The Myford big bore gear train cover has a removable disc to allow long lengths to pass through it. Unlike earlier lathes the hollow spindle does not project enough to jettison swarf clear of the cover. If it goes unnoticed the swarf drops inside to be munched by the gears.

This is my solution, easily accomplished, as my lathe already has the black finish threaded collar shown. There are two opposing holes for a 'c' or peg spanner.

What is this collar intended for and what is the significance of the figures on the spindle ? Manufacturing tolerance or error maybe.

Thank you.

Yes mine is the same Andrew. It looks like you leave off the steel cover disc on yours and run it open. When boring, it easy to forget to remove the disc and in goes the swarf.

I made the alloy cover to provide closer protection around the spindle.

Brian, my previous lathe was an ML7R and the spindle projected far enough through the cover. I never needed to extend it. I thought about the pipe up the hole as you have done. It is easy to get carried away. Sledge hammers and wall nuts.

Regards,

Adrian.
