| (2) to be set-up as the smaller angles must be done by hand without opposition from spring, so that comparing the effect with that felt when using a very reversible worm we definitely do not want set-up, and a simple (clock type) spring around the worm shaft (hand wheel shaft) in a spiral or helical form is all that is wanted, say three strengths, about the same as generated by the axle pivot inclination which can be calculated. The effect should be more manifest because it will not have to pass through the irreversibility of the nut. I would like to point out to Mr. Day that he is asking for too great a variety of parts, resulting in being unnecessarily expensive, and the result is we may not get anywhere. I suggest we reduce the requisition to the most hopeful and simplest things that promise to shew us which way to go. I believe the above covers all the ground as we know it. The new PhantomCodename for PHANTOM I axle has done much good, and we want a 20HP. of the same physical proportions - i.e. out of centre steering, etc. This will shew Mr. Day and Mr. Bailey what to do with recent drawing on the above.
