Burrell Traction Engine - Milling machine power feed.
Some years ago my father designed and made a power feed for the Centec 2A milling machine,
this used a small geared sail winch style 12volt motor. It engages with a dog clutch and can drive forward and backward's one direction by a gear drive, slow speed for milling and chain drive in reverse a lower gear so high return speed. My father being a mechanical engineer was unable to use it in anger and so never connected it up to a supply. I remember he tried to make a speed controller using a Triac circuit out of a Maplins book but it was not finished.
Since I had spare a bench power supply with variable voltage and current 0-30 volts, 0 - 3Aamps I decided to connect it up and after some oil, I was milling with my hands in my pockets.
Door Latch
The door latch required 2 pieces of mild steel milled to the correct thickness and as I had a nice piece
of slightly oversize MS, I used the power feed to quickly machine it down to size.
Pleased with the results, just need a polish with emery to remove the machining marks
