| - 2 - DA.{Bernard Day - Chassis Design}12/G.6.9.38. (6). Exhaust Pipe Joint - Wraith. Already dealt with on E.CD.689. (7). Axle Driving Flange - Wraith. We suggest that the bolt holes should be used for withdrawal, and that HPS.{Horace Percy Smith - Experimental Factory Mgr} should test whether any distortion results. The elimination of the thread would save costs. A scheme has been done by BY/CRL.{C. R. Lisson} Should this fail, we can increase the diameter of the internal thread. (No withdrawing tackle has yet been made). (8). Starting Handle Bracket - Wraith and P.lll. We can tap .025 deeper, and suggest details should be altered. As these washers are only used when no fog lamp is fitted (Rare, we believe), another suggestion would be to leave the set screws and washers off altogether when this happens. (9). Fan Pulley. P.lll. Agree to detail being altered to eliminate lightening holes. (10). Clutch - Phan.lll. Details already altered. (11). Connecting Rod Bearings. P.lll. Details already altered. (12). Brake Pull Rods. Ph.lll. Our instruction to do this has been issued Da.{Bernard Day - Chassis Design}18/G.{Mr Griffiths - Chief Accountant / Mr Gnapp} 21.4.38. (13). Brake Actuating Levers - Bentley. All the bolts for 'M' and 'N' series are produced, and so we think this question does not arise. DA.{Bernard Day - Chassis Design} | ||
