I regret to say there is no real progress other than a drawing and some good intentions.
My excuse is that the pilot motor, (needed to create a psudo 415v 3ph supply for my ancient milling machine), died some time ago and replacing it has proved something of a problem.
This is one of those “for want of a nail…” stories, this being the expurgated version. I have a truckload of other excuses to go with the motor one but I suspect you already have a life!
For the same reason there is also no progress on my ’49 Shipley ‘box-o-bits’ if that is any comfort.
