need to make a new ferule; I have thought about it.
Planning is half the job.
One good turn deserves another.
Regards,
Ian

Good morning guys,
I'm a little lost here.
When I'm parting off a piece and I move the crosslide into the
work, the cutter rides, I guess, downward then "pops" up. The bottom
of the crosslide doesn't seem to be moving, but either the compound
or the tool post does move. I checked and the toolpost seems to be
tight to the compound. Which leads me to believe the compound is
loose. Where do ZI tighten this?
It turned into a major problem because I was making a ferrule for a
fly rod and the piece got all bent to heck and is now completely
unusable.
Thank you,
Ren
