I cannot find anyone on this forum who had
critisized a bit of HSM magazine - all the
comments so far have been glowing.
I regret to say that I have to keep the tone
of the discussion at that same level though.
I received my copy of HSMDYWCBIB magazine
this weekend and must say that the article
on chucks was the most comprehensive discussion
I've ever seen anywhere in print. I especially
felt for the poor man who crashed his brand
new 6-jaw! It should be required reading for
anyone who is purchasing any kind of lathe, new
or used.
The only possible addition one could make would
be the caveat that nearly every single scroll
chuck that is included in any used lathe purchase
is probably either a piece of junk that should
have been left behind when the machine was taken
(seller kept the 'good' chuck for himself), or
is a barely adequate piece of tooling that has
been crashed many times in its past.
Either way, the most common theme that new lathe
owners post questions about seems to be, "How
Come My Chuck Won't Center Better than Fifteen
Thousanths?" [1]
0.015 TIR for a worn-out piece of tooling really
isn't that bad - which is the unfortunate answer
that many times has to be given.
Which leads one rapidly into a discussion of
"How Come Collets Cost so Much" and "How *Do*
I Center Things Up in a Four Jaw?"
I suspect the next article in the series gets
into some of that.
I'm eagerly waiting
for it!
Jim
[1] and the invariable follow on, "Can I Use
a Dremel Tool to Grind the Jaws on that Chuck?"
Short answer: "It's a waste of time."
