If you have one fixed flange, I think the other would just tilt as needed. Usally theres a fixed 'step' in the grinder shaft that one flange rests apon.
bench grinder is definately on my project list too.. so many ideas..
So far my favorate is making a 5C 1"~ collet holder to a reverseable bench grinder motor (3600rpm~) and then making arbors for my wheels, precision made on my lathe and clamped perminately to the wheel so that I don't need to true them after swaping wheels or try and replace them 20 times to get everything aligned. Basicly a quick change grinding/wirebrush/polishing wheel system. And maybe some kinda reasonabley quick wheel guard removal and table style change...
Probley have 2 of these setups, one for traditional radial grinding wheels, and another for face/cup/cone grinding wheels like toolroom grinders use.
I wish I had some kinda information about what bearings to use to hold the grinder shaft...
PS: I think iv figured out why most plastic bushings are 'loose', its because when you clamp the wheel from the side, it will shift the alignment of the wheel, if the bushing was tight, it would snap the wheel. I think the solution is buy proper 1 peice bushing as the multi peice ones I don't think are gonna hold accurately enough. also don't reuse em, they seem to have ridges along the side to allow deformation of the plastic when the wheel shifts on clamping, so they get deformed/worn on the first use. Alternately, or maybe even better, make your own custom perfict customised to bench grinder shaft bushing that goes to say, 1", then use the 1" to 1 1/4" plastic bushing only (and machine to fit its interiour perfictly)
