I sent a packet of the drawings to some antique car enthusiasts in the UK per their request but unfortunately I have moved on to other projects. The unit does continue to perform nicely in my car. Thanks for the vote of support.
It’s been mentioned about Mitchels overdrive. I did a differential swap to taller gearing. Plus the Mitchell synchro tranny. This was good for a cruise at 50 mph topping out at 60 mph. But with old brakes,steering and nothing aerodynamic that was the practical top end. That was my Tudor. My 30 roadster has a tranny swap with a ford 4 speed overdrive tranny. Done by a previous owner. Once again good for over 60 mph but with min wind protection and old running gear about 50 mph was the top happy speed. What we love about the old cars is style and simplicity and rugged build. But it does limit the usable top speed.
Great video, I have the Mitchell synchronized transmission and OD in my 1930 Cabriolet. If you don’t have it the 6.1 head will give you a tad more power for the OD.
A friend of mine would work on antique cars, and he used Volvo overdrive units on Model T's and Model A's. They worked quite well. On his own Model T, he had an overdrive, and a Ruxtell 2 speed rear end. He had a Frontenac head and other period aftermarket parts for more power. He also used Honda Goldwing brake calipers and made disks that fit the model T so it had disc brakes. He had it up to 75 mph once, but never again, particularly because it was a 1915 with wood spoke wheels.
I keep hearing bits and pieces of stories about people who have done this before with these overdrive units. Very interesting. Thanks for the info and comment.
I have one of those in my A great unit I put a switch on the 1st and reverse rail. Never have it in overdrive and reverse together otherwise you will break the sprag clutch. They are hard to find. Also if uyou lift off the gas pedal momentarily when it changes into overdrive it is a lot easier on your drive line
That's exactly what I did: put an inhibitor switch on the reverse rail. Yes, the unit will try to overdrive the roll clutch in the wrong direction if engaged in reverse. Not good! Very interesting you did the same thing! Thanks for the tip and the comment.
After adding more ATF (I didn't know how much it took), the overdrive will snap your head back, when engaged, if you don't let off the throttle. However lately I've developed a nagging overheating problem and am currently trying to sort that out. That car had sat for over 50 years - something may be plugged. I'll consider an update. Thanks for the vote of confidence!
Very nice piece of engineering. You are a humble and talented gentleman. Bye-the-way, was there not a a product called Ruxell that was a two speed rear end that would directly retrofit into all of the A's ? Thanks for the Great video. There is just something about a model A. I love the sound unique to the A. Greetings from Ontario, Canada.
Thanks for the vote of confidence. I did a search and found "Ruckstell" two speed rear ends were available for Model Ts but I am not sure about Mod As. It utilized a shifter along with the clutch.
Great video! I have a model A pickup roadster and I also am contemplating putting an overdrive in it. I’m curious was your project more or less than the Mitchell o Erdrich system? I must say that the push button is a lot nicer than a whole extra shifter. Kudos on the success of your project and I’m interested to see how further testing turns out.
Thanks for the comment. I did the project for less than $900 but the trick is finding a usable OD unit. My car had NO shocks and that is why I limited speed so I am in the process of installing them and will get out there and tear up the road!
@@geraldirving6217 Since you're not averse to using British sourced parts, MG used an Armstrong lever type shock which I employed in my 31 Tudor.,even the bolt centers are the same. Easy-peezy-japaneezy !
I commend you for your engenuity Car parts from across the pond for an over-drive. On the open road with real world speed in the 70mph potential, you're wise to contemplate converting to juice brakes. Bendix type expanding shoe brakes(a-la Lincoln Zepher,39), are being reproduced for early Ford. They are far superior than 39-48 non-self-energizing type.
Usable Laycock overdrives are hard to find, so, no. However, at the request of an antique car club in the UK, where the overdrives are plentiful, I sent the the drawings of the project to them. Maybe they will do something. Thanks for the comment.
Right you are. The overdrive in reverse would force a one-way clutch in the unit to run the wrong way. I have installed an inhibitor switch on the reverse linkage to not allow engagement then. Thanks for the comment!
Great video y nice sound of your model a. I was looking for a video about the mitchell synchro gearbox and the only thing I found was this one. Could you please make another video about the gearbox, shifting without doubleclutch and the different ratio in the scond gear?
Yes, there doesn't seem to be any videos on the Mitchell synchro tranny. If anyone has done one, it would be Paul Shinn as he has covered about everything there is about a Model A. There is usually a waiting list to get this gearbox and, because it shifts and engages so nice, I can see why. I'll consider another video. Thanks for the comment!
Your car looks identical to mine, if not the exact color combination it’s very close. I notice you are running 1935 wheels. I just purchased a set for mine. What size tires did you go with on the 35 wheels? I haven’t purchased tires for my wheels yet. Also, is your suspension stock? Not lowered? Thanks…
I have this unit in all 3 of my Model A's. They work great.
Very good! Thanks for the comment.
Great video. I’d love to see more of the build and design drawings.

I think your a genius. That was one of the best videos I've ever seen. 😮
Thanks for the compliment. My son's GoPro was a big help.
Very well done, thank you. 1928 Ford Sedan owner.

I agree, how fast do you really want to go? Thanks for the info and comment.

Great job keep up the videos and by the way you got a beautiful home
Thanks for the compliments!

Can you please give some updates, you are imaginative and creative you should do more videos

Thanks for the comment and brake info! I will definitely keep it in mind.
Amazing- I like the electric shifting! Have you given any thought about selling these

Great Vidio... i have the same Overdrive in my Volvo Amazon and also i have a Ford Model A...
I need a adapter ...🤔🤔
Thanks or the comment.
Very interesting. How fast will run or safely drive?
My 30 model truck needs one bad.
Thanks for the question. I've only had it up to about 55 mph and seemed to have acceptable handling on our uneven roads. Good shocks help.
Using the reverse in overdrive will trash the overdrive unit. There is a lockout switch in the Volvo transmission to prevent this from occuring.

Yes, those are '35 wheels and the tires are BFG 600-16. The suspension is stock but maybe a little "settled." Thanks for the comment.
Should have bought a Mitchell overdrive or a borg Warner made for model a
Remember where I said "more money than brains"? Thanks for the comment.
