With reference to the use of Rudge-Whitworth wire wheels for front steering wheels, we find from careful tests and experiments that it is of very great importance that these wheels should be approximately in balance. We notice that it is your practice to arrange your spokes in "14 series or bundles" which necessitates the security bolts being arranged unequally, i.e. the security bolts divide the spoking up into 4 series of 3 bundles and 1 of 2 bundles of spokes. This system of course puts the security bolts out of balance. In addition to this point (which is of course of comparatively small importance) we notice that the tyre valve is placed adjacent to that part of the wheel which | ||
