Please receive herewith the following scheme :- F.CD.1107 Temporary scheme for Mounting Front Jacks. The above scheme shews Wraith lll permanent jacks fitted to Wraith 80. We have shewn alternative methods of producing a mounting bracket, but think you will prefer the B. scheme, which shews a fabricated bracket comprising a tube with the flanged ends butt welded on, and the angle brackets spot or tack welded to the tube, whichever is the most convenient. We believe this type of mounting bracket may be cheaper, and as efficient as an aluminium die bracket, and would like your comments on this type of bracket for permanent use.
