I ended up using the press to get the eyes closer together as much as the gage would allow. Then pressed a bit more without the gage because of the spring back. Then used the vise to bend the arms to get the eyes parallel and repeated the whole process. Also used a pipe over an old spindle to remove a bit of twist. I had a bar of 6061 T6 which was turned down to a slip fit in the eyes. It was used for the final ( hopefully) alignment and now fits though both eyes with nothing more than a turning motion.
The arbor press in the background of photo 1 wasn’t used if anyone is wondering. The feeler gage in photo 3 is .008”. To get rid of the .008” it would mean bending the arms again, which in turn would mean I would have to realign the eyes so that they are parallel again. I think I’ll call it good for now and just live with the shame of putting a .004” shim behind each eccentric. As my avatar would suggest I’ve stocked up on shims since returning to the Vincent fold. Ever wonder if the motorcycles were just a front for their shim factory?
I laid it out on V blocks and it gets the green light. I still have to confirm dimension F is equal side to side or at least within normal shimming distance, whatever that might be.
