hey

i got me a hudy advanced with bearings and a diamond bit

i also took the time to set it up perfectly and made sure the arm holders were perfectly square to the slides. i also shimined the bit with calapers to get it just right

as a result i can make very fine cuts

the motor i have been using has been cut regulary by mod drivers who should know how to use a lath but, when i got my own and cut my motor correctly the performance jumped from when other people had cut it.

i would go the diamond bit, you will be suprised how many cuts you will end up making. i cut my stock motor every 2 meetings (club, 5 racers each meet so 10 runs to a cut)
