Good Morning Gents
I've another new guy question ¨C
Before I get to it, thanks to all of you who've been kind and
patient with my previous inquiries ¨C while I'm sure they are
elementary to you folks, they were a bit daunting to me ¨C I
appreciate your kindness and patience.
O to the question ¨C I've gotten to the point that the 3-jaw Union
Chuck that came with the lathe is now the weakest link in the
accuracy chain (previous weakest link wsa me ;-} ).
The scroll and backsides of the jaws are very worn (no surprise ¨C it
doesn't look much younger than the lathe), and it's only in the
accurate ballpark at one diameter setting (darned near maxed out).
I've decided to spring for a decent 4-jaw chuck ¨C I read, with
relief, though the spindle threads on these old nails IS oddball (I
was scratching my head wondering why I couldn't seem to find a
commercially available chuck that would mount up easily).
Is there a reason I couldn't use the back plate off the Union chuck
to mount the new 4-jaw?
Also, among the rusty greasy bits that come with the latch is what
appears to be a spare back plate. It mounts on the spindle very
nicely, but the flange (is that the right term?) is thicker that the
one on the Union chuck, and is not drilled for any mounting
hardware. Could THIS be used to mount the new chuck?
Lastly, I've seen references on the board here to getting a back
plate and doing the mounting to the chuck on your own lathe. While
this makes sense (getting maximum accuracy), I have no idea how to
go about doing this . . .. any pointers?
Thanks, in advance, for any assistance you may be able to render!
