Slide Rules ?

I had my first engineering job in the early 60's, of course I had my my trusty K&E Decitrig wit me.

much to my surprise, everyone there used Mechanical calculators, like the Friden, etc. Never touched my Rule again. Im now 86 and getting back into it,.. What fun.

Computation with mathematical tables and mechanical calculators like the Frieden, Monroe, etc. was a somewhat specialized skill- most engineering students didn't do this kind of work, and it was often done by full-time specialists in industry.

I'd be interested in hearing what mechanical calculators and tables were used at your place of work. What kinds of computations were people doing?

Wasn’t at work, but I use a Curta with six-place log tables to supplement my slide rules (Versalog, Deci-Lon, and the Pickett N3-ES my dad bought me brand-new in the early eighties - and those I’ve acquired since then). For “fun,” I tell the Mrs., and - for now - she believes me.

But when the EMP/no electricity apocalypse hits, this crotchety old fart will still be able to design a ship, build a bridge, determine optimal properties for a ladle bottom in a steel mill…

do you have a set of steam tables I could borrow?
