Centec 2A Rebuild
Pete.:
If I'm reading this right the cover pulls the bearing in flush with the outside edge but it has another mm to go before it stops against the seat? That would explain the results you were getting. You would have forever been adjusting the spindle until both cups were fully seated.
Glad you got that sorted.

Success!, you were lucky with the horizontal arbor I had visions of it running out badly.
Mover:
Pleased you got your bearings sorted Paul, also a very good description of your trials and tribulations.
Just one thing, when you mentioned you tried to mount a pice of round bar in your clarkson collet chuck. If it’s an autolock type the tool needs a threaded shank to work. The nut does not tighten the collet but as the cutter screws into the collet during cutting, against the pin in the chuck body the collet is pushed downward against the nut. Self tightening the collet hence the name autolock.

Thanks for that Ross - that explains it, could never figure out how these were meant to work :doh:
Still gonna have to buy myself a new "ordinary" MT2 collet chuck and some ER32's or something, I have loads of plain cutters as well as the threaded ones for the Clarkson.
Cheers,
Paul.

It is possible to grip plain shank cutters in Clarkson Chucks by fitting a threaded and centred plug in the end of the Collet, cut a Screwdriver slot in the other end and adjust to suit .
