Huh??

McCray Optical in Toronto, Ontario has the rights to all of Chris Ryser's formulae. Drill Seal is exactly the same product as Chris' Instant Poly Edge Polisher.

1.60

You always have interesting takes and comments, too.

I have my own line of nut-and-bolt rimless frames, and I use it all the time on those. For Silhouette and other compression fittings, though, trivex is the best.

You should be able to get 1.60. While Trivex is by far my preferred material, I'll use MR-8 1.60 or MR-10 167 with success, when necessary. You just have to much more careful when putting...

Safilo springs are the best I've used. Lightec has decent ones. Otherwise, frames with flexible metals or plastics are better than frames with mechanical springs.

Some make the frame more durable, but a lot of the designs are the Achilles heel of the frame

For example, +3.00 sph. PALs in poly on a 4 base?

The frame was an old Totally Rimless 134.

I made a pair of compression mount rimless with a -14 once. It worked out because the bridge was quite wide, about 25mm, and the lens shape was a small oval. I had to do some notching on that one...

You're hilarious!

Cherry Optical, Inc. in Green Bay, WI is the best wholesale lab I've used during my thirty-plus year career.

If I were trying to make lenses for that frame, I would use Trivex (which may not be available or widely used in the Czech Republic). I would take it down until just slightly large and then take...

Love it!! Bravo!!

Yes, it seems that aviator shapes are popular with the glass-loving folks.

A few years ago, I acquired about 60,000 finished glass lenses. While most of them aren't the sort of size necessary for today's large frames (50-55 mm blanks), many are still usable. There are all...

Too bad. The frames I've sold that were distributed by them were pretty good quality.

I use direct water -- no recirculating -- so going from material to material shouldn't be a problem. I actually already own an edger that could be used only or mostly for glass, but there are two...

I'm considering buying a new edger. One of the edgers I'm considering can be fit with a glass roughing wheel. The questions are, how much demand for glass is there presently, and is the demand...

Vertex distance and the distance to the heart of the reading area, taking into account vertex distance, corridor length, and panto might also be something to consider. The greater that distance, the...

I ordered and received some Trivex round segs just recently from my favorite lab, Cherry Optical of Green Bay, WI.

That's something which has been happening with mine for years on certain jobs. It's a minor problem which can be fixed with a hand wheel. If it happens often, don't let the machine safety bevel...
