Step 3Calculate the leg locations
I used three legs but in hindsight four would have been better. Three legs is a little tippy when the stool is high and a person is getting on or off of it.
Starting where the opening for the inner tube valve stem is, count the spokes on the rim you plan on being the seat. Mine was 36. I divided that by 3 and used that number to space each of the crutches out 12 spokes. Note that since each leg has two attachment points that the spacing will be from one leg "Y" to the corresponding "y" of the next leg. Mark the locations of the six attachment points with the marker.
