I have now sorted out the centre boss and extended one side as they are a little short.
I have now completed the main turning on these, with only the tapered turning on one side of each to do, and the holes drilled for the fixing flange to attach.
I also managed to form the keyway on both, which I was nervous about as the broach is only 1/8" wide, but it went a lot easier than I expected.
