Hi All
Thank you very much for the kind comments, out of my other 2 engines, the Potty Mill engine and the Monitor it is the sweetest runner.
The flywheel was made from a billet. I doubted my ability to end up with a true running wheel by following the MEM design.
The billet was mounted on a faceplate with mounting screws positioned where the spoke cut outs would be. The rim was turned and a recess machined. The bore was drilled and then finshed to size with a boring tool. The wheel was then flipped on the faceplate and a short axle put in the bore and held in the lathe spidle with a collet, this provided location only as the wheel was again bolted to the faceplate. The second recess was machined.
The disc then went onto my BCA which you might know has a built in rotary table. A while back a contributor (and sorry I have forgotten the name) published a comprehensive step by step guide to producing a spoked flywheel which I have found excellent. Even so each time I twiddled a wheel I did a sanity check to make sure I had moved the right distance in the right direction, towards the end it became a bit nerve racking.
