It seems I saw somewhere that the spindles for a 26-27 were different from earlier years. Is there a difference and what is it. Thanks
I had just found that out myself too, the 26-27 has the axle a little higher so the car sits lower.
Here is a picture that explains all . Thanks to Ken. Regards, John
The angle between the spindle and the king pin is also different.
Ken, if that was the case then the camber would be different.
Since they are different the camber may indeed vary between Fords of different years. There are other variables in wheels that may have caused the change in spindle angle.. Early non demountable front wheels were dished, while newer demountable wheels were straight. If the tires were supposed to meet the road at about the same position for both types of wheels, the older dished wheels needed more downward angle of the spindle than with the later demountables.

Roger, I'm curious as to what you mean by early non-demountable wheels were dished?
Roger means that the spokes were not in the same plane. The hub was slightly puckered toward the spindle.
Old wagon wheels were the same way.
Should the early parts books reflect this in the spoke being different to later de-mountable ones?
Sorry ment non de-mountable ones.
"Ken, if that was the case then the camber would be different"
The camber is different, aprox 3º on the earlier ones and aprox 2º on the "improved cars" (26-27s.)
Ford didn't give the camber in degrees, only in inches, 3" on the earlier cars and aprox 1 15/16" on the improved cars.

Thanks Jim, Now was this the case of T non demountables? and if so should it be as obvious as the drawings, for the life of me, I can't see it in my early wheels! but then again I'm closer to the box than the cradle!
Kerry, from the encyclopedia:
http://www.mtfca.com/encyclo/U-Z.htm#wheels
"Non-demountable front wheels which used 30 by 3” tires were apparently dished throughout production. Wheels which used 30 by 3-1/2” tires (demountables and 1926 non-demountables) appear to have not been dished."
Canadian and thus Australian non demountable front wheels were 30x3.5, perhaps that means they weren't dished?
Thanks Roger, after reading that, it must be the case.
I don't think Ford dished the wheels. That would have to be accomplished by the spokes since the hub faces are parallel. I've never seen spokes with an angle on the inner and outer faces nor the dowel end. Besides that, the early drawing (wood felloe) shows the spokes centered between the felloe and hub and on the same plane. There's no offset or "dish".
Sounds like another old wives tale.
