Anyone have good pointers to where I can get a 6" scroll chuck with an adjustable back
plate? I know Buck makes one, I'm not sure what chuck we have on the LeBlond at work but
it is sweet being able to dial in concentricity. I'm trying to find the best deal on a
good chuck.

I need to get this accessory purchased soon. I just heard that the AG for Michigan may be
lifting the disability to own suppressors in my state soon which would divert my metal
working budget to my gun budget.

Buck is the name brand. Bison has them too. I happen to know a cheap
skate that just made his own, Not that hard a job.

Personally if I were to buy a new chuck I would just buy one that has
removable top jaws--be careful truing your backplate and it should run
within a thou or so which is fine for most work, that way if you have a need
to be dead nuts you can always put in a set of soft jaws and bore them.

Besides, adjust tru chucks take will vibrate quite a bit unless you have the
chuck body running close to centerline and they take just about as long to
dial in as a 4 jaw which negates much of their supposed advantage anyways.

I'm GWE on you getting ability to own a suppressor. Done deal from

They are legal here where I'm at but I fail to see any legimate purpose for
them especially considering that the attendant permitting fee is ~$300.00...

But since tax revenues on cigarettes is on the decline then might as well
take advantage of gun owners I suppose.

If you are after *new*, look at Bison chucks. Nice quality for
reasonable prices.

If you already have a good 3-jaw chuck with a separate
backplate, it is possible to adapt it to make one with an adjust-tru
style feature.

1) In preparation -- turn a chuck of steel to the OD of the chuck
and backplate, and then bore it to leave perhaps a 1" thick
wall.

2) Remove the chuck from the backplate, and drill and counterbore
the ring from (1) above to accept screws into the back of the
chuck to mount the ring firmly to it. You may want to set up
dowel pins so the ring can't shift relative to the chuck body.

3) Drill and tap the ring to accept screws through the backplate
holes a bit oversized into the ring. If you use the dowel pins
mentioned in (2) above, probably you should drill and tap these
holes all the way through the ring so you can use longer screws
as jackscrews to separate the ring and chuck body in the future
at need.

4) Bore a pocket in the backplate perhaps 1" smaller in diameter
than the ID of the ring.

5) Turn a plug of steel to be a snug fit into the pocket and to
project perhaps 3/4" or so into the ring -- maybe a full 1" if
there is sufficient clearance in the back of the chuck body.
Drill and counterbore it, and drill and tap the backplate for
screws to secure the plug rigidly to the backplate.

6) Drill and tap four radial holes for heavy setscrews at 90
degree intervals around the ring.

7) Grind the ends of the setscrews flat.

8) Assemble the whole thing, with the setscrews loose, and the
screws attaching the backplate to the ring sort of tight, enough
to keep the chuck from slipping down to whatever side is down at
the moment.

-------------------------------------------------------------------------------

9) Chuck up a piece of stock the diameter of what you are going to
work with at the moment.

10) Tap the chuck so it is moderately close, and then lightly adjust
the setscrews to touch the plug of steel.

11) Now, using the setscrews and with a runout indicator, adjust
for minimum runout as you would with a normal adjust-tru style
chuck.

12) Tighten the screws securing the backplate to the ring and
recheck the runout, as it may shift a bit with the tightening.


When you shift to a different diameter workpiece, slack the
backplate screws and go back to (9) above, skipping (10) except
for the first setup. (This is why the dividing line, to
separate the *making* from the *using* part. :-)

Good Luck,
DoN.

A couple things come to mind.

The price of Bison chucks has gone way up over the last several years,
and aren't quite the bargain they used to be. I think I paid around
$375 for my 6" Bison 6-jaw; current Enco price is $884.

The lower priced Buck chucks (BVC, I think) are overpriced crap. I
bought one recently that a customer specified for a job and had to
disassemble and refit the jaws. My customer said they do that to most
that come in. Might as well buy a Chinese chuck at half the price. The
cheap Bucks probably *are* Chinese. I do own one small Chinese chuck
mounted on a 5C arbor that came in an auction lot. It's actually not
bad.

I have a couple adjust-true type chucks, but don't recall the last
time I tweaked one. I'll almost always use a 4-jaw instead.

Just buy a four jaw independent chuck and learn to use it. I use a

three jaw chuck.other than a drill chuck on other than my Unimat 3

I'm doing most of my work with an 8" 4 jaw unless it fits my collets. The 4 jaw has
serations in the jaw that makes it hard to use for small things. I wish the jaws were
smooth.

Greetings Wes,
I have been turning parts for about 35 years. On all sorts of
equipment. I use almost exclusively three jaw chucks that I have
modified to be adjustable. Using good chucks they repeat well and
adjust MUCH faster than a 4 jaw. I know, I know, folks say that when
you learn how to use a 4 jaw properly it's just as fast as an
adjustable chuck. Not for me or anyone I know. For work that has to be
adjusted less than .020" an adjustable chuck is the way to go. And I'd
spend the money getting a good plain back chuck and making it
adjustable rather than spending the exorbitant money they charge for
them. Jest my 2 cents.

Aww okay I see now that you meant for noise suppression, not flash...I

not...let's have a look...

I probably would hardly notice even if you were firing a 50 browning next
door but unless you really had a really good layout on your property you
would likely just do like several other locals and come over here to shoot
instead.

