I'm a bit disappointed with the radius on the right hand end.  My rotary table has 12mm T-slots but the base is too narrow, so the ones for my mill won't fit.  I used some bolts and cobbled something together that I thought would work, only to have it slip and put a flat spot on there.  Tried to blend it with a file but didn't want to take off too much.  It is now happily deburring in the tumbler.

Other than that I'm happy.  I've told the owner that I strongly advise they take it to an engineer to have it inspected before heading down the back straight, as I don't want to be responsible for him becoming a greasy spot on the armco barrier  

Before I signed up to join this is one post that really caught my attention.

It's exactly what Im wanting to make for a couple of my own bike's. 

Would you have any hint's and tip's Mayhem please before I start on some block's of alloy? Having looked at some of the commercially available CNC'd adapter bracket's Id say your's look a lot chunkier and stronger than some Ive seen!

Do you know what grade of alloy you used. It's easier to type alloy rather than aluminum or the correct British way of aluminium. 

Incidentally Im wanting to buy and fit 2007/2008 Yamaha R1 6 pot radial's to fit to my Yam FJR1300 and some other radial caliper's to my Suzuki Bandit (turbo). As a bit of a sideline note to this, did you know it's cheaper for me to buy s/h brakes from the US auction site than what it is from the UK one. What a crazy old World!
