Ancient equipment...

[EDGEOUTREACH]

Yes, this equipment is well over 50 years old but it produces excellent results. Most optical eq is computerized today but in many countries mechanical tools are affordable and less expensive to operate and repair. The equipment used in this video is now in Serbia. DE at EDGE OUTREACH

Thanks Jake for the demonstrations. Now I know why lenses cost what they

do!

Wow, I remember hearing about the alloy being used for blocking, but that's never heard of.

I agree, the older machines take skill and sometimes take a little more time, but the optics are much better than the automated machines.

I trained (and still use!) on the Coburn 2113, and still prefer it.

Seeing that equipment transported me back to a place in time that I had almost forgotten! Thanks for re kindling some old memories, and yes we had to really know what we were doing back then. We no longer have proper optical education due to computerization.

i trained on equipment like this, a Coburn 108 CT, i miss it, the computerized ones take all the skill out of it. Two step pads give a better finish than one step pads which seem to be the norm now. These older machines are much easier to maintain too and a lot harder to break.

Thanks for posting this video.

Thanks for your comment Frances. Actually the first grinding process isn't done dry. You don't see what's happening inside. Water is required to cool the lens during the grinding process. There are no grit or glass particles in the air. de at EDGE

Bond the grind holding block to the lens by sucking out the air between them using a vacuum? No, by pumping in between what elnoy? To clean it up, you use a what lens microsope at 06:30?

I did not hear much clear.

a pattern edger.

This is nice and the video is informative.

Today we used .only patternless edger
