| X3806 BY.{R.W. Bailey - Chief Engineer} from Hs{Lord Ernest Hives - Chair}/Gy. Hs{Lord Ernest Hives - Chair}/Gy2/LG20.2.29. With reference to BY2/G19.2.29. We are entirely in agreement with your remarks. As regards (B). We think we ought to design a drip plug entirely and instruct accordingly. We are continually having the brass retaining caps dislodged by the pressure of the Enots gun on the axle, even with air reservoirs, while we have also had several fall out on the foot operated system. This is a very serious matter but we believe it can be accommodated by allowing more metal for peaning over. We should also instruct that the .052" hole be reamed in position. The design of the steel shell in regard to the banjo, we understand you are proceeding with now. If possible we think it would be possible to make the cap solid instead of two components as this is an insurance against errors in manufacture. Hs{Lord Ernest Hives - Chair}/F.Gaye. | ||
