Bump. I melted the Loctite today and when the set screws backed out, I developed a gas leak. I'm kicking myself for not knowing to do it differently, but it's too late for that.
Anyways, I was wondering if I can use my FSB with the set screws for installing taper pins. The real estate where the taper pins normally go in my FSB is empty, so I don't think there would be an issue drilling through my FSB for taper pins. Does anyone know?
I wish I could just buy a new upper, but I can't justify it when I can eventually fix what I have.
