Model AA 3 speed and auxillary
Saw a 28-29 chassis in scrapyard and could not help myself. Transmission shifts as does auxillary. No practical use for it, other than belting to my old blacksmith drill, perhaps.

Re: Model AA 3 speed and auxillary
That second gear box is a Ford Dual-Hi that was married with the three speed transmission from a Ford car. Standard issue for 28's and early 29's. The Dual High gave you an under-drive.

Re: Model AA 3 speed and auxillary
Thanks, that what I understand. Just couldn’t let it go to the torch and come back as a Turdota. May find a way to belt it to my old 2 speed champion drill press. That would give me 12 speeds!

Actually, several internal gears on the commonly used machine tool "Drive-All" are the same gears used in the Model A. Three forward speeds - no reverse. Joe K

Re: Model AA 3 speed and auxillary
I have often thought that a "Dual High" could be incorporated into a torque tube - but done "backwards" to offer an overdrive.
By the time you are done, you may as well buy a Mitchell Tranny. I have observed that the dual high seems most closely associated with the three speed Model A transmission. By the time the four speed was offered, the low end gears were considered low enough so the dual high wasn't required. Instead by then everyone was buying a Warford for the Model AA - which offered an overdrive. The special parts to mate the Warford unit to the Model AA were included in the "Green Book" (1947) Including the special mix/match universal joint. Joe K

Re: Model AA 3 speed and auxillary
I’ve seen threads on the HAMB where people have contemplated running it backwards. Didn’t see that anyone did. I just have a soft spot for the old iron. And here I am trying to deplete my wares….

Re: Model AA 3 speed and auxillary
A member in our club had a '30 coupe with a "reversed" dual high trans he ran for 30 years with no problems. He has since passed away.

Re: Model AA 3 speed and auxillary
These must have been ideal for local service trucks in the day. Like coal deliveries, and tow trucks.
