Fun with the Plastic Welder: Sunglass Repair

Grant (now 2.5 years old) LOVES sunglasses, but he’s always breaking them. I have some Sugru lying around, but I just purchased a plastic welder off of Amazon to fix a hole in my hard-shell kayak. I’m still waiting on the exact HDPE  (high density polyethylene) from the kayak company to repair my boat, but Grant provided a pair of broken glasses to practice on today.

I taped the glasses together to keep tension and did my best to work some of the melted plastic onto the break. You jam the plastic onto the tip of the welder to get it melty/bubbly, but how you get it off the tip and into a seam is a bit tricky. The weld isn’t the prettiest thing on earth, but it looks like it’ll hold and it kept Grant entertained for half an hour while we fixed them. I went over it with a dremel sanding wheel after to smooth out some of the rough edges.
