Yamaha R6 7075 alloy rear axle and oil cooler bolt

I’ve just finished a 7075 alloy Yamaha R6 rear axle, nut and oil cooler bolt. I like 7075, it machines nicely but it is a bit messy. The oil cooler bolt is different to the R1, its about the same everywhere else apart from the oil gallery area under the head.

The nut is made as one piece, the original arrangement is a nut and washer, but a flanged nut is much tastier! 32mm A/F and 38 on the flange.

Couple of photo’s of the finished items to follow.

        Thank you Dean, it is a wonderful thing to work with your passion, the problem is knowing when to stop! Man give me a break, i’ve only just bought a smart phone! the most technical thing about the one i had before was it had a torch on it! So live streaming is a thing for the distant future, apart from anything else i don’t have the screen presence for such a thing!
