Nice work there but I'm not understanding what the shaft cut at 45 is for?

The cut at 45 Deg., allows the short piece to slide when the bolt at the end is tightened and locks to the spindle ID holding the whole assembly in place. Simple and effective.

Yes, that's exactly it, quick and easy solution !
Thanks

I'm just a regular looker. Lots of great ideas.
Thanks, Dave

This is the same mechanism used to position the handlebars on a bicycle - at least on the ones I had as a kid.

I was wondering the same thing and guessed it must be to wedge the shaft in the arbor hole maybe?

When the 2 pieces cut at 45 degrees are drawn together they expand inside the spindle and jam.

Works equally well for square stock; handy for something that needs to lock into a square-sided slot.

To lock it into the spindle bore like the gooseneck in a bicycle :-)
