ShopTalk: cleaning out epoxy in a graphite shaft

[Ralph Harwood]

I have a problem that maybe someone has an idea for me.  I removed a 
graphite shaft and am planning to use it on another head. I normally 
clean out all epoxy from inside the shaft with a very small drill bit. 
The drill bit I used is a very small one and is about 2 inches long.  My 
problem is that there is epoxy still in the shaft that my drill bit 
cannot reach.  I still have about an inch of epoxy to remove.  My 
question is whether there are small drill bits available that are at 
least 3 inches long and still effectively work without breaking? Or is 
there another solution I just have not thought of?

Thanks!
Ralph
