Dish of Wheels
Improperly or insufficiently seasoned timber all through will cause a general shrinkage of the wheel after the tire is on, which means that the wheel will lose its dish. A wheel with the spokes driven without dodging is more likely to change its dish than one with the spokes dodged. The greatest influence exerted on the wheel after it is contracted and tired is by the rim. Its shrinking or swelling will re-duce or increase the dish just as often as such changes occur with the rim, as it takes up or throws off the humidity or moisture of the atmosphere. Use a thoroughly seasoned rim. Try and have the spokes of each wheel of equal caliber and weight, and as soon as the rims are finished, give them two or more coats (tread also) of metallic paint (good white lead is the best—never mind the new-fangled fillers with fancy names—and while you will not wholly overcome the trouble, you will reduce it to the lowest possible minimum.—BOT.
