I don't get how everybody kills hole saws so fast? Take your time and keep spraying it with WD-40 or something similar (I used something called Power Lube), and they'll last a long time. I knew an old timer that used to stuff a wet paper towel inside the hole saw, that works great also. Once they get too hot, the teeth go away. It does take more time with the hole saw, it probably took a little over 2 hours to drill 4 holes.
I've had good luck with the Kobalt hole saws available at Lowes. I started with a fresh one, but it went right back into the tool box when I was done.
Chris, that jig looks like a good idea. The sleeve on my drivers side didn't come out perfect, it's not bad, but not perfect. I think that was because I didn't get perfectly centered on the hole. That's why I said if the template just gave center instead of the outside diameter, it would work better for the hole saw user. I think I just didn't get the true center when I drilled my pilot hole.
