After a couple hours more nice warm sleep I decided to make some use of the day and finish up the swingarm pivot plates. The shop was deserted and quiet, nice conditions to make some progress.
I had left the parts setup in the mill so that realignment for the bearing bore operations would be easy. I can use the same boring bars used for the engine bearings.
Bore out one bearing hole...
With all the fixtures and programs done and verified, making a second part only took a couple of hours:
The parts look great and I'm one step closer to getting Scott down for some sheet forming and welding sessions.
Next up is the upper shock mount crossbar, a much simpler part that should go quickly.
Free t-shirt to first person that spots something that's amiss in the pictures. Post it in the comments and google will be the time-stamp arbiter.
UPDATE: here's the problem that can be seen with a close examination of the second to last picture:
I'll have Scott Kolb weld this mistake up and then remachine the bore to size. Normally there would be a concern about the welded material in a stressed area losing its temper and strength but this part will be heat treated after the entire swingarm is welded so it will then regain its full T6 temper strength.
