tape it, then a metal cutting chop saw, (don't push hard). flush well and blow out. good luck.

I used a dremell with a thin abrasive disc. You can make 2 to 3 cuts before the disc is used up. It cut it very cleanly. Tried the hacksaw but it was way to much effort.

Thanks for the suggestions guys! I bought an air powered Cut-Off tool. It works pretty good. Plus, I can use it for other jobs too.
