The Model A Leafspring Debacle Part 2

[@donbosco6081]

Your subtle humor is hilarious!!! Thanks

[@poulbjerre181]

I love the under car photage. What beautiful geometry! Form follows function. The wishbone, the axle and the spring working beautifully together in perfect harmony. If you like and appreciate good engineering, this as good as it gets. Triangular shapes for rigidity and a parable spring with triangle fixtures for flexibility without loss of stability. I get tears in my eyes. :-)

[@AstraWerke]

It's amazing how much is going on underneath the car, even on what appears to be a rather smooth bit of road. The wheels are all over the place - makes you wonder how it's possible to even go in a remotely straight line xD

[@mafcawebmaster4237]

Well done. Enjoyed the vintage footage of cars bouncing over plowed fields!

[@AstraWerke]

Thanks - those are actual Model B Test Drives conducted just outside the Rouge! kzbin.info/www/bejne/moPSg6qAmc9rnrs

@@AstraWerke Nice footage find!

Actual Ford test track, Dearborn. File film.

You did a great job on that spring set up, looks great, must ride a lot better too! I know what you mean about the shock links, my 29 Coupe was missing the two rear shocks and the front shocks were toast. I decided to replace them with a kit that uses modern shocks, it cleaned up the look and made my car ride much better.

[@jonprain412]

I love every one of your videos!

[@conrad1468]

Wow!! Lots of tension in those rear springs.

[@michaelcherry8952]

Well, on the plus side you should now be able to remove and replace the rear axle blindfolded! :-) 7:27 another advantage of the GoPro is you get that distinctive Model A starter and exhaust sound. Nothing sounds quite like it. Love the vintage test track footage. Given how bouncy these things can be with those transverse leaf springs, that must have been an "interesting" ride for the drivers. Hope they were wearing hard hats! Thanks for another interesting video.

[@AstraWerke]

Especially speed bumps are a fun experience with this type of suspension. The downward movement of the front wheels upon leaving the speed bumps has a recoil effect on the rear spring which catapults you upwards once the rear wheels touch the bump. With no seat belts, that's where the term "knock on wood" must have originated: Your head hitting the roof beams xD

[@JalopiesDannerr]

A good idea is to bevel the ends of the spring leaves, as the sharp edge will dig into the underlaying leaf, over time. Next time, reach out, as I might be able to help finding parts - I'm a bit closer (Dänemark). :-)

[@AstraWerke]

I did bevel the leaf ends in part one. Maybe not as heavily as some do, but certainly enough to smooth up the hard corners. I'll keep your offer in the back of my mind, thanks alot :D

[@mosfet500]

Nice job!

[@FordModelA-kp9ko]

Super Video. Natürlich hattest Du den ersten Federschaden weil eine Feder fehlte und die Andere dadurch überlastet wurde. 6 Stunden für den Job ist klasse! RESPEKT. Die "modernen" "Dogbones" an den Dämpfern hab ich auch. Ich hab alle aus USA mitgelieferten Schrauben und Muttern weggeworfen weil die billigster Dreck waren und beim ersten Anziehen abgerissen sind. LG Christoph

Under car cam, great idea. 31 45B

[@Clifforddward]

HaHa!...loved the vintage test track scenes....

[@Rob-hw5wr]

Unlike the previous owner you didn't just say, "close enough".

[@AstraWerke]

"Close enough" was fine for a showcar. With the amount of driving I do, that spring would probably have broken again pretty quickly in that cobbled-together spring pack

[@Blurredman]

Did you feel any difference, afterwards?

[@AstraWerke]

Well, it is a little bouncier down rough roads at low speeds, but most importantly it seems to stick the road more. Pothole-infested roads were more of a "point the car in a general direction and hope it works out" before, now you can maneuver it quite accurately through the bumps.

[@juslitor]

Could it be that the drum in stuck on the brake shoes ?

[@AstraWerke]

I'm pretty sure it's not - the wheel was free to rotate, after all.

[@jrom213]

@@AstraWerke sometimes there is an edge on the inside of the drum. It is where the shoe doesn't touch the drum and therefore does not wear out ... could this edge get stuck on the brake shoes?

[@AstraWerke]

@@jrom213 Well, it was no problem to remove it the first time I did - plus, a bearing puller would have at least gotten it off the taper and you'd have been able to wiggle the drum about for the amount of play that the brake shoes have in their mounting. The drum was rock-solid, however.

[@Rustinox]

Indeed, ré do is always faster than do :-)

[@AstraWerke]

Especially taking it apart the second time felt like a Formula 1 pitstop - we both knew exactly what to do, one unbolted the U-Joint, the other unbolted the spring - I hope I won't have to, but I'm sure, the third time would be even quicker xD

[@paulwomack5866]

Just posting on this video as the only way I know to get a message to you: Are you OK? Did you and yours escape the flooding?

[@AstraWerke]

We live on a hill, so everything's fine here. Sadly, that can't be said for downtown - or other cities, though...

[@petarraykov9059]

Must have become much harder suspension now.

[@AstraWerke]

It's a bit stiffer, but most importantly, it seems to stick to the road more when going over bumpy roads now. Before, I could only point the car in a rough direction when going through a series of potholes - now, I can accurately maneuver it straight through the bumps.

No entiendo lo que dices pero, gracias por los videos , saludos fraterno desde Perú 🇵🇪 ( Perú es un País del continente de América del Sur )

[@AstraWerke]

Muchas gracias, Ford produced the Model A in Argentinia, too!

[@lloyd4768]

I think you're going to have to heat that drum up to get it off.

[@AstraWerke]

That'd probably help - but as long as it is this tight, I don't see a need to do anything about it :)

[@fergusonmfgijsm9714]

If yoy needt to get the reare axel of again mabe you can put a overdrive in it

[@AstraWerke]

I could, but I won't. Having just the three speeds is part of the challenge to me

[@fergusonmfgijsm9714]

Thats also the whay how i like it :)

[@the_hate_inside1085]

Does the spring ever bottom out against that steel bracket it is mounted inside, if you hit a major bump?

[@AstraWerke]

To be honest, I'm not sure if the wheels would hit the fenders before that happens, but it would take one hell of a bump to provoke that to happen.

First ride under a Model A!!!

[@HorsepowerDashcam]

Wait you have friends?

[@AstraWerke]

I pretend to have friends, they pretend to be them. Win-Win :)

[@HorsepowerDashcam]

@@AstraWerke Ah I understand. They probably only pretend that to be allowed to drive your car

[@AstraWerke]

​@@HorsepowerDashcam Maybe I only let them drive my car so they have to cut videos they took while driving ^^
