I don't know that a front lift/stand is better than your method. I assume you can do it your way by yourself. I guess your way is just as stable as a lift/stand. Maybe your wood rots faster than my stand will rust??
Hope you take this as intended, just lighthearted, not criticizing your method.
I'm such a newb on this stuff I just liked what I saw on other front stands and wanted to see if I could duplicate the effect for less $ than buying one and w/o the cutting and welding needed to do one like someone else did recently in stainless steel. I got $60 worth of entertainment from planning and building the lift I did and in using it down the line.
But, tell me about the extra boards under the center stand. Are they necessary in order to pull the rear wheel? Is that also a fender issue? on the center stand and front stand I've got about 1" of clearance at the rear between tire and floor. Will that be enough to pull the wheel?
