Yeah, Jamie, the grinding has it's place for sure. It's a lot messier and a lot noisier to do a lot of grinding. Since I do this work all at home and I live in a fairly dense residential neighborhood, I can do a lot more drilling w/o too much disturbance.

One way to keep the bits sharp is to keep cup of water handy and dip the bit in the water after each hole. I have done maybe 400 holes and broken 3 bits. I have a Drill Doctor, too. Everyong should have one of those. It's paid for itself twice over since I've had it for about a year.

Finally, I think I agree about the spot weld bit. I have never used one, but they are pricey and don't look like you can sharpen them easily. So. I just drill as deep as need be to break the weld. Many times I go through. I will weld from the backside where possible anyway, so the holes are good for that.

(BTW, Jamie, your money is on it's way. Thanks again.)
