Belt drive and pulley sizes

[8iggles]

I've just had the first run out of mine - 10t 5mm pitch 16mm wide on the X axis and same but 10mm wide on Y axis....I have just got them running through pieces of rubber air hose as a temp direct drive.
For the Z I have used an old G cramp for the acme screw and a sprung 2nd nut to take the backlash up...I'm trying to keep the cost down and so far its working quite well (well nothing beat me so far)
The 10t pulleys are small but it seems to be working ok and next I'm going to reduce by about 4:1 (fingers crossed for fathers day) - I managed to tap out 8mm for 8mm shaft and carry on using the skate bearing theme :)
I have just done a video on youtube if anyone is interested www.youtube.com/user/8iggles#p/a/u/0/FTQ2c-HvNvI Dont expect too much theres still loads to do I just pushed myself to get a run and prove I'm on the right track!
