VISIT TO BURMAN & SONS LTD. 750 June 26th, 1941. re "Myth" Steering Box. I am sending a print of this as result of our conversation DB.{Donald Bastow - Suspensions} This visit was to settle the final details of the steering column and box. They are now preparing their final drawings and will send these on to us in the course of a few days. Among the details discussed and settled were:- Approximately 3 turns lock to lock - They will take their nearest standard lead for the worm to give this figure. Filler plug to be in the column above the box, approx. 6" above the box top end. This will make the filler more accessible. Black finish all over. ( The steering wheel hub is covered with black moulded material). We accept their stationary tube fixing coil seal at the bottom of the box; they are catering for a 15/32" (.469") dia. stationary tube. Their oil seal consists of a conical felt washer trapped between two cones and so compressed on to the tube; the tube is clamped by a clamping bolt in a split boss. They were rather worried that the box might move inside its clamp, and after some discussion it was agreed that they shall fit a lug on the box at the top end, and we can extend the aluminium bracket upwards at this point to match up with this lug probably with an adjusting washer between the two lugs. Any movement of the mounting spigot of the box and resultant bending of the column has the effect of tightening up the worm shaft. They said that they could make the pendulum lever, in their normal material which has a 70 tons/in2 ultimate, and this was agreed to. They would require the part for machining the splines fitting on the rocker shaft in any case. Normal delivery quoted was two months, but this could be shortened if necessary. They would like a print of our steering arrangement (PL.448) to check up on loads, etc.. If this is thought inadvisable, I can send them lever lengths etc.. instead.
