I need to chase the threads on my aluminum 22mm hex heads from my Sunday frame. I marred them slightly when a pair of pliers slipped. The damage is slight, and I think if I chase the threads I'll be fine to continue running them.

A) Can I effectively chase them by simply installing them into the (assumedly) harder linkage, gently? Will I risk damage to the link?

B) Where can I find someplace to borrow a thread chaser for friggin 5 seconds? Will a good LBS have one?

The diameter is 22mm, so it's pretty big, but I want to do this right before I mess anything else up.

try calling your LBS to see if they even have a chaser that size

most shops wont loan tools out (dont blame them) unless you are friendly with the guys there
bigger national auto parts stores rent tools as does home depot

or buy a new bolt

I'd be happy to kick them a fiver to chase the threads...it's a lot cheaper than buying new ones...which are available from only one place...in britain....for 25$ a pop....but I'd rather not buy $122 worth of tools for a quick chase.

Picture of the part?

5er won't do it. They will charge you whatever they have to in order to make that $100 tap profitable. So $100/4. That sounds like a pretty funny size though. Bike designers have a habit of putting a 1mm pitch on anything, no matter what diameter it is. Going that far off standard makes it pretty hard to find the right tap.
