TM51.
The machining will be a mixture of manual and CNC. Most but not all roughing will be done manually. Finishing of the sections where the G-code can be written manually and those sections which lend themselves to using some G-code generation software that I have written will be done with CNC, the rest manually. I have no intention of spending the time to make CAD drawings in order to do 3D profiling of the undulating surfaces. Those sections will be redesigned to have fewer flat levels. The critical bearing bores will be made with a nice Narex boring head which I picked up a couple of years back.

here are a few pix. of progress to date as per your request. The original case halves weigh 4.1 and 4.2 kg. One of the new ones still weighs 8.5 kg and the other 10.5 kg so I still have a lot of swarf to make. I spent all morning machining and was most disappointed to have only removed another 1.2 kg.

RHS cases from inside and outside. This is the most complex half case.

Inside of LHS case. Simpler than the RHS.
