Tool Stuff, That I Was NEVER Taught, EVEN After 70 YEARS!!

Yep, but the guy in the store selling them didn't.

How about sometimes you can get a stuck fastener loose by tightening it first?

 

[ruffdog]

If a phillips is boogered up from stripping, sometimes you can flatten the burs with a hammer/punch and then reshape by tapping the correct phillips bit into the head. With all the tapping, they normally loosen easy then.

So, did you know that the coupler on a grease gun is adjustable?

nope I never knew that until a friend told me little over a year ago, but not all are adjustable.

With ALL the anguish I have over tools in general,,

they have JUST came up with a TOTAL solution,,

Researchers look to once-taboo frontier — psychedelics — to treat 'anguished' health workers

Thirty depressed medical professionals will be treated with a dose of synthetic psilocybin — a psychedelic drug — to see if the drug, can reduce their mental anguish.

I did have to look up psilocybin ,, that is a new word,, to me,,,

Anyone want to join me??

I heard it works like,, magic,,,

Interesting post. It is proven once again that history repeats itself.

I loved running a manual lathe (many years ago) and having a tool & die background, I once did some research on how toolmaking all started. I expected it to trace back to blacksmithing. What I found went back into the late 1700s and that the British navy was desperate for nuts and bolts to build ships.

The issue was that each village machine shop made their own version of a nut and bolt, and thread pitch. So their bolt screwed into their nut but probably not the one made by those in the next village. So, not only was there a shortage that made them buy differing bolts and nuts, they had to keep them matched, and also had to try and identify and purchase a matching nut or bolt if one was lost. I don't have the link but it referenced a boy who kept running away from the fields to watch the machinists hand file the nuts and bolts with a vise. He became a master at his craft and eventually developed the first screw machine where the travel of the tool holder was tied to the rotation of the headstock. It was the beginning of standardizing thread pitches. After reading some of this thread, it appears that we have managed to outsmart ourselves back into the 1700s. I have since seen other versions of how the first screw machine was invented and no idea which is true but it does seem that history is repeating.

While I got what you meant, that is one fine typo! Really makes it read funny

I bought one of these when I started working on my Goldwing.

Nails pull easier if you can hit them a time or two to drive them deeper. It breaks loose their grip on the wood.

Stupid auto correct, I fixed it.

Now I've learned two things this month about tools. The first is that 1/2" and 13mm really aren't the same thing. (1/2" is 12.7mm)
I never really thought about it before, the cheap socket sets I got as a kid used them as the same. A couple of weeks ago I attempted to use a 1/2" socket to pull the bar on my Echo and rounded the corners of the nuts... skinning my knuckles in the process.
I then used a 13 mm which spun them right off. The latter fits completely over the tapered nut whereas the first didn't slide on all of the way.

PZ drive works much better and should not be particularly more expensive, a screw design that handles torque so badly as Phillips is pure junk and thankful it's almost dead for all serious use.

The Phillips is wonderful at doing exactly what it was designed to do: Cam out under load. Phillips designed it to be driven with an unclutched power driver, and cam out before it could exert enough torque to snap, or tear out the sheet metal. It does that really well.

A myth to cover a bad design, it was not in the patent application, destroying the screw as a feature is not good.

Just because it wasn't in the patent, doesn't mean it isn't used for that reason. Also just because it isn't perfect doesn't mean it's not useful.

If "it isn't perfect" was a reason to get rid of something,,
my wife would have got rid of me close to a half century ago,,

Phillips have no reason to exist in any new products in 2021.

Ahhh,, yes,, BUT,, 19mm and 3/4" sockets are perfectly identical, (within 0.05") and interchangeable,,
Why they never stamped both sizes on that socket always amazed me,,

 

[ruffdog]

Also, 5/16 and 8mm is very close.

 

[Agvg]

11mm is 7/16, 27mm is 1 1/16, suppose that's why it's used on wheel nuts on old MFs.

Everyone in the world has Phillips screwdrivers. A limited number have other options.
