With reference to the trouble you are having with rubbers of varying consistency on production. Will you please arrange that the test for their deflection should be altered to one-tenth of an inch deflection for 250 lbs. load plus or minus .005". Rubbers that are Mr within these limits should be assembled selectively if necessary to give equal balance on the engine feet as we do not think we can expect the manufacturers to make them more consistent than this. hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson} | ||
