Dave the only thing that belongs to the Dalton is the cone pulley
on the morfidit countershaft and maybe one of the back plates he
calls a face plate would be usable. Other than the chucks there is
nothing Dalton. I have not a clue as to what that cross slide
compound thingy belongs to but its old rusty and beat. Same for the
milling thingy. Never seen one like this before and sure is not a
Dalton one.

Ok, I'm back.
Would you believe I can't find my test bar? I think It got
misplaced and then used for something. Considering the meagre
space I
have for my toys, it's not that unbelievable. So, I'm making
another
one.
And that leads me to the first question here. How tight should
you
tighten the three jaw chuck? I've been clamping it pretty tight.
Just
short of leaving jaw marks I think. I like to think that whatever
is
in there isn't going to move no-how! Is this bad for it?
And, what is best on my leadscrew? I put some "Super Impact
Grease" on it. This is just real sticky grease. I put it on the
change gears and it leaves little stringers between the gears
while
the lathe is running. But I'm thinking that little metal chips are
going to get on there and the grease will be hell to get off of
the
leadscrew so maybe oil is a better idea?
Ok, the calipers. So, the .001 deviation is anywhere in there,
whether you're in the one inch or five inch range, you could be
off
by .001". And with the micrometer, you're only off by half that or
less. What exacly is the AGG 1500 standard? And, since the 8.00
ones
have to meet it like the 250.00 ones do, I would imagine that the
real expensive ones have hardened and ground threads and the like
and
will retain their accuracy for more than a month? So what about
the
digital micrometers, do they automatically adjust for error? Do
they
wear out too?
All right, enough for one evening. Maybe I should just go bug
one
of the sales people at Brown and Sharpe. Hey Dennis, can I use
your
name so they know I'm legit? =8-O
I'm going to go slather some more grease on my leadscrew and use
it
as an auto feed for me test bar. Thanks for the responses!
Oh yeah, does that Dalton come with an extra cross slide and top
slide or did that guy just take it off the lathe and lay it in his
driveway so he could get a better picture of it?
