RE PRE-WAR CAR CONNECTING RODS (BN{W.O. Bentley / Mr Barrington}14/W9/3/20)

With reference to the above, Mr. Hives can test the directly drilled hole, but generally speaking, we do not like a hole opposite the maxiumum load.

I should be glad if Mr. Hives would look into any of the aero engine practices, and test any of those he thinks are suitable, and let us have a report.

R.{Sir Henry Royce}
