Instrument Glass Repair Kit

Works very well but be prepared to spend time to get good results. My glass came off without breaking the flange on the old housing. Took a rotary tool and ground down the flange on the housing. Had to tapper this area to fit the new lens. Next had to lap the housing down on a flat surface using a sheet of sandpaper. I found a flat washer to use as a 2mm gauge for proper height. Instructions say to apply glue to lens, but I applied glue to housing. Before gluing I practiced placing lens on housing as there is only one chance to place correctly. End results were perfect. Instructions do not tell which side on the lens gets glued. The black ring on the lens is the glue side. My explanation may make more sense after reading instructions. Protect the lens. It does scratch rather easily.

These make so much sense in replacing the old glass and glass frames. When you get them, and after reading the directions, you will see how they all fit together. One thing, be very careful with the Locktite. Be as accurate as you kind of only have one shot at this. I got the locktite on the lens then tried to clean it off with goof off (didnt work), simple green (no way in hell), then acetate, and boy, did the acetate do a number to them. Ate through the first protective layer on the lens and permanently clouded it up. But other than that, these are right on if you can install them right! Good luck!
