Not the Same Old Shift
It's time to replace the ugly shifter that I cobbled up after the failed jockey shift episode. My idea was to find an old bicycle and use one of the crank arms as a shifter. After cruising a few yard sales, I found that junk bikes are still to much for the Po' Boy and most don't have the type of crank setup that I'm looking for. So, I grabbed a hunk of rectangular aluminum, put it between centers and cut away everything that doesn't look like a shifter. My lathe has a taper attachment that made it easy to come up with something that doesn't look home brewed. I stopped at the bicycle shop and bought a wedged cotter that most of the older bikes use to hold the crank arm on. I milled a flat on the shifter shaft and the cotter holds everything together nice and snug. At the same time, I moved the pivot up to the same axis as the clutch bell crank. This, of course, necessitated making a new bell crank since the old one had a little 3/8 bushing and the shifter uses 5/8. I cut it out with the torch, cleaned it up on the grinder and disc sander, made up a new hub, popped in a couple of bushings, added a Zerk and it's a done deal. Same for the lug that will weld to the frame. All in all it came out pretty good, I think
