Anyone know where to get 'em?
specifically, the tool for loosening the chuck retaining ring (giant C-spanner, I assume) and the internal parts for the drum brake.
for a Mk1 student.
I bought a set of NOS jaws for the Pratt burnerd 8" 3-jaw, which failed to stop it running off-centre. can't see anything wrong with the chuck body and mechanism, and the chuck body runs true. more or less solved by gripping a large ex-bearing race on the outside steps of the jaws and then running a carbide boring tool down the resultant "hole" in the middle. It now runs more or less true.
Is this normal practice, or should I look in more detail at the internals of the chuck?
