I have an old procunier tapping head that I got because someone forgot
to oil it. That was about twenty years ago. I repaired it and it ran
fine until about 10 years ago when the cork clutch lining broke loose
from the aluminum center piece. 5 minute epoxy worked to put it back
together. Today it broke loose again. The procunier web site sells a
new clutch assembly for 58 bucks. I just re-glued the cork back on the
center piece. Bet it lasts another 10 years.

I suspect if you used a more resilient adhesive, it would last
forever. Maybe something like gasket sealer or contact cement
would be the best.

The problem with mine was some imbecile filled the thing with
WD-40! I got a "CNC" model 15000 head on eBay. It ran real
hot, so I opened it up, and got DOUSED with WD-40 with graphite!
Yuck! I have to clean it out every year or so, when more WD-40
oozes out of wherever it is hiding (maybe in the cork) and the
clutches start slipping again.
