Introduction: New Finish Eye Glasses Frames

Picture of New Finish Eye Glasses Frames

So your eye glasses suck and you want knew ones cause the frames are all messed up, but they want 200 bucks for the designer, blah blah blah.

Or you could remove all the rubber, sand down the frames with 220 grit sand paper, go to your local techshop and powder coat them into a new shine.

And so that's what I did for my friend. I would have preferred a nice neon pink, but he wanted black... boring.

It's all about the prep.

Remove anything that will not survive 15 mins at 400 degrees F.  All rubber, plastic, etc.
Then sand (by hand) the existing color off until you are down to the metal.  Frames can bend so sand blasting is not recommended (or they can slip out of your hand and fall down into the blasting cabinet).

Line the inside of the frames with some time of heat resistant tape, or regular tape but you will have to pull it off before putting the lenses into the oven.  This is to protect the pockets that hold the lenses in place.

Unscrew the joints and separate the frames. The goal here is to avoid locking up the hinges. Next get some simple green (wear gloves) and degrease the metal to remove your finger prints and residue.   Then hang the frames from hooks and pre-heat them for 5 mins at 385 degrees to cook off anything problematic.

Pull them out, let them cool down for 5 mins and then spray away with the color of your choice.

Bake'em in the oven for 15 mins at 400 and WALA, the process is complete.

Enjoy your new frames.

Lastly,  If you have trouble popping the lenses back into place or inserting the screws, just take a small screwdriver and scrape away powder in the hard to reach places.

That's it, Bob's your uncle.

Nice job! I found your Instructable while looking for things that other people have done at TechShop. I refinished my glasses frames at TechShop too (Detroit). I sandblasted mine, but I covered all the screw hole areas with masking tape to prevent enlarging those holes, and I also covered the insides of the lens areas on the frame so I didn't enlarge the grooves that the lenses sat in. I had no issues with pieces bending, or with dropping them into the bottom of the sandblaster. When they were blasted clean of old finish color, I cleaned them with acetone before powdercoating them. I taped off the screw holes and the lens grooves with heat-proof powdercoating tape so the holes and grooves didn't get plugged or change size because of the paint.

The finish turned out great, and over a year later they still look brand new. I took them back to the optometrist right after I painted them to have the lenses put back in, and to have new plastic ear pieces and nose pieces put on them (the old plastic parts were pretty much worn out). The folks at the optometrist's place were very impressed with how they turned out. I've included pics I took just now. Sorry if the pics are a bit blurry, I can't see to photograph my glasses with my glasses off. :) But the powdercoat paint I used is a very subtle rainbow color-changing holographic glitter over black. It really only shows up under bright lights or outside in the sun. When I finally get new frames again I may just powdercoat them immediately and save myself the trouble of going through watching the original finish peel off.