We use disposable earplugs or the Smith & Wesson blue earmuffs which I'm
pretty sure came from either MSC or McMaster of which there are several
pairs in the shop.

One neighbor did complain about noise a few years back though--the Sheriff
stopped by and let me know that he basically told her if she is truly upset
by the sound of gun fire then she should probably move back to the city.....

Then you may want to compare the Buck and the Bison. There are more
and deeper serrations in my Bison 6" six-jaw than those in my Buck 6"
three-jaw. The Buck is an older forged steel chuck, and hopefully my
criticism of the economy Bucks doesn't apply to the current steel
chucks. And, as I mentioned, the price spread between Buck and Bison
isn't nearly what it used to be.

You might also want to keep an eye on this ebay seller's auctions:
http://www.ebay.com/sch/toolmexonlin....c0.m270.l1311
They show up occasionally in one of my saved searches and seem to have
good prices on Bison chucks that have been returned or were dinged in
shipping.

I also fail to see a need for them here. I'm not even sure
whether Virginia allows them or not, and I have no motivation to check.

If they were not so expensive to legally own, I might be
interested in making one or two to see how they work -- and how well
they might be made to work -- but after that I would not see any reason
to keep them once the experiment was done.

no back plate. It came from Enco, no doubt from a sale flyer, but
that's still a big increase in 8 years.

After the comments on Buck, I'll look at Bison.

Call these people and inquire about a good used bison or buck chuck.

Don't mean to be a smart-ass, but could someone
tell me the advantage of a 3-jaw chuck that you
can dial in verses a 4-jaw independent chuck.

It seldom takes longer than 2-3 minutes for me
to dial in a 4-jaw chuck to .001". I have a
dial indicator and base all set up and seldom
use a 3- jaw chuck any more. Am I missing
something?
Greetings Jim,
I do a lot of work that has to run true better than .0005". When I
dial in a part in the 3 jaw adjustables it repeats better than .0005"
at that diameter and chucking pressure. When I change diameters and
need to re-adjust the chuck it almost never takes me more than 2
minutes. HOWEVER, if I had only one chuck it would be a 4 jaw. Lots of
the time I bore jaws, and three jaw chucks with top jaws make that
real easy. None of my 4 jaw chucks have top jaws, but I'm sure they
can be had. BTW, I bought several years ago a 4 inch chuck on a 5C
arbor. It is Chinese made. I was unable to find one that wasn't. I
took it apart and made it adjustable. The jaws were all in the same
plane and perpendicular to that plane but the back face of the chuck
was not perpendicular to the jaws. I tightened the jaws onto a just
turned spud and machined the back of the chuck true. Then I modified
the chuck to be adjustable, with only 3 equally spaced screws instead
of 4. It repeats better than .0008". And adjusts fast, but not as fast
as 4 screws.
Cheers,
Eric

I do not have a 3 jaw chuck that is adjustable. But what I think is
the advantage is in production. You can adjust a three jaw once and
then machine a hundred parts without having to spend that 2-3 minutes
per part.

You can do that with a 4-jaw, too. If you torque all 4 jaws to the same
torque, only loosen two jaws, are using the same o.d. workpiece each
time, and re-tighten those two jaws to the same torque as before, it's
every bit as true as a scroll chuck would be.

It's in the maneuver, not the hardware.

Besides, only collets are accurate on every chuck-up.

For a single workpiece -- none.

For multiple workpieces of the same diameter (e.g. production),
it repeats quite well (though not for workpieces of differing
diameters, where it is at the mercy of wear on the scroll and the
"interrupted threads" of the jaws.)

It seldom takes longer than 2-3 minutes for me
to dial in a 4-jaw chuck to .001".

And is about the same dialing in an Adjust-Tru style of chuck.
But you only have to do it once for a run of however many parts you want
to make in one setup.

I have a
dial indicator and base all set up and seldom
use a 3- jaw chuck any more. Am I missing
something?

Production work -- where time per part is more important than
set-up time.

Of course -- for enough parts, soft jaws bored to size can be
even better -- especially if you need a step against which to set the
part for depth control as well.

Enjoy,
DoN.

The big advantage of a 3 jaw that you can do adjustments on..is when you
do repeat parts. If you are only doing (1) part..a 4 jaw works just
fine..if you are set up and practiced at doing the setup.

Gunner, who has a big choices of 3/4/6 jaw chucks..and some are Adjust
trues.

Greetings LLoyd,
With a 4 jaw you at least need to tighten two jaws. With a three jaw
only 1. And accurate 3 jaw chucks will repeat better than .0005". If
it was true that the time difference was practically nil then
everybody would use 4 jaws almost as much as 3 jaws. But for even a
few parts a good 3 jaw is significantly faster than a good 4 jaw.
Eric

--Unless you spend a LOT of time on the lathe you prolly don't need
one. I do a LOT of lathe work so I've got a 4-jaw and I also have a 6-jaw
Buck Adjust-tru. Turns out I use the Buck most of the time. For irregular
shaped work I can leave a jaw out and sometimes it'll work. For square stuff
I use a split bushing to center it and the advantage of 6 jaws really
shines. Also the jaws on a 6-jaw chuck are much pointier so I can hold stock
as small as maybe 3/16" dia without resorting to collets.

Very well stated.
