You're working on a Kubota so it's 19mm.

Yeah, but probably on the loader, looks like 0.747 in. to me. They told us all the way through school the metric system was coming. I'm retired now and we're still dealing with it.

I still use them occasionally at work.

Looks like .758" to me.

It’s a NASA Moon-Landing Calculator and Emergency, Last-Ditch Computer. Never needs a battery or a link.

That’s a weird looking hammer.

LMAO. I sold my slide rule years ago to a collector. Still had the original leather belt holster.

I stand corrected.

Edit: Just looked at the pic again. That’s not a slide rule, it’s a vernier caliper.

Have one of those, too but never use it.

Looks very similar to my father’s old slide rule, holster, and manual but his is a white Keuffel & Esser.

Mine was a student grade plastic round version with vinyl cover. Still have that one, too.

 

[RCW]

Don’t think I ever used one?

Was more into forestry, biology and chemistry in high school and college.

Didn't have much exposure, but it was a long time ago…

Passed my caliper on to my nephew when I gave up reloading near obsolete cartridge cases.
38-55, 45-70, 38-40, 44-40, 25-20, 32-20

The slide rule is what got us to the moon!
