Mark used his Lathe to modify these ATV Spacers to make a wheel size adjustment.
This customer was changing his wide 4 wheeler tires to narrow tires. He had spacers to make the narrow tires the same width as the wide tires. The spacers locate on to the centering ring of the hub. But the inside of the hole of the spacers was to narrow. So Mark bored the backside of all of the spacers to the correct size so then they could fit on the centering ring of the hub perfectly.
