TOM: Perfect redlines & whitewalls

TIP OF THE MONTH: Perfect redlines & whitewalls

OUR TIP OF THE MONTH IS Gary McCulloch’s second tire-related submittal. This “Tire Painting Machine” was conceived after Gary painted his own thin redline tires.

Granted, it’s quite a bit more high-tech than what we usually feature, but it’s a great solution to a perplexing problem. If you don’t have access to a lathe, with a little imagination you can modify the concept and create a similar tool to suit your needs.

The idea is to center the tire on a shaft and paint a perfect circle on the tire by placing an outer sleeve (with paint on its bottom edge) over the shaft, then press the sleeve against the tire’s sidewall.

Gary machined the center shaft so it had a tapered bottom to automatically center different size tires. The center was drilled to accommodate a bolt that screws into a threaded hole in the base. If you’re making this machine for only one size tire, you can permanently attach the center shaft to the base and get the same results.

The critical part is having the outer sleeve fit tighyly over the shaft. The width of the whitewall (or redline) depends on the wall thickness of the outer sleeve.

He machined each end of the outer sleeve differently so one end can be used for whitewalls, and the other, thinner end for redlines or thinner whitewalls.
