Kevin is the mei edger master at pech optical!
I found it curious to see a post from you. Just use your fingernail until it develops a nice groove to clean the lens. That could happen in an hour at Pech.
For those of you who don't know, Kevin knows more about bevels, finishing wrap eyewear and the MEI edger than anybody else in the world. He started working on a machine that was designed for plano ski goggles and now designs his own tools, bevels and then designs the entire cut process on a CNC machine that happens to cut lenses.
The software was designed for an engineer to program each plano job and then run 10,000 lenses of the exact same size and shape. It took the combination of no less than 3 programs to get a job to run. KEvin now has the one high volume machine running 60 jobs per hour- not lenses, but pairs. He also supervises the other 3 custom machines that can produce the custom wrap work that Pech specializes in because of Kevin.
I was at Pech over 2 years ago when the first MEI edger was still in the testing phase, now they run 4 of them on 2 shifts. I was just back a few months ago and was amazed at what Kevin has done in the past year alone. He has designed fixtures to keep the large 8 base lenses from tipping when the blade hit the lens and flexed. No one had ever used lenses that big in 8 base poly and Kevin designed and built a fixture to secure the back of the lenses and prevent lens flexing. They call it Iowa engineering.
When Oakley programs a new SKU into the MEI edger. it takes 2 engineers 4 plus hours and they start out with the CAD drawing from the original plano to work with.
Pech has Kevin!
Thanks for being who you are and being committed to always putting out better work and continuing to improve.
See you in Vegas!

Poly Edge Polish................
Kevin.............Polycarbonate Edge Polish will act like acetone used to work on Cell frames. It dissolves the surface and makes it glossy. No need for buffing.Originally Posted by Kevin W

Touch lenses off on a DRY handstone with very light pressure. Always worked for me.
I use a razor blade, all my poly come out clean-shaven!

Kevin,
Hilco has a new tool called the "Swarf Removal Tool".
It is product# 20/317/0000 $21.99
www.hilco.com
I have not used it. I use an old metal PD stick or a razor blade.
Good luck and thanks for all of your hard work and dedication to our business!

2 things to try...
When pin beveling a poly lens make sure the lens as well as the wheel is perectly dry.
Secondly, this is the one most people get wrong...
press VERY VERY lightly on the lens while turning. pressing harder will only 'burn' the swarf into the lens and make it harder to remove.
pinbevel 2x, start with a flat beveling, and again at a 45 degree angle.
Peels right off, good luck.
I also use a piece of carpet! I take the lens and run it over the carpet at an angle! Works every time and is really effective on the stubborn swarf!
No offense meant, Kevin, but for the few MEI wrap jobs done at PECH so far, the edging *quality* is not in the same class as Oakley, IMHO.
I'm available if you want to discuss my experience.

Point taken...I'm sorry I made my opinion in a public forum.

Finger nail and some cold water or a priest if one happens to be available.
Flat bladed screwdrivers work good too.
I always use the polish setting on the edger so there is very little swarf left to remove. I use my fingernail to remove any left but there is usually very little.
It only costs $21.99 and 2 ruined lenses before you will decide to throw it in the trash.
I use the swatch of carpet trick (commercial grade closed loop). It works well and I learned it from Optiboard! No scratched lenses and no metal objects near my lenses. Maybe I'm not as coordinated as you guys that use razor blades.
I use a piece of plastic strapping that is wrapped around the opti-free cases. Cut it at an angle and it works like a charm...

I worked in a lab once where they used this small brush with plastic bristles. I don't know what they're normally used for, but it worked great for getting out the swarf in grooved lenses, and didn't mess up the lenses or coatings.
I like Craig and Fezz's suggestions. I have always been a big fan of my right thumb nail. Works great. Then when I start bleeding, I go to a soft cotton lint-free towel on top of a hard surface and slowly, but forcefully rotate the lens on the towel.
