Hi - I'm in need of the dimensions for the model T steering shaft where the steering hub fits onto including keyway
I'm making a custom hub for a speedster steering wheel that will screw into the said hub, I don't have a factory wheel to get hub dims from so hoping someone can accurately measure for me
The bore in a Model T steering wheel spider is not tapered, but does have a keyway. I may have the center portion of a spider (one with broken arms) that you could use for dimensions. I can look for it tonight after work.
Measure the shaft that the hub will fit on and make the hole in the hub approximately .0005/.0010" bigger.
The holes in the original hubs are sometimes difficult to measure because the hub is not just one piece, but a sandwich of several layers, with a hole broached though. Anyway, it makes for a somewhat crude hole. By the way, I speak of the later style wheels, not the early brass ones.
Thanks Don - that will be very helpful
I found the steering wheel spider with broken arms, but I can't remove the stub shaft and steering gear case cover. Anyway, here are your dimensions: shaft size is o.750" (3/4"), the key way is 0.1875" (3/16"). The length is 0.940". I have the top shaft soaking. I'll let you know if I get it apart for you.
John, I am doing the exact same thing and have the dimensions. Will PM you this weekend
Try this, I used one on a truck build. Worked great.http://www.speedwaymotors.com/Model-T-Keyed-Steering-Shaft-Assembly-3-Inch-Stubshaft,2035.html
