Cheers Rod i do like that cam idea on that eq platform, though a direct drive would give me much better results. I have looked at DC box's as well though see speed is an issue for direct drive units as it more RPH not RPM. I have being on the yahoo group as well, lol downloaded every file they have and have gone mad on the web grabbing/reading anything i can.
I might give that guys drive a go as its a first build and later track down a direct drive unit. Another drive which i liked was the tape drive but that one you found could work out sweet like a barn door tracker cheers
