One gizmo is a C-clamp kind of thing, with a twirly handle and little

looks like polished nails with flat ends, 4 different lengths. Another one
is in a red plastic case that says "Bluepoint" on it, but I don't see any
points or anything blue. Bunch of short, heavy black metal tubes of
different sizes. But it has 5 bids, and about ready to end. Can't figure
out why anyone would want this but if you think you can use it better be
quick.
Then there's a wooden box with metal rods in it, a label in the box says
"end measures". What the...? Looks pretty old, like it came up from a
pirate ship off the bottom of the ocean or sumptin'.

Oh crap. I thought they were centerpunches. Ah well, maybe someone
will outbid me. I've got plenty of those numbered C-clamps so I didn't
bid on that one, though.

According to Ken Grunke :

[ ... ]

Obviously, based on the auction listing, you know more than you
let on in the article here. ;-)

Then there's a wooden box with metal rods in it, a label in the box says
"end measures". What the...? Looks pretty old, like it came up from a
pirate ship off the bottom of the ocean or sumptin'.

Hmm ... from that auction:


================================================== ====================
The set includes (3) 12" measuring standards, (2) 6", (2) 3", (2) 2",
and (2) 1" standards, plus (1) Brown & Sharpe micrometer head which is 3
5/8" long fully retracted with a 1" range.

There is an empty space for a 12" measure, and a bore micrometer but
these are not listed on the inside tag so looks like they were never
included originally.
================================================== ====================

That "bore micrometer" empty space was for a second micrometer
head -- later sets have them with different color collars, so you can
set a minimum and a maximum size at need for tolerance work.

But -- in any case, the label *does* show that there are
supposed to have been two micrometer heads, though there is a place
stamped for the number of 12" rods which does match what is present.

It would be nice to see indications as to whether both
micrometers are calibrated only in 0.001" divisions, or whether they
have a vernier for 0.0001" readings.

Good Luck,
DoN.

Thanks DoN.
I was a bit confused about that 2nd mike deal, and glossed over it in my
impatience to get the listing up. I figured the pics would give the story.
Wouldn't you agree that the empty space held a bore mike? Sure looks like
it to me.
BTW, for anyone's info, the existing mike spindle does have tenths
divisions. They're actually visible in the bottom right image (closeup C),
but the thing is upside-down which makes it confusing. Another bit of
carelessness on my part.

The Pratt & Whitney thing is a set of end measuring rods for positioning
a jig borer. The reason for the two heads is to accomodate both the x
and y axes. The collars on the heads and rods keep them in alignment in
the troughs described below. I can't imagine using them as inside mics,
except perhaps just the mic heads themselves for a very limited range.

I swiped this quote from...

http://www.practicalmachinist.com/cg...ltimatebb.cgi?
ubb=get_topic;f=8;t=000036;p=0

....which does a better job than I could of describing their use:


"The Pratt & Whitney and the Fosdick used the end measure system. It is
the same system that can be installed on any machine. There are troughs
laid along the X and Y axes. There is a fixed stop on one of the moving
or stationary members and a dial indicator on the other. Cylindrical end
measuring rods of whole inch lengths are laid in the troughs along with
a cylindrical setting micrometer gradated in "tenths". The moving member
is then carefully moved so as to contact the rods and micrometer and
bring them up to the indicator so that the idicator, also graduated in
"tenths" reads zero. This is done for the initial setting. All
subsequent settings involve either adding or subtracting end standards
and rsetting the micrometers for fractional inch settings. The machine
is "In Position" when the dial ndicator reads zero."

thanks - I had it explained to me and then I went on vacation and
forgot everything - I guess memory is the second thing to go....

meanwhile - if anyone wants a set of these, I'd trade for an aloris
brand BX sized cutoff holder and maybe a knurling tool, or ???

Well now Ken, I'd say your auction is perfectly descriptive and the
items are nothing special, especially that second one. Y'all don't
need to look at it or bid against... er, yeah. Nevermind.

Note to the humor impaired: I'm joking. I'm bidding on the second one
and am not attemtping auction-tampering. Sheesh.

If I don't win the auction for Ken's, (already had decided that my max
bid is as far as I'll go), let's talk. I've got a lot of stuff I also
don't use, maybe there's some overlap.

Wow, first time I've had an outside channel with a bidder Dave, I
swear, this item is worth HUNDREDS, it will be a STEAL if you only bid
$150, take my word for it!

Now I know what this set is for, I have a twinge of regret for listing it.
If you get my set, maybe Bill can use a fancy numbered C-clamp in trade
for his?

impatience to get the listing up. I figured the pics would give the story.
Wouldn't you agree that the empty space held a bore mike? Sure looks like
it to me.

It held another mic head just like the one which you have in the
auction. I have a similar set, but with both heads and all two of a
possible four 12" rods. The listing on the label is:

2 Inside Micrometers
2" 1" rods
2 2" rods
2 3" rods
2 6" rods
2 12" rods

"Inspected 4-12-53" stamped into the plate. Two blank spots for
"reinspected" dates. All the parts were wrapped in protective paper
when I got it (at a hamfest).

