Looks good, My HLV is # 461 and thought it would be while before I saw an older one. I was too looking at swapping out to an Inverter, at the minute, I have it rigged so that the ctrl is supplied direct of 240 mains, (bypassing the transformer) and I engage the slow or high run relay’s before I tell the inverter to ramp up. (Not ideal – but ok temporary) I might inquire as to how Cyclematic lathes do their speed control. Do we know how the new Hardinges work ? – be good to see a new Schematic and even more interesting would be the New HLV that has just come out, with the servo leadscrew. In my case I have only just ripped out and restored the wiring to original and everything works fine so I may try to keep it original. Quick question,, with regards to the brake, you are still retaining the mechanical brake solenoid. This is the way I would be doing it, but thinking about it there may be some merit in using the inverter to do the braking, what are your thoughts on that? The auto transformer you are using is single phase, are you doing the same as me and feeding the inverter with 400V single phase ? and not running it at full capacity ? I should really get some pictures of mine on this forum.... I have just got to the primer & paint stage, (lotts of dammage to my carrige gears + rebuilding the carrige feed motor + revising its electronics have taken a lot of time) Best Jon P
