HI everyone,
Along with receiving a great load of turning timber the other week, a further pleasant surprise was in store. I've also scored a number of lathe chucks. These chucks appear to be an older style to my VM100 however. Better yet, they fit the MC900!
I have no idea what these are called, so I'll try to describe them. I've googled to no avail!
The chucks consist of a body which is around 4 cm long, and threaded to fit on the lathe drive spindle. It's generally cup shaped and has a tapering internal surface, The outside of the body is threaded to accept a collar ring. Between the collar and the body, it would appear that you insert various 3 jaw sets depending upon the job.
There are different jaw sets, the expansion jaws are held as a set by springs, the contraction jaws are loose.
As the collar is tightened against the body, the expansion jaws are spread apart by a conical insert placed between the body and the jaw set. The contraction jaws are pulled together by the taper machined in the body.
So, after all that, if anyone recognises these from my somewhat vague description, what are these types of chucks called, does anyone still use them and are there any hints or ticks in using them? :rolleyes:
