I used a die grinder with a cut off wheel to rough them in and then finished the teeth up with a file. I made up a small template to lay the tooth pattern out.looks pretty good.
what tool did you use to cut the teeth?
I have had to file some in the past.
I'm planning to do that, too. You could always get someone to tap a little weld on the short teeth and grind them back to size...I ground 3 extra teeth on each end of the rack.
