So I had a sheared off steel bottle bolt, so no head to work with. I bought some easy outs and set about drilling the pilot hole. Once done, I started with the easy out, but the alloy rivnut sheared off inside the frame (the threaded part only). Hmm, bugger as the easy out was also stuck. I had to cut the easy out down to allow me to remove the remnants of the rivnut from the frame. A pain but no big deal.
So what do I do with the rest? With no thread, what's left of the rivnut serves no purpose, but it's a carbon frame so I'm assuming it's bonded in.
What are my options?
I don't plan on using a bottle cage, so perhaps some form of blanking plug? Normally that would be the job of the bottle boss bolt, but with no thread to screw it into, I need another plan to stop the crud getting in, and a plan that allows me to do the same with the other bottle bosses with threads still intact.
Can the rivnut be replaced? As mentioned, frame is carbon so I don't want to do any damage.
Any help or ideas gratefully received.
