Had my first follow-up with surgeon today (he's pleased, so I'm pleased), but before I headed to Winchester I finished up a pair of TAV Jackshaft Brackets to install on Copperhead, my "mule" bike. The difference between these brackets is the TAV bearing mount is welded to rather than bolted to the main body of the bracket. Additionally, I used a 1" OD x 3/4" ID sintered bushing for the swing arm rather than the impossible to find oblong bushing. Materials include 3/16" plate stock and 2-1/4" rectangular tubing split in half.
I pre-drilled all the bearing/bushing centers and bolt holes with the matched pairs clamped together. The rough shape was cut with a sawzall (I cut four at a time which I will not do again), then finished with an angle grinder. A Greenlee 1-3/8" carbide tipped hole saw did jackshaft bearing holes and step drills were used for the swing arm (I will get a Greenlee 1" hole saw, if I do this again).
