J.{Mr Johnson W.M.} F.{Mr Friese} FRAME - TUBULAR CROSS MEMBER. This one, with flanges forged solid on the tube, looks extremely good and light, and if makeable, should be very much less costly. I should attempt to produce this all square as a straight tube, and when it is finished set the ends to the required angle in a special rig, with or without heat, but making rather a short bend at the point where the cone joins the parallel.
