E/Ev.{Ivan Evernden - coachwork}P/M.24.6.37. WRAITH III, SIDE SPARE WHEEL CARRIER. ------------------------------------- It has been pointed out to us that the bracket/under the side spare wheel on Wraith III. is not normal to the plane of the wheel, since it is at right/angles to the sloping side of the frame side member. The result is that the depression in the bracket to receive the tyre well is not parallel to the axis of the tyre well. This causes difficulty when fitting the wings. To overcome the trouble we propose to increase the width of the depression and to make it consist of two radii and with a small central flat as shown on LeC.5749. This will ensure that the tyre well will always sit on the bracket in the vicinity of the attachment bolts. Att: LeC.5749. E/Ev.{Ivan Evernden - coachwork} | ||
