Laugh Nearly finished

So I cut the excess off and machined the face off.


What a mess I have taken everything off the outside and created the profile that I am happy with.


Now I am ready to bore the bearing pocket. I have pushed the bearings out of the carrier I am copying so I can measure the bearing pocket I have measured a very slight interference fit of .04 mm to I am going to hit the books to check how much of a fit this is because I have only got one chance to do this and I dont want to mess it up. After I bore the bearing pocket, do a test fitting of the bearings, I have an appointment with the mill and indexing table to make the fingers, drill the bolt holes and remove some material from the sprocket flange so I can fit a stealth sprocket (It has six rivets on it which need some clearance holes/grooves)

You wont be able to see it but I have made this carrier to Fit a yz/wr sprocket which has a larger PCD and a larger inner circle. I have done this so I can swap them between all of our bikes.
