This is just like the one I used as an apprentice and now own.

You still own one? That is at least a 50 dollar memory!
Sell it to Mike, or use it as an job-interview test.
"Buyer pays shipping"???????
Those things are HEAVY!
makes excellent ballast for anything up to 24 feet
Just think how much less work it would create with the cribbing pliers.
That is what I learned on too! Does that mean I'm an antique??
Had a couple of those in my basement. I felt guilty throwing them away...but if Mike says he doesn't even use them, then I did the right thing. whew!
LOL -- but remember these were used to crib a lens down before edging, back in the day before diamond wheels, when all there was to use was ceramic wheels.
Nice. My dad used to have one in the back of his optical shop (yes, opticians did their own in-office "edging" even back then!). It etched or scribed the lens shape onto the glass blank from a pattern, and you sized it using the large wheel with gradations (you can see 50 and 55 in one of the pics). You used a cribbing tool to "crack" away the excess glass around the etching (glass was much thinner then, before the gov't mandated thickness and tempering). Then it was on to the ceramic hand stone to bevel it before glazing into either a rimless, plastic, or plastic/metal combination frame.
I think we still used this, very briefly and only occasionally though, when I started working for him. I vaguely remember breaking a few while cribbing as it required a certain touch to do it without breaking the glass, or chipping it excessively, inside the scribe. But I also remember that there were automatic edgers (huge in size) in use as well in the laboratories.
