Hi all I have read on the list, some time ago, about machining the armature of an induction motor to make it synchronous. I have read descriptions of what to do but I am still unsure of what is actually required. Are there any images that I could look at to get my mind straight on the procedure? I have been off list for a while due to house move and work and apologise if this has been covered recently Dr B, Church Crookham, England
