re: #98 Teukka

I actually own a slide rule, basically the prepper in me which says I need to have a calculation device not dependent on electronics. I’m on the lookout for a nice abacus too.

I’ve been wanting one of those giant classroom types teachers used to instruct whole classes in the use of the slide rule. Turns out there are a fair number of them around. Apparently out of pure inertia, many school districts ended up storing them long enough for the potential collector value to be realized. “Slide Rule Instruction Guide, Photos And Information Etc.”

Pickett manufactured large slide rules for mounting in the class room. They came in 4 foot and 7 foot versions. The stock and slide are of plywood (tongue and grooved), the end brackets are sheet aluminum. The cursor consisted of pine with aluminum paint, with a clear plastic lens. Both sizes came with metal eye loops for hanging from a wall or ceiling.

I am not sure I remember how to use a slide rule.
If I had a 7 footer in my den, I could probably re-learn pretty fast though.
