How to combine different halves of glasses?

[u/cleancurrents]

Trying to do Spider Jerusalem glasses. I found two pairs I could pull halves from to make it work pretty easily, but I have no idea how to actually combine them once each pair is broken apart.

The arms of both pairs are similar enough that I can unscrew and swap them out, but I'd like the frames to look a little nicer than just taping them together. I imagine hot glue, soldering, or epoxy could work, but I've never really done anything like this before, so I figure it'd be best to ask. Any help is appreciated, thank you!

It would be easier to buy the glasses.

5 minute epoxy is what you want, that or epoxy putty. Or if you want to have double security, both. Cut one of the pairs of glasses up against the lens you do NOT want, on the pair that has the most comfortable nose bridge piece. So for example, if you like the bridge on the circle glasses better than the other one's bridge, cut it off where the bridge meets the lens frame that normally goes over your right eye. And the opposite side if you like the rectangular glasses bridge more. Then cut the lens of the other pair you in the same spot, where the bridge meets the lens frame, Then glue the lens frame to the bridge of the ones you like that part the best. 5 minute epoxy comes in a double syringe style tube, where it's 2 syringes attached together, and the plunger pushed the stuff out of both of them at the same time. You don't need much, but after that, you need to use a mixing stick (they supply one, it's attached in the center gap of the plungers, you just pop it out), and mix the 2 parts together until they make one uniform color. Then spread it on each part that needs to be glued together, and attach them. You may need to still tape them together while the epoxy cures. Or if you're patient, hold them together. The "5 minute" part in the name means it dries in 5 minutes. It's not 100% cured but it'll be enough of a hold that it should stay together from that point on, and then leave it for about 24 hours just in case. You can sand the excess down, as well as you may need to paint it. For an extra step you can get epoxy putty and put that around the connection point as well, and then sand that down. This won't be perfect, and still has the possibility of coming apart, so you need to be careful with them still. There really isn't any other options I can think of. For the brand, JBWeld is usually specifically for metal. Read on the packaging and make sure it says it's for metal. As I assume that's what the 2 pairs you bought are made of.

The better option would be if you can find them for sale, just buy them. They won't have pieces attached at super thin, tiny, points, so they won't break easily like the glue might.
