Using Loctite 660 to repair a stripped splined shaft

For repairing tubular or cylindrical mating surfaces, like the door handle or the window crank on this old Ford COE truck, Loctite 660 is a fantastic solution. I had several options for fixing these stripped shafts and handles, such as pinning them or cutting keyways. But I was able to avoid that complexity with some Loctite 660.

Loctite 660 isn't an adhesive, like the epoxy the prior owner tried to use to fix this...and which failed. It's some kind of magical compound with (what looks like) metal suspended in a hardening base. When cured, it fills gaps and prevents the poorly mating splines from shifting relative to each other...locking the handle and the shaft together.

Easy peasy, lemon squeezy!
