Well was working with the Logan a little today, wanted to make a
bushing
for a grinder wheel.
This 4 jaw came with the lathe, and was looking at the jaws, and they
looked like brand new. I thought "wow you got a pretty nice chuck with
this lathe"
I dialed the stock in real nice, within 2-3 mils,was running real
nice,
think it was some cold rolled stock.
anyways, took the OD down a little too far, so I moved the piece out
about an inch to start over, was dialing it in, had it pretty close,
was trying to move it a little, guess I did crank down on it pretty
good, but I thought you should be able to.
Well I heard something snap, and the jaw would not tighten down any
more,just spinning.
There is no name on the chuck that I can see, I have enclosed some
links to pictures. First 2 show the front and back of the chuck,
second two show the broken jaw next to a good one, and the other shows
what I thought to be the jaws looking almost new. The piece dialed in
read nice and straight, and looked like the jaws contacted the stock
nicely.
Sort of seems like a weird jaw, the screw in the chuck does not mesh
with teeth on the jaw, but the screw sort of rides between two notches
in the back of the jaw.
Is this a common style, or poor design, and is there anywhere to still
get a jaw like this. Is it possible this was an old Logan chuck?
Thanks, Tony

Don't know if it will be of any help at all.
But the story is that I have a similar chuck (looks almost identical :-)
Mine is for a South Bend 9"
On the back of mine there are something written in the casting.
There are 4 "hollows":
1: 646-1
2: ?arrow, pointing towards the outside edge of the chuck
3: 5678
4: empty

I know that mine is bought brand new back in 1982 from this company:
http://www.packardmachinery.com/
If they are able to help or not I hvae no idea.

Yeah, Think it was on the Logan FAQ where I read
that...........................Yes here it
is.............................

2.11. Where can I get new jaws or different jaws to
fit my old Logan chuck?

2.11.. Before you buy used chuck jaws sight-unseen, you need to
know that there are hundreds, if not thousands of different jaw
sizes. It is nearly impossible to find replacement jaws for a
particular chuck unless you go right to the chuck manufacturer. Logan
chucks were made by Buck, now Buck Forkardt. Buck Forkardt is not set
up to support home shop machinists. Their prices for replacement
parts are astronomical. It would be less expensive to buy a new
imported chuck than to buy new jaws.

Logan Actuator Co. sells new chucks, made by Bison. These are high
quality chucks, made in Europe and are great investments for your
Lathe.

Don't look good as far as finding a replacement jaw(s). Seems a shame,
as this chuck looks to be in good shape otherwise. would like to get
one of the Bison's, but like I said, I'm not really looking to spend
that kind of money for a chuck.
At this point I did turn the jaws around as mentioned at the yahoo
group.

As JT stated at the Logan group, might be best to "bury" the stock
into the chuck to the jaws are fully supported. If you look at your
chuck, you'll see what he meant.

**Quoted from "JT", Logan Yahoo group**
"That particular style you can ONLY tighten hard if the stock goes
down over
the full jaw length at least. That way the "tab" is being forced into
the
work as well as the rest of the jaw, and the stresses on the "tab" are
less.
If you have to "nip" the stock, it is subject to breaking that "tab"
off."

Might want to consider/thinking about drilling & pinning
too. You have a lot of material to work with on the main
side. This should help with the braze/weld repair.

You might get away with one or two recessed cap screws also.
Two grade 8 cap screws set side by side would be pretty
strong, especially with maybe 3/4 inch or so of threads
caught in the main jaw area.

For drilling & pinning, would I use some drill rod and make the hole
slightly smaller then press it together, then V it out and weld?
Regarding one or two recessed cap screws , are you talking in place of
the broken piece?
This guy at work is a pretty good welder, but he does more like

O.K. I've seen this design used before, usually on fairly small
4-jaw chucks. It has the advantage of being the easiest style of jaw to
make in the home shop, so you should be able to make your own
replacement jaws.

However -- it looks as though this was either cast iron
(machined to size and shape) or hardened and not tempered steel, so it
broke under stress. If you make the jaw of a hardenable steel, leave a
little extra slop in the groves because it will grow slightly from the
hardening process. Then, using a torch with most of the jaw submerged,
draw the temper of the overhangs which the screw bears upon.

Good Luck,
DoN.

I suspect that these are cast iron, kinda doubt if steel
would have broke off like that. Could be wrong (shrug). If
they are cast it will be difficult to get a weld that is as
strong as it was originally, which you broke.

If you try use pins be really careful not to force them too
much or you could crack something else (assuming this is
cast iron). I would just use some steel like grade 2 or 5 in
bolts.

I would be tempted to try maybe three recessed cap screws
something like this (used your good jaw image to show how it
would look when done):

http://www.iserv.net/~lfisk/bkjaw003_idea.jpg

Be careful to observe how much area there is where I made an
orange circle (on both sides). Easy to forget about the
groove. Position the yellow areas so that you still have
plenty of sidewall where you will be making threads.

See what your welder says first, remember you can always
grind and file some if he gets too carried away.

Curious to hear if he (welder) thinks it is cast iron or
not...

I See. I'll let him look at it. I think it might be hard for *me*to do
the drilling, recessing,
tapping and bolting repair, but I think it would be a strong one if I
could do it.
We are talking a pretty small piece that is broken off here. Would
need some awful tiny cap screws.
We do have a machine shop that does make and repair things for us, but
not sure if he would want to fool with it. Maybe I can have him look
at it next time I get to go down there.

You might be able to salvage the chuck by reversing the jaw and
filling in the stepped side with a screwed-on block. I would reverse
all of them and make the blocks out of aluminum, since you know the
chuck isn't suited to heavy work.

Yow, that's amazing! Buck made some VERY fine
chucks that ran to several thousand $! This is
obviously not one of those, however. It looks to
be a REALLY
weak design. If you ever chuck up work shorter
than the depth of the jaws, it
puts extreme force on that lip at the back of the
jaw. I have had several independent 4-jaws over
the years, and they all had a decent length of
half-screw
thread on the back of the jaw, and the screw had a
notched-down section that rode in a ring in the
chuck body to act as a thrust collar.

I've had and used a third design, too. The screw is notched in
the center, but that engages a half-bearing formed by a projection from
the back of the chuck jaw, and the screw travels in a tapped hole in the
chuck body instead.

Enjoy,
DoN.

Thanks again to all.
I think that is "key" here.
I know it's not the best chuck in the world, but it should meet my
needs (light duty, occasional use)
I did not know about the above fact,as this was the first time I had
used it.


Anyway, it appears to be a one-piece, screw-on
chuck, it shouldn't be too hard to find a replacement. *I fear that any attempt to fix that
jaw is going to be a real stop-gap measure that
won't hold.

I would like to find a replacement jaw, but not having any luck.
Any and all leads welcome.

Oh, I think you meant a replacement chuck?
Thanks, Tony
