Here's a couple of Rube Goldberg contraptions that I cobbled together early on for edge bevels.
they borrow ideas from a bunch of different sources (including some sharpenig systems) I thought they might help someone though, so here they are

For a filing jig, I came up with this




For hollow grinds, I modded it a bit
and came up with this one. You can change the radius of the grind (making it shallower or deeper) by changing the angle you hold the grinder.



hope this helps someone

Very helpful!  Thanks!
