More engineering today

Made the central crank web this afternoon, turned up a piece of mild steel to 29.5mm Ø, drilled a 6.0mm Ø tooling hole in the centre, and parted it off to 3.0mm thickness. Placed it in a 3 jaw chuck mounted vertically on the milling machine, and clocked the tooling hole to centre it on the machine. Drilled and reamered 2 holes through 6.0mm Ø in 'Y' +10.0mm position and 'Y'- 10.0mm position.

Then I cut off two pieces of 6.0mm Ø silver steel to 17mm length, and silver soldered them into the central web. I've not cut the 3.1mm wide flats yet, that'll be done the next time I work on it. Check out the pictures...
