CHASSIS BATTERY SUPPORT WITH UNIVERSAL SUBFRAME. Replying to By6/G3.6.30, in order to take full advantage of the universal type subframe it is necessary to have a cantilever support for the rear end of the battery. Since however, the type of body, namely 18-EX, which requires this modification is a comparatively small part of our output, and in any case we are no worse off than we are now, we think that we might, as you suggest, revert to the cross member support in order to avoid waiting for the 10,000 miles test. The effect of the cross tube is to interfere with cushions on bodies of the 18-EX type, but for normal bodies the difficulty does not arise. With reference to your remarks about the attachment to the battery we do not agree that the middle portion is of no value as the battery box is controlled from the rear end, and this part is necessary in order to stiffen the rear edge. We suggest that in place of the plain angle we should use a pressing as indicated on the enclosed sketch. (N.Sch.3121). We have not yet received a print of N.Sch.3114. (26-EX must have the cantilever). Da.{Bernard Day - Chassis Design} | ||
