[Boatanchors] Final chapter: Help on drilling out knob setscrew

[LeeCraner at aol.com]

Thanks for all those who responded with suggestions on drilling out a 
stubborn setscrew in an aluminum knob.

A few of you suggested diamond drills/burrs from Harbor Freight, which is the 
route I chose, since there wasn't a hole left in the setscrew for an easyout 
or a left handed drill bit.

The set of diamond burrs cost about $4.00 from Harbor Freight.  As you can 
imagine, the quality of the burrs were terrible at this cost and the diamond 
coating quickly wore off.  However, with a lot of bit changing, I was successful 
in grinding away the remaining portion of the setscrew while saving the knob 
(albeit now with a larger setscrew hole).  

Without this reflector's help, I wouldn't have thought of the diamond burrs!  
Thank you again.
