| TEBS/L20612. June 20th. 1912. Re Worm Axle. On February 4th you suggested that we should try a worm wheel of bronze having 10 % of lead in its composition, but in later sheets however you recommended that we should not proceed to make any further parts and confine our investigations to what we have already made. In your sheet dated June 15th you state however that you would like this tried. Mr Nadin unordered the castings to these specifications on the 20th June. X 141 | ||
