Harrison L5 lathe rebuild

Hi Steve, I had mentioned about the rev counter in one of the posts above with a link to a unit on E bay which also has a wiring diagrame too. Mine acctually displays on its own display the round digital clock lit up with blue didgits on the right hand of the switch panel.
I am not sure if you could make it display on your inverter display but if not the Ebay link is to a smaller square unit that would be easy to mount, even maybe on top of your inverter ? I think some inverters can show RPM but this will be motor RPM not the spindle if its thecinverter sensing itself. Maybe some will allow you to add just the sensor and takecthe in put then display on the inverter display ? You would need to checknyourcown inverter manual I think.
Hope this helps Mick
