Plastic Weld Sunglasses
I have a pair of sunglasses that I particularly like, and I have managed to keep from scratching the lenses for about 5 years. However, I did manage to break the frame and one of the lenses kept falling out. I really like these glasses, for the lens color enables me to see the green in my plants which helps me to better schedule their watering needs. Being in the desert, I try to conserve water, and the summer watering is mainly just to keep the plants alive.
I have tried epoxy and super glue, but the glasses just kept breaking at the same place, and of course the lens kept falling out. I decided to try the new plastic welding tool kit for the next repair. After reading more about the different plastics in the enclosed manual, I was ready to give it a go. I clamped my work as best I could, and per instructions, I cleaned the old glue off and made a rough surface for the new plastic to stick.
Once my soldering iron was hot, I began my welding using the proper plastic rod, supplied in the kit. I added plastic, and smoothed the weld a number of times by using the iron to cut the plastic from the rod. I then melted it into the sunglass area. After going over the repair process a number of times, I was satisfied that the weld was sufficient to supply a proper hold. I told myself that it was time to quit the repair.
