Chris,

Note that most drill rod is NOT hardened: the intent is that the user  
harden then temper the rod after forming into the desired tool or  
whatever.  Spring pins are usually hardened, and trying to drive it  
out with a soft steel rod may bring a bent tool.

You may want to just find a drill the right size and use the non- 
drilling end of it.  Start short to get the pin moving.

If I were trying this, I would be careful to not bang on any bearings  
the shaft may have: I'd arrange a metal standoff with hole in the  
center to support the pinned collar, or some other such thing.
