Item B2249108 for Scroll Chuck 1X 8 TPI at $65.00 CAD and B2249134 for 3/4 X
16 TPI. In the US it would come to about $50.00 USD.I have one and it does
the job good. These are low cost build in China and sold as no name the
world over. The quality standard is almost none existant. It reminds me of
the AK riffle low quality but it does the job well.
One point is that the two locking (Tommy) bars are made of cold rolled
steel. They do not bend but the edge at the end of the bars will wear out a
little after a year of use. I would replace them with the right size drill
rod.

Last August, as I was getting started in turning, I bought a cheap 4-jaw
chuck with a grip range of about 2-4" and Tommy Bar closure. I'd like to
buy a couple more but don't recall where I bought the first one (online).
I
paid about $50 for it, despite being warned off cheap tools and find that
it is more than adequate for what I am doing.

It IS cheap ... there doesn't seem to be any manufacturer identification
on
it so I can't even search for it with that term.

Any clues, gang?