The "Inside Micrometers" are not intended as bore mics, but in
combination with the other rods in something like a jig borer. The
rods, and one micrometer are laid in a V groove between a fixed stop and
a dial indicator. One or the other is attached to the moving axis, and
the other is stationary. So -- you can make a hole in a particular
location, zero the dial indicator, and put into the groove a combination
of rods plus the micrometer head. Then you move the axis until the dial
indicator reads zero again, and you know you have moved a precise
distance. Much more accurate than a (possibly worn) leadscrew. They
are probably being retired mostly because of the accuracy of available
DROs these days. Exclusive of the micrometers, you have three feet of
total range with my set, and four feet with your set. Though, since
these are supplied in pairs, I believe that the intention was to have it
supply offsets on two axes at the same time.

The micrometer heads in my set have a colored sleeve between the
lock ring and the stationary end -- red on one, green on the other. The
sleeves are Phenolic, I believe.

Note that each of the rods has an increased diameter about 1/3
and 2/3 of the way between the ends, for minimum sag, and to make sure
that the center height of all of the rods and the micrometer heads
(which they call "Inside Micrometers" are all the same when resting in
the V channel.

BTW, for anyone's info, the existing mike spindle does have tenths
divisions. They're actually visible in the bottom right image (closeup C),
but the thing is upside-down which makes it confusing. Another bit of
carelessness on my part.

O.K. I would have to go back to the auction to check.

I see it now. I had not even seen those images before, because
they are to the right of the main image, and I had the image size scaled
up to 150%, which pushed the thumbnails off the right side of the
screen. The satin chrome area of the micrometer on yours is where the
colored sleeves are on mine. Perhaps the sleeves are only supplied when
there are two micrometers in the set.

What about on the barrel of the Tubular Micrometer Co
micrometer? (Later called "Tumico", and even later "Scherr Tumico".

I like the flexibility on your payment options. I, personally,
won't deal if I have to use PayPal, so having other options is nice.

I am tempted to bid on the Tubular Micrometer, just to have one.
I have that size range covered anyway, and some later micrometers made
by Scherr Tumico, but not with the tubular frame that this one has.

Good Luck,
DoN.

DoN, you are right about the P&W set being for a jig borer, see Ned
Simmons' previous post. I also remember reading about jig borers in one of
Guy Lautard's bedside readers.

I think you are asking if the Tubular mike has .0001" grads? Nope, sorry.

I'm curious if the hollow frame on this C-clamp is beneficial, or
detrimental to accuracy, as far as heat absorption goes.

Take care,

Ken

Yep -- I was. If it did, it would add accuracy in part of the
range covered by other mics. (I've got tenths verniers only on the 0-3"
range, beyond that it is only in 0.001" readings.

I'm curious if the hollow frame on this C-clamp is beneficial, or
detrimental to accuracy, as far as heat absorption goes.

I think short term beneficial, but beyond that, I don't know.
You grip it on the flats, and the thermal expansion would be about equal
on the opposed flats, and would not conduct too rapidly to the edges, so
they would be fighting each other during the short term, reducing the
total expansion.

The thinner walls would heat up more quickly than a solid
forging would, however.

And these don't have the insulating grip pads which more modern
mics tend to have, so unless you added your own, that would be a
negative.

The major benefit is greater rigidity for a given weight, so it
is less likely to spring with reasonable feel.

Of course, the interchangeable anvils means that it probably
can't be as accurate as a single-range mic anyway. (I've got a Starrett
interchangeable anvil one which covers the 8-12" range, which then
forced me to get mics in the 6-7" and 7-8" ranges to fill in the gap
past the nice boxed set of B&S mics.

Good Luck,
DoN.

If you wanted to cancel my bid and remove the auction, I would have no
problem with that. At all. As a seller you can cancel bids; as a
buyer, retracting a bid is more complicated. By all means, if you'd
like to keep it, and if I'm the only bidder (I think I am), I don't have
a problem with that at all. Like I say it's to fill a gap for a
measurement tool I don't have, not something I actually _need_.

Dave

well, only about two months after the fact, I listed the gage rods I
have on e-bay - I decided that the chance that I'd need them is pretty
small - here's the link:

http://cgi.ebay.com/ws/eBayISAPI.dll...tem=7618581091

the set is marked as being End Measure Gage Rods for Devlieg
Spiramatic Jigmil. The rods in this set are marked to a precision of
a ten-thousandth - I wonder if they are really that accurate? anyone
know???? oh, and the micrometers in the set are sealed in plastic,
so I think this set is usable, not trash like some I've seen.


I also listed a couple of other things that might interest the group,
but this one is the most likely to strike your fancy:

Large Hydraulic Cylinder, aprox 15" long 3 1/4 diameter
