I finally made time Saturday to finish up some windshield/handlebar mounts for a buddies Harley. I made the bore and squared up some stock a couple weeks ago. Now I just had to turn the radius and complete them.
Started by making a mandrel to mount the blocks on my rotary table.
Boring to fit over the morse taper/mandrel.
Test fit before removing from lathe.
Now test fit into the rotary table.
Set up on the rotary table.
Dialing in on center. That little modified NOGA test indicator holder sure comes in handy.
Plunging away around the radius.
I made a climb milling finishing cut.
I then flattened off the ends where the fastener will be.
One down, one to go.
Setting up the second one on the rotary table.
Ready for the next step of removing the center portion.
Center portion removed and deburred.
I didn't have any .625" stainless steel rod so I had to improvise and use some stainless steel bolts.
Getting closer.
Set up in the collet block to drill the .380" hole through the head.
Completed and ready to be picked up by the owner.
All in all a pretty straightforward and fun little job.
Mike.
