CNC v-groove routing for PC board scoring?

Hi Folks,

I'm looking at having some cirtuit boards made but I want to save money
and do the v-groove scoring myself. For those not familiar with the
process, a v-groove is cut in the top and bottom of a circuit board so
there is a small web left in the middle. Once the board has been
populated a wheel-type cutter breaks the board along the score lines
and separtes the sub-boards from the main board.

The real machine that does this uses a saw blade-type cutter that has v-
shaped carbide tips on each tooth. This would require a horizontal mill
(which I don't have) so I bought a carbide v-router bit from a
woodworking store.

I'm basically wondering if anyone else has tried this or could point me
to a discussion or a website that talks about this technique.

Thanks,

Jeff
