Cont'd.{John DeLooze - Company Secretary} planing to the required thickness of the steel (which must not exceed about 050) and the bearing surface the resulting strip is rolled round a knurl to the required radius and finished as usual. They are giving us drawings of the tools for the last processes and are making one complete set of trays Bentley size, which are the same as Pontiac. They will also give us drawings of the plant and full details. Obviously flanged bearings are very difficult tho' Allison have made a few. G.M. point out that only one bearing in the engine need have a flange and this could be a separate piece. This material runs successfully in Pontiac engines in which ordinary lead bronze will not work. Oil temperatures sometimes reach 320°F.{Mr Friese} on Pontiac engines.
