LEC.1845 - STARTER ACTUATING DEVICE. --------------------------------------- This seems quite right except that I cannot quite understand how and where the solenoid casing in the casting becomes tight, and how the coil inside it is held still - (the single locking plate hardly sufficient). First we might make a slow taper press fit once for good and always. [Diagram of a cross-section of a component] Caulked here. The coil with its wire ends is pushed in, and clamping plate same as your locking plate, but with longer tail. Or could the coil flange have lugs thus - (3 preferred with spring washers). [Diagram of a circular plate with three lugs] Iron. This latter convenient in every way I think. R.{Sir Henry Royce} | ||
