| X328 ? Exptl. Dept. Hs{Lord Ernest Hives - Chair}/Les.26/JH. 29th April, 1936. Messrs. Silentbloc Ltd., Victoria Gardens, Ladbroke Road, Notting Hill Gate, LONDON. W.11. For the attention of Mr. Harris. Dear Sirs, Thank you for your letters of the 27th inst, and of the 28th inst., with a lot of useful information. We have been looking into the question of the unit G.84361 and find that your last consignment of units were quite satisfactory. We are arranging for our drawing to be altered as follows :- (1) Diameter 3.039 to have a limit of +- 2. (2) That the centre of the inner sleeve must not be greater than .005 from the centre of the outer sleeve. This means a possible variation of thickness of the section of .010". With these limits it appears to us that it will be unnecessary for the outside diameter to be machined after assembly. Will you please let me know your views. We are busy drawing crowds of "Floatex" units for body mounting. Can you let us have a drawing of the P.R. and S type units having rubber mounting. The attached prints G.81746 and G.84362 show the details of the neighbouring parts to G.84361. Yours faithfully, FOR ROLLS-ROYCE LTD. | ||
