We have to thank you very much for the time both you and your assistants gave the writer on Friday afternoon last when we had the pleasure of discussing the latest position regarding Aluminium-tin bearings. It is understood that the AC.6. material, according to Mr. Wheeler, is not satisfactory, from a casting point of view, and that by going over to AC.9, which eliminates the Antimony content, it will be much easier for castings and that the results as regards uniformity of material throughout the whole of the castings will be much better. We have therefore written to High Duty Alloys briefly mentioning the position and requesting that they should let us have the AC.9. material as soon as they possibly can. Regarding the position of using Aluminium-tin bearings on soft shafts, you mentioned that from your own point of view you would not run any more bearing tests as you are satisfied regarding big end bearings and that main bearings are satisfactory in Babbit material. You suggested, however, that as we were keen on making as wide an application of this bearing as possible, that it would be advisable for you to make a test with bearings on a soft shaft, and that this would involve some expenditure. This was briefly mentioned to Mr. Howlett over the week-end, who agrees that this should be done, and we suggest therefore, that you should let us know at the earliest possible moment as to the course or test to be | ||
