To avoid too much bonking with Mr Silky :facepalm2: I let H rough out the crankshaft, taking 19mm off above the journal and 9.5mm down the sides.

It is looking a little closer to the shape of the Seal crankshaft  :thinking:

Anyone interested in the discussion of CNC turning of crankshafts  I have moved the posts to here: http://www.modelenginemaker.com/index.php/topic,9269.msg206127.html#new so that you can discuss it without hiding it in my Seal thread  ;)
