now this is something that is of great interest to me.. i've not taken the top of my x3 apart yet to see whats in there, but if i'm getting it all right, you made up a couple adapters, and swapped the toothed pullies? hmmm very interesting.. i use very small carbide cutters, the largest of which is 1/8, and go down to 1/32.. and i know that due to spindle speed limitations, my cutting feed rates are really slow..

i would like to know more, see some pictures or something like that.. i would also like to know more about this belt drive that your talking about, did that totally eliminate the gear noise in the head? whats that all about.. cause i would be worried about turning thoes gears that fast for too long.. the bearings are already getting pretty warm, and i would think that a good portion of that is due to gears in the head creatiing some of the heat...
