Sandvik coromant carbide way scraper
 

I have a couple of Sandvik Coromant way scrapers, they look like this:

http://yabe.chudov.com/Sandvik-Corom...raper-0578.jpg

The stuff under the red plastic tip is a big carbide insert.

I am trying to decide if I should keep one or sell both. Are they only
useful for high end precision way scraping (which is something that I
probably will never do)? Or do they have some more mundane uses?

One mundane use would be to mount the ends securely to a block of wood and
keep it on the verandah. It'd do a fine job of cleaning the dog crap from my
boots after a walk in the park.

If you you drop something on your machine way or table, this is a good tool
to scrape off the raised ding it made.

You might find precision scraping is fun. It is one of those mindless
concentration tasks similar to meditation, only instead of just staring at
your navel, you end up with a beautiful flat surface. If your kids like
making stuff, it might even be something they could do on a small scale.

I've been reading a series on scraping in one of the home shop
magazines. Apparently if you start playing with that, you'll probably
be making a lot of your own scrapers. Doubt I'll do that, to many
projects, not enough time.

On the other hand, I've rarely seen anybody get as much accomplished
as you, so who knows? Besides, remember that first lathe and sweet
Clausing mill you sold? Bet you wish you hadn't at least once, would
have made good tools for your boys some day. Plus those don't take up
much room, just keep them in your personal tools.

Pete, thanks a lot for the compliment. I am, actually, happy that I
sold my busted Clausing lathe and replaced it with a much better
clausing, glad that I sold two mills and got the Interact, also.

I will probably keep one of these Sandvik scrapers./

Iggy, I've only met two people who actually knew how to scrape the ways
on a machine. Both were OLD, and both made their own tools from HSS
blanks.

Although I'm sure the carbide will last longer between replacements than
a hand-honed edge, these guys both "tuned" their tools about every ten
minutes. I think the attention to the "instantaneous" condition of the
edge made a big difference in how their work turned out.

My question with a carbide scraper would be, "How do you tell when it's
not quite keen enough to do the quality job I want?" And then, of
course, how fast can I get new inserts?

I learned rather quickly that indexable inserts get dull, too! G

HSS dulls so quickly even on soft cast iron, that it is a major pain.
Carbide stays sharp enough for 15 - 30 minutes.

I made inserts for an Anderson Bros. handle from pieces of scrap steel
brazed to 3/4 x 1.5" x 1/8" carbide blanks that I got on sale for a
couple $ each. They work VERY well, and are easy to sharpen on a
diamond wheel.

I scraped in a Michael Morgan straightedge, then did a set of 3 right
angle plates. My Sheldon Lathe was too hard to scrape, had to
spot-grind that using the same techniques of spotting but used a die
grinder for the removal of material.

Ah, if you're like me, you'll know right away. I can barely push the darned
thing when it gets dull.

All but one of mine are made out of old files. The one that isn't is a
Nicholson, which looks exactly like one of their files with no teeth, but
with a flared tip. That one has a thigh brace for pushing it.

Yeah, that's probably the "old guy" vs. the "new guy" thing. They did pay
a LOT of attention to their edges. One guy used a stone, but the other one
had a nice diamond lap. Both checked their edges for a blackout on a small
surface plate.

Sounds reasonable! I've never attempted a scraping job myself. I probably
will in a while, when I completely re-build the old R2E4... if for nothing
else, just to check how it is.

It's worth trying it, if only to see why you're glad you don't do it for a
living. d8-)

Back in the '70s, I spent parts of several visits to Moore Special Tool Co.
watching their scrapers flattening jig grinder and jig borer tables to +/-
20 millionths, corner-to-corner. Moore guaranteed 50 millionths, but the
scrapers had too much pride to stop there.

They were interesting people. One was an attractive woman about 25 years of
age.

I've only dabbled at it. Scraping, that is, not attractive women... d8-)

Lloyd, I can guarantee 100% that I will never scrape any machine ways
that are worn, as a restoration project. I will keep this scraper for
some minor jobs, like repairing dings.

Heresy! You've removed the seasoning!

Actually, it's easy to restore the seasoning - I bake some peanut oil
onto all surfaces.

Couple quick swipes across the bottom face of any gasketed surface will
restore the bike's original ability to leave puddles of oil on the floor.

Yeah, the iron-pan purists would drum me out of the corps. But I do what you

Ive got to stick a set of Triumph stickers on a computer case and take a

Funny you should mention - it really did happen.

Back in the 1960s or so, Univac 9400s had a hydraulically actuated disk
drive. When it worked, it worked well. But not for long. I never knew
the reason, but these drives were famous for breaking and spraying oil
everywhere. Puddles were normal. These drives didn't last long in the
market.
http://www.iceinspace.com.au/forum/archive/index.php/t-69978.html

IBM had (and probably invented) hydraulically actuated disk drives, but
I don't recall that they tended to spray oil.
