I had forgotten Id scrounged up a Dumore flex shaft grinder some time
back. The handpiece holds a 1/4" tool, which is a bit wierd as the
motor doesnt seem particulary big.

On each end of the actual core of the flex shaft is a .25 x .25 square
crosssection bit of steel that engage the handpiece shaft and the
motor on the other. One of the bits is broken off on one end, so it
wont engage the motor.

Lord only knows what the vintage of this thing is..the motor does run
well, the hand piece has little play or backlash in the bearings... so
it is a keeper if I can fix the end.

Whats the best way to repair the end of the core? Make one up out of
1/4" key stock and tig it to the end of the core?

Any suggestions are welcome

On the topic of Dumore, does anyone know of a webpage with an
accumulation of data on their toolpost grinders? I am wondering how all
the wacky older models that show up on Ebay relate to recommended lathe
sizes. For example the smallest and largest lathe each would be
appropriate for? I have looked around on www.dumorecorp.com but even
the current models have minimal descriptions. Thanks.
