So more engineering. I've made a start on the crank shaft front part. All the diameters are turned and the M6.0 hole has been tapped. Its now ready for parting off. I'll do that with a hacksaw, and although this sounds a bit crude its my preference in this case as the part protrudes out of the chuck by a long way. Parting in the conventional way would be a bit risky.
Notice the DTI on the cross slide to assist with accuracy.
Turning the 10.0mm dia. Revolving centre for support and helps prevent chatter.
Ready for parting. Note the M6.0 thread has been cut.
Oh! yes, and I've cut the flats on the central web as seen in the log below.
