Sorry for the late reply Wayne, been waiting for some kind of comeback from Mark but looks like his age is catching up and his responses are slowing.
Not got much done, ripped out the HiAk drives, removed the computer box and looked at a few things. Have made up an arm to hold the control screen/panel, it now swings from the top of the headstock and can be hauled round to the chuck or pushed out the way against the headstock. Also took the endplates off the motors and they are like new inside, not even the slightest trace of carbon, just shiny copper and brass
Will hopefully be oredering some drives, encoders etc soon, I have settled on the Teknix drives, hope yours are still living up to expectations.
