Wheel Question

[Bill O'Brien]

Does anyone know the distance from the center of one lug to the center of the adjacent one???

I measured and got just under 3-1/4".

Did some quick math and got 3.2328". (Using sine or cosine).

Pretty simple to figure. The length of one side of a regular pentagon inscribed in a circle is 0.58778525229 X Diameter. The bolt circle diameter is 5.5000", so multiply. I get 3.2328". Close enough? If you are going to machine something, check my handbook constant and math first. Easier to index 60 degrees, if you have the equipment.
