On longer mills this upgrade may not effect tapers too much. But the
shorter mills will bind this up, I'm afraid. You should see how sloppy
my Wood Chuck is, never ever jumped a tooth. And I have all the fine
teeth gears too. Hope this does not become a problem for you. Only way
to tell is set it at full taper.

Can the mill still do tapers I have found that I like a bit of slop in
everything in the gears and linkage so there is enough movement for
when you lower one end of the rails to mill tapers.

*Subject:* gear carriage bearing upgrade
ok, so doing some work on the headstock end and saw that the gear
carriage assembly was a bit loose and "floating" around a bit...a
further inspection revealed that the bronze bearings were worn a bit
and that was enough to cause gears to wobble and perhaps,at times, not
mesh properly...some quick measurements and a dive into the mcmaster
book and i could see with just a few shaft collars(3 total) and a
couple of needle bearings, things should tighten up much better than
replacing the bronze bushings...so an improvement was called for...a
little bit of welding, some minimal grinding and the job is
done...total time was 1 1/2 hours, start to finish...the end result is
an incredible difference...the carriage is very tight and does not
move or waver at all...replacing the bearings is a snap, as well, as
split collars were used, although i might expect the needle bearings
to last a very long time...with this mod, the machine is now totally
on bearings(in the process of doing the "Z" axis now), all axis' and
all turning points...sorry for the two bad photos, close-ups just
don't come out well with the camera i am currently using...and haven't
decided what color to paint this one yet, waiting for a suggestion
from curtis...LOL!...anyway, all comments welcome and more mods to
follow...and if anyone should want more detailed info on this mod(like
specific mcmaster numbers, for example) or any i have done in the
past, feel free to ask...thanks...joe
