On shafts that have a smaller mid section than splined end, like my Johnson, what is the best way to shorten the shaft? Welding? Pinning? Squaring and adding a coupler? Something else?
Dave
We have cut one end square, and the other five sided, then we get a socket wrench that fits the square, and the five sided on the other. Like a half inch SNAP ON socket...
Socket size depends on the shaft sizes, of course.
I'm an "IDEA" man.....Thanks, Brian, for correcting me....six sides , five sides....There is a difference, but we don't use the 12 point socket, only the six, seems stronger.

Bill Curtis uses a craftsman deep socket and cuts the square end off Makes both ends six sided

Great. Thanks. Sorry but that leads me to another question. Since the thin section of the shaft is .500" and the larger sections are .625" would I want to cut at the lower transition (arrow in pic) and make the four sided end on the .500" and the six sided end on the .625"? With a six sided deep socket I guess I would have to stick to the .500" section just above the lower transition? I know Craftsman also makes 1/2 in drive sockets for 1/2 in (and larger) square nuts. . .
I will be shortening the shaft approx. 5 inches. Thanks again for the info. Dave
