Armstrong steering is just fine thank you Scotty.
Got almost what I wanted but enough to proceed with the repair. The original felt oil seal will now have a proper new type oil seal to stop the leaks. Unfortunately no new bearing cups or cages to suit. So I've settled for all new ball bearings and put them back in the old cages and used the original cups. Now I did find that the balls on the bottom were smaller than the top but I bought all large ones and this has worked out pretty good. The shims that were at the bottom had to be adjusted to be less than before to have the smallest amount of lateral movement in the main shaft. About 0.002" so that is good. Tomorrow is the weld the steering peg day and then shape it to suit the worm and then gap it to have the proper gap of side movement. So it is going along well so far. I have also found that the maker of the box is BISHOP as this is stamped into one of the end plates on the box. I feel that the box is not original to this machine as someone has wrapped a lump of 2" flat bar iron around a boss on the box and now uses a clamp to hod the box in place rather than using the 3 bolt holes to bolt it to the chassis.
I have fitted the original felt seal to the top of the steering column and I am already pumping the oil into it and it is soaking it up like I do a beer when I have the mind to, like right now!
So I will take pics of the progress, if any, as I go.
