I have inherited handful of old HSS cutoff blades. Would like to
sell all or some.

The first batch are "Luers Patented Cutoff Blades" manufactured
by Empire Tool Company. Sizes given below are widths. The
dimensions given are the width at the working end and at the
tail, the height, and the nominal length. Most of them do not
seem to have ever been on a lathe.

Qty Descrip.
4 No. 9M
.250-.197 x 1.120 x 5 1/2
.258-.208 x 1.120 x 5 1/2
.247-.208 x 1.116 x 5 1/2
.285-.285 x 1.112 x 5 1/2

1 No. 8M
.192-.140 x 1.122 x 5 1/2

2 No. 5M
.233-.231 x .870 x 5 1/4
.158-.160 x .856 x 5 1/4

1 No. 4M
.151-.114 x .777 x 4 3/8

The next 4 blades all have been used and each has one or
another kind of "special" grind (V-grooving, U-grooving,
chip breakers, etc....)

3 Pratt & Whitney No. 0 x 1/8
1 Pratt & Whitney No. 0 x 5/32

Plus a couple of what might not be cutoff blades at all. These have a
cross sectional shape very much like a Lufkin No.902 (I dunno what THAT
is, either, but I have a pair of 'em in their original box. Any info?)
1 pc. is .192 wide x 0.739 high x 4.31 long
1 pc. is .223 wide x 1.100 high x 5.50 long
Both are square on one end and have 20 deg. "clearance" on the other.

Please make an offer on all or any by e-mail to
"pkgloger at yahoo dot com"
or leave a message at 413-443-2827. I'll call back.

Thanks,
Paul (Gloger) in Pittsfield (MA)

No response to my "For Sale" posting. Can anyone help me PRICE these
things? They're just toooooo big for my lathe (7x12 -- a nice toy), and
I'd really like to find them a home. I could Craigslist them if I had
any idea of their value.
Thanks!

Those are made for a huge manual lathe. I hate to say it, but to me they'd
be worth about $20 a ton.

The cool thing about craigslist is you can post on there for free. Pick a number
that you're pretty sure isn't too high, and post it. Mention "or best offer" in
the body of the ad, and don't write the ad to sound too forbidding. The idea
is to hook someone into a dialog and getting them to make you an offer. You
can always repost it later at a lower price.

Or ebay them for .01 starting, and let the market price prevail.

Or just throw them in a drawer and wait until someone is standing there and
sell him one for a buck when he gasps in admiration.

You aren't going to get much for them. Don't waste much time on it.

I don't have a Lufkin catalog handy, but I'm guessing that what you
have may be shaper hold downs. Used also with milling or grinding
machines, to hold down thin parts.

Nice catch, John. Now tell us how the heck they work.

Hmm ... that depends in part on where these angles are present.
If the angles are truly at the *ends*, then it is more likely to be some
form of parting tool.

The shaper hold-downs have both ends square to the length, have
one edge thick (sort of like the T-profile parting tools), but the edge
is higher on one side than on the other. and then tapers down (away from
the higher side) to a fairly sharp edge at the other.

And -- these always come (and are used) in pairs.

I've got only one pair of these (by Starrett) which happen to be
a good match for the size of my 7" shaper.

There is also something vaguely similar, except with a lot of
diagonal slits separating it into fingers which is designed for gripping
thin non-magnetic materials with a magnetic chuck in a surface grinder.

Enjoy,
DoN.

I'm not John, but I have a set of these and use them from time
to time. Lets try some ASCII graphics (view with Courier or some other
fixed pitch font to avoid distortion):

--+ -- vise jaw
|______ +-----------
|\ \___________________ |
| \ ___________________ | Workpiece
| \___/ |
| ^ |
| +-- hold-down |
--+ +-----------
----------------------------------------------------------------------

There is a second one of these on the other side of the workpiece. The
force against the edge of the angled back first causes the sharp edge to
bite into the workpiece, and then to apply a downward force. (Normally,
the wider area will be resting on the vise bottom and the workpiece will
be thinner, but I drew it as I did for ease of drawing.

Usually, the thinner area is angled down somewhat too, so it is
touching the bottom of the vise at the same time as the thicker back
edge. It is very nice for clamping a thin workpiece to the bottom of
the vise while it is worked by the shaper tool. Putting a thin
workpiece on a pair of parallels would risk it bowing and thus having
variable thickness across its width.

Enjoy,
DoN.

Ned, I've got a couple of pairs of those sitting in my toolbox, but I
can't tell you how they work - because I don't recall ever using
them. I know how they are SUPPOSED to work, though.

Flat side down, bevel up. Thin side against the side of the
workpiece, thick side against the vise jaws. Since the thick side is
ground at less than 90 degrees it will bear against the vise jaws only
at its top edge, which will apply downward force as well as the
horizontal force from the vise jaws to the workpiece.

That's the theory. I wouldn't hesitate to use them on the surface
grinder. Shaping or milling generates a lot more force however, and
I'd be reluctant to use them for anything more than light cuts on
those machines. They are called shaper holddowns, though.

Got it. Thanks, and thanks to DoN for his desciption and pics.
