Does watching YT scribing make you cringe?

[graham-xrf]

I'm not one to tell someone how to use their stuff. I have several, and enjoy old Dodge trucks. I hate to see people destroy them off road, but I do not have the money to buy the Dodges, and get the folks to go buy a ford, so all I can do is watch. Unless the folks work for me, or are using my tools, there is nothing I can say, but some day they will be sorry, or maybe they are too dumb to know what they are doing, in that case, ignorance is bliss. But, I also think there is a lot worse stuff on YT, then someone scribing with a caliper tip.

This will make most anyone cringe, yet they do not care, they are making insane amounts of money from YT. Destroying a brand new truck is nothing to them.

That amounts to a car porn snuff movie! Yuk!

I think we live in a world where folk can indulge cringe-worthy stuff, making YT videos funded from their subscribers and adverts. They can even do quite expensive lifestyle stuff - like funding the sailboat that just goes from party to party around the Caribbean.
I wonder we benefit from valuable YT videos showing machinist-related stuff. Some are quite the production that would not happen without Patreon funds.

Am I a bit OCD because I try never to put a spanner down across any working parts of a machine, nor throw cutting tools like files together in a box?

I guess the problem I have with this technique is accuracy. Hermaphrodite scribes are adjustable so the leg can set down on the perpendicular ledge from the surface you are scribing. No matter how you hard you try, vernier calipers will scribe a little short of your target because of Pythagorus. For example you would have a hard time scribing a bolt circle diameter on a tube using verniers vs a hermaphrodite.

I’ve tried using the verniers to scribe but don’t like it for that reason first and abuse of a precision measuring tool second.

With that said I have zero problem with anyone else using it. I can see it working for roughing and fabrication layout work when precision isn’t critical and if someone is ok using their tool that way then that is good with me.

Depends on the level of work.

We have a couple no name dial calipers that we use for most everything in tinker and repair mode.

Real easy to do layout work, need to find the center? measure, divide x 2, mark from each end, lines do not match adjust and repeat...

A Sharpie leaves a good spot, light dragging leaves a nice scratch.

Yes, one could get out many more tools to take a lot longer to make the same mark with not that much more accuracy.

Accuracy that is likely not needed most of the time.

At work time is money, at home time is short.

Too many tasks to do in a limited day so one uses the "best" tool for the job being done to get the job done in best time.

Yes, it definitely makes me cringe, and I definitely think less of the folks doing it, it is not a workmanlike way of doing things.

It's not something I would teach , but it's something I do regularly . I'm in charge of keeping production lines running . Most of these lines produce more $$$$ in a single day than I make in an entire year . .

In the past, I have worked "production" lines where my time was measured in "Dollars per Minute". My most recent job was in a steel mill casting slabs at 40"/minute with a produced value on the order of $100/inch. What that boils down to is $4K/ minute. If I could use poor techniques and spoil tools to keep that line going, so be it. There are things I would never consider doing in a home shop that saving a couple of seconds at work was worth more than the tool.

It took 90 minutes minimum to restart the line if it shut down. If I could keep it going by throwing my drawers in the fire, I would do so. A "dial caliper" is a less precise tool than a micrometer. I have several, mostly second rate accuracy that I do use to mark plastics and "Sharpie" marks. I would never show someone as a way to measure, but I do it all the time.

Yes, for a "hobby" shop, it makes me cringe, or worst yet, tune that person out as "professional". But, I do it myself on casual work with "casual" tools. Just like bridging a 240 Volt 100 Amp line with pliers. Never for me, but at work where time matters. . .

I would never consider it. I use a combination square and scribe or surface plate and height gage for that purpose.

And you can quickly set a square with your calipers, if you want that level of precision.

I'm guilty and will continue to be. Yes, it is less accurate than a ht. gage and granite which I have & use when required. A set of Fowler digital calipers doesn't seem any the worse for wear because of it. Crude? No, efficient!

Conscientious. Not OCD.

I quite frequently use my mitutoyo caliper to (carefully) scribe on dykem and similar and couldn't care less.
I have a hard time seeing how a hardened steel would be affected in any way by rubbing off some ink.
Sure, if you go full 240lb gorilla you're of course going to damage the caliper.
But looking at my track record, I break things from dropping them, not by using them in ways they're not meant to be used.

It's really easy to forget that the moving jaw sliding away under the body leaves the perfect depth gauge and edge to be scribed against. Requires two hands, though.

That being said, I'm guilty of scribing in dykem with the pointy bits myself. Doesn't seem to do much harm to the hardened calipers, it's the accuracy that's more of a worry. And really, it's not hard to stone out outside edges to get the points nice and pointy...

I confess I am confused by some of this. Is the correct technique to use a hermaphrodite caliper or a combination square and a scribe? Furthermore, how do you set the prescribed length on said device? I challenge the idea that using the point of a digital caliper would be less accurate than a hermaphrodite caliper. This would make a great video topic.
