WAP/LCS. ------------------- Phantom III Front Suspension Lower Triangle Lever Bearing Housing in Pan. ------------------- The housing for the lower triangle lever bearings in the pan consists of a tube on to which are brazed two forgings. It is desired by the Works to avoid the brazing because of the distortion which results, and they suggest welding. We suggest that you try, possibly on the next Wraith chassis, the scheme as shown in the sketch herewith. [Sketch of a tube assembly with an annotation pointing to the joint reading 'Weld'] It is believed that there would be much less stretching necessary after the welding than after brazing but it would be necessary to finish grinding for the bearing after welding.
