Cycle Repairing and Adjusting
With a Chapter on building a Bicycle from a Set of Parts

48 CYCLE REPAIRING or wired edges will require very well cleaning and solution- ing to get a good, firm support at these places. When repairing such a place as this, the cover should be removed from the wheel and turned inside out during the operation. The repair of the outside or tread will best be done on or off the wheel, according to the nature of the damage. If it is a clean cut or tear without any of the tread being loose from the fabric, it may be done best with the tyre on the rim and partly inflated. But if it is a very bad place and partly come away from the fabric, it may best be repaired off the rim, as the tread must be lifted up to get underneath to clean the surfaces well before solutioning. After repairing and the tyre is on the rim, it is well to partly inflate, bind some tape round the repaired place tightly, and then fully inflate, leaving the tape on until the solution is quite dry and the machine is required for use. The longer it is left before using; the more chance of a permanent repair is the result. Loose Places in Tread of Cover.—It will sometimes happen that the tread will get loose, or come away from the fabric without any other damage occurring. I his, if neglected, will result in the grit and dirt from the road getting in through a cut, and forming a large, unsightly lump in the cover. The best way to treat this is to cut a place in the rubber large enough to work the grit and dirt out, and thoroughly to clean the two surfaces with a piece of rag soaked in petrol on a piece of stick ; but do not begin cleaning until every particle of dirt is worked out. Then a good coat of solution should be worked in through the cut made with a small brush. The two solutioned surfaces
