[TheForge] followup on holes in saw blade

[Jerry Frost]

Masonry bits are carbide not diamond. Of course if you do use diamond bits 
be sure to keep it lubricated and cooled or just throw the money out and 
save the headaches.

I think I mentioned this early in the thread but I've had very good luck 
annealing hard high C steel for drilling by chucking up a piece of round 
steel rod about the same dia as I want to drill, then with it turning I 
press it into the part where the hole's to go. Once the part turns red I 
retract the rod, let it cool and drill.

It's fast and saves a LOT of forge fuel.
