Great use for the slide rule!
I was a freshamn when they took the teaching slide rules (5 -6 ft long) off
the walls in college;
I so wanted to buy one of them!

So THAT is what a slide rule is for!?!?!? And all those years ago I thought
I was supposed to use it in my engineering classes! Silly me!

Hi,
So like my 8x10 2-D camera with a 360mm
lens has big bellows sag, and for a long time
I couldn't figure a simple solution. Then I
tried a slide rule: just right! It adjusts for length
and the clear plastic gives extra support that moves,
plus it anchors on the front and back wooden shelves
of the camera.
I think I learned how to add and subtract with it but
that's about it. Maybe a portrait prop today.
