Default disolved my pocket knife

I lost my regular pocket knife I've had a knife in my pocket for 50
years now, feel naked without it. There was an old swiss army knife in
the everything drawer. None of the blades would open unless you
grabbed them with a needle nose vise grip. So, I opened everything
half way and tossed the knife in dilute phosphoric acid and left it
overnight.

this morning it was more than loose. All the blades were floppy and
the retaining springs had come out. Don't soak your knife in acid.

I did a major cleaning and soaked some neglected tools in ATF. Loosened
them all up nicely.

I buy small pieces of aluminum from a shop in NC. Its substantially cheaper
than buying stock locally even after freight, and they are already precut to
the length I want. Anyway, I opened a box of aluminum rod the other day and
found an old beat up wooden handle knife in there. The kind I used to call
an electricians knife when I was a kid. One regular round tip blade and one
locking blade with an end squared off to make common screwdriver. I asked
them if somebody was missing their baby. They told me to keep the knife and
thanks for the business. So Karl. Were you over at Stock Car Steel a
couple weeks ago? LOL.

I've received strange extra presents in McMaster-Carr deliveries, as
if they were disappearing stuff that doesn't sell.

Once upon a long while ago, I bought one of the little 4x6 horizontal
band saws from MSC.

Within two weeks, all the smoke escaped from the motor. So I called, and
the next day on UPS came my box.

It was kind of heavy... inside were THREE motors!

Hmmm... called 'em back and explained. The guy was really nice, and
said, "They're not worth shipping back. Just keep the other two; you'll
need them!"

That was over 15 years ago. I still am working on the second of those
three -- third is still in the box! G

Non-UL, non-thermally protected, rated at twice what they'll actually put
out, aluminum windings.... typical Chinese crap.

But the third motor I installed has been running for over 12 years.

I worked on a car like that. "Fleet" vehicle, engine made way to
much noise, but it ran. My boss, John finally got desperate, and had
it issued to Niles. Great guy Niles, but not the best at ... err,
monitoring vehicles. We expected the car to get towed in with a dead
engine. It never did. Finally, John had it brought in for "a regular
check up" and pulled the engine anyway.
VW engines are not suppose to go 150 000 km without trouble.

I carry an old-timer #340T--no other knife will do..

And since the newer "made in China" "old timers" are totally out of the

Occasionally, they do pop up on Ebay as NOS and at antique stores though,
and so these days I actually have a couple of spares stashed in my

Don't set your electronic calipers onto a ketone soaked rag, either.

The black molded plastic reader-head is oddly misshaped, but fortunately,
the lcd window is still (mostly) clear.

Sad to hear that. I can imagine what it's like to misplace a pocket knife.
Hope it returns soon.

I had a cheapie Swiss, years ago, much the same problem. Someone suggested
pack the end with polishing compound, and repeatedly open the blades. Might
have worked. Being decades older now, I'd reach for some spray oil. Or buy
another knife.

My daily use knife is a Stanley SM -18 that I got from Home Depot, three
bucks. In the tool crib along the wall with screw drviers, and crescent
wrenches. I've resharpened it many times. The pocket clip is perfect for
shirt pocket carry.

That's what I do. I have some pocket knives that date back to the
1930s, and I have polished them that way when they get a little stiff.

I dissolve some Deco stainless polish in paint thinner, pour it into
the joints, and work it until it's as loose as I want it. It works
very well.

It took me years to find a Camilus electrican's knife in good
condition. I bought my first one when I was 10 and carried one for over
35 years. I probably bought a dozen of them over that time. The spares
would disappear out of my toolbox when I turned my back.

I finally landed a few at a reasonable price on Ebay last year.

Phosphoric acid/Naval Jelly will really do a number on high carbon
steels. I had some brake hardware I needed derusted and did the same
as you. Most of it was a nice smooth gray the next morning but the
springs were heavily pitted and one was eaten in two. Needless to
say, a brake hardware package was obtained from NAPA. Didn't do that
one again. Keep the rust-removers away from the high carbon steels.
It's like the phosphoric acid goes after the carbide grains
selectively.

I fell for you- really.

I made an attachment - a lathe tool holder attachment for my Aloris AXA
post. It was out of a block of Iron. The Iron would rust lightly
once milled. So overnight and it pitted it and etched the whole block.
The dovetail cut I put in was sloppy so I put in a spacer to compensate.
Taught me to do in little tries.

I used to buy it by the gallon. Moved away and lost the source.

I would dip shovels into a tank and then put them in backing soda barrel
to help clear it after washing it off. The gray metal was good for a
coat of paint or as it was.

Wes fired this volley in
:

And that was "a" third of the four that MSC originally provided,
including the first one that came on the saw, the next one from the three
they gifted me for a single replacement, and the second from that same
batch. I still have the last of the three replacements in a box, waiting
to do another 12-year stint.

The saw cost $199.00

Hmmm... not bad. 12 years, $199... That is $16.58 per year, for a saw
I've used no less often than five times a week, every week, since I've
owned it.

So... say 250 uses a year... or just a touch over 6-2/3 cents per cutting
session (MANY of which are 10-minute cuts).

That's what "a" motor that works right can do!
