    Bottle Opener made at Techshop

    Nice! I made the same basic bottle opener in the metal shop SBU at TechShop Detroit. I "cheated" and powder coated mine when it was finished, though. :)

    Sandblasting Rusty Cast Iron cookware

    I did this with some old cast iron "hobo pie makers", aka camping pie irons, that we bought at a thrift shop. They were rusted inside and out. I took them to TechShop and sandblasted them, then my husband re-seasoned them with lard on our outdoor propane grill. He added another brushed layer of melted lard every 30 minutes or so for about 5 hours. Those pie irons are slicker than Teflon now, nothing sticks to them, not even eggs! I'm not concerned about "rendering them worthless", I wanted them usable again.

    New Finish Eye Glasses Frames

    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...see more »Nice job!

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.
