SpectreCodename for Phantom III Marles Type Steering. We visited the Adamant Engineering Co., Luton, yesterday and they raised the question of the cages for the roller bearings of the rockershaft and of the roller follower on the rockershaft. Apparently we have asked them if they could supply the above cages to our drawings Nos. F.87131, 87143 in brass. They object to the use of brass for these cages as they say that according to their experience they will not stand up to the job. They suggest that they should make them in steel and of a design similar to the ones they already supply for the roller bearings of the cam. We would prefer this ourselves, as their design of cage has the advantage of retaining the rollers during assembly. Will you please send them particulars of the roller bearings in question to enable them to make sure that they can get their cage into the space available and to design the cages.
