More on the Crankshaft

A day off work, and as the weather forecast is better tomorrow, I'm in the machine shop today.

Finished the front crankshaft part, see pix below:-

I've made a start... To give you an idea of the scale, the 3 jaw chuck is 80mm dia.

A 6mm dia. pin is used to aid setting.

Nearly finished, just the 3.1mm dia. clearance hole and M3 thread to be cut.

Finished and assembled to the centre web with an M3 grub screw.

The hole is clearance size down to the centre and threaded into the 6.0mm hole where the centre web assembly is clamped with an M3 grub screw. Sorry the photo is a bit out of focus, I wanted to get as close as possible to show greater detail.

Flying tomorrow - with a bit of luck!
