Any stand I make will probably be quick and dirty. :-]
I tried to describe a height using the belly button to try and have a common measurement for differently built people.
I am interested in the possibility of sitting down. Do you rest your forearms on your thighs for stability? An adjustable chair could make up for different size wheels etc. and be easier to change than a table. One negative I could see is putting your crotch in a more vulnerable position if something should break or get snagged.
Thanks, Tim
