| G.W.Hancock, Esq., Hotel de France, Chateauroux, Indre, France. 23-EX. Shock Damper Elbows. ------------------------- We thoroughly agree with your suggestion of combining elbow and alum cover as one piece. This was suggested when the first scheme of this type was drawn. The D.O. however thought otherwise. Now that you have mentioned it, I am going to have another try to make it practical. Of course in the early stages, when no one knew where the pipes would go, there was more sense in having an elbow, but now it is much easier. These alum. covers are die-cast. The boss might cause a very elaborate die. It seems bad to screw the olive plug straight into alum. With regard to the actual urgency of avoiding leaks, the trouble appears to be only liable with bad initial fitting, in which case it would be found out in the Test Dept. These elbows are fitted by Brock. You will be able to let us know if the elbow holds oil when once it is made a really good job. We hope you are taking note of gland leaks, because some people imagine dampers with high load will in time be more given to oil leaks. With regard to maximum damping, we are rather astonished that you would like even more damping. Does the car hit the buffers flat out on the step between Vatan and Veriezan ? I presume you will run the majority of your time in the max. position to see what you can shake loose or break. We are actually confirming the strength of all the parts on the Bumper Chassis.
