Nice advice.
I dream of building my own stand too, the ones I have seen available locally are not to inspiring, they look fine for a wheel/chain service but perhaps not for hanging off your wrench..
I must admit that our bikes are fairly simple for reliability and daily errands, and mostly have Shimano parts.
My next job then is to take photos and references and go to the LBS to see what they have.
I see that a pair of sets of dedicated narrow fixed spanners / wrenches for pedals and axles would be useful too. Would that be the “cone wrenches”?
