Pulled the cover off the gear box..and yeah..wiped out (2) bevel
gears. Im not sure why it did it in the way that it did it. Looks like
something jammed in there..but I cant find any busted pieces of
anything other than teeth. Might have wedged a busted tooth in
there...shrug.

Boston Gear Catalog time. If I order them from Clausing..Ill likely
have to sell a child to pay for the parts. Gonna replace the gear
shifter piece as well..its pretty well worn out also.

Correction..I know why it did it..there is no shear pin on the
powerfeed rod. There is one on the threading lead screw.
After going through the schematics (yeah..I have the manuals)..there
is ZERO clutch for the powerfeed section..which surprised the hell out
of me. Something to watch for in the future. Or modify the machine
and put a shear pin in the powerfeed rod. Which..may be the smart
thing to do.

The gears that swallowed their asses..are on the drive side of the
quick change gear box..not the output side going to the screw(s)

Humph!

A way smarter thing to do: even when you're only working up near the
chuck, roll the blanket all the way off the machine instead of leaving
it draped over the tailstock. Sure, this time your little lathe tent
only screwed up your life for a few weeks. But next time there may be
a garter snake inside that tent, and when he sticks his head out
you're going to fall backwards over whatever crap is laying behind
you, and impale yourself on whatever other crap is piled on top.

It doesn't hurt to give them a call and try to negotiate. After a bit of
fussing they gave me "dealer pricing" as they could't find a dealer near
me.

call clausing and ask, their prices were quite reasonable

Suckage. So, ya gonna drill-'n-pin it? Are those gears sitting on
bearings or splined shafts? If splines, that negates that concept, as
far as those gears go. Looks like a combo, but I can't see the entire
drivetrain.

Easy access/replacement. Since it's a popularly rebuilt lathe,
chances are good that gears A) aren't too highly priced, and B) are
readily available.

Pic 6 (flat-sided round gear) is telling. :/

quick change gear box..not the output side going to the screw(s)

Humph!

Does that cause more work? And does it change your opinion of the
cause of the failure? I love troubleshooting things so I can do mods
which save them from a future (expensive/time-consuming) failure.


I just got back from CA. Too tired, but waved down toward your house.

We got Mom moved into the assisted living place (6 bedroom house with
rooms for 4 seniors with dementia) WHEW, I didn't realize so much
crap could be shoehorned into such a small apartment! 4 people, 2
trucks, 4 days, and we're done. She's happy, we're happy, it's all
good.

I agree, I bought parts from Clausing often.

Iil do that as a control...but IVe found their prices to be
horrifyingly high, which is also the general opinion of others on the
net as well.

Nah..same amount of work. Just really really surprised to find no
shear pin anywhere in the path from the main drive gear to the screw.
Frankly..thats damned poor engineering. Most/many high end lathes
will have at the very least..a shear pin in there, though most will
have some sort of friction device in there. The threading screw does
have a shear pin..but not the feed screw. Suckage!
