| COPY. G. {Mr Griffiths - Chief Accountant / Mr Gnapp} Dept. c. RHC. {R. H. Coverley - Production Engineer} c. HPS. {Horace Percy Smith - Experimental Factory Mgr} BY {R.W. Bailey - Chief Engineer} /NS. {Norman Scott} 8/G.24.8.38. WRAITH. CHANGE GEAR MECHANISM. GW.1794 SHAFT - GEAR LEVER. This piece is at present produced in S/ZN.2072 and has the 1.200 diameter sphere and .3995 wide lugs hardened. Will you produce a drawing shewing the shaft produced from S/N. 2063 with a brinell figure of 302 - 320. The note referring to the hardening will not now be necessary. The drawing should be issued to the Experimental. They should then have a sample made and tested. If satisfactory it can be introduced on to production. The object of this change is to enable the O.P. Department to produce the change gear shaft with fewer operations. BY {R.W. Bailey - Chief Engineer} /NS. {Norman Scott} | ||
