MAIN BEARINGS FOR TRIPLE

Each main bearing consists of 2 gunmetal halves which fit into a slot in the base, and a cap which bolts to the base.  There are 6 of these.

I machined the gunmetal castings, and made the caps.

Before I finished the machining or drilled the holes for the bolts, my phase changer failed, so I finished the job on my (single phase) drill press. Not ideal but adequate.

The Phase Changer has failed at least once every year since I bought it 5-6 years ago.  It is the least reliable machine in my workshop.  Repairs to it seem to take at least 3-4 weeks on each occasion, which is frustrating.  I will borrow a 3 phase diesel generator to keep the workshop in action while waiting (again) for the repairs.
