[TheForge] followup on holes in saw blade

[Andy Gladish]

A couple weeks ago I was having trouble drilling holes in some knife blanks 
made from surplus metal-cutting bandsaw blades.
What I ended up doing was heating to critical in the gas forge, then 
blocking the door, turning it off, and letting it cool slowly.
Now I can drill them, though I wish the drill didn't chatter and squeal so 
much...
Thanks for the help, everybody!
