Hello everyones,

On Decembre 2015, i bought this chassis with a lot of dust as a barn find ;)

Since those days, i try to make it as an exceptional piece of art from AYK.

I will post photos of this build started since February 2016 on next days.



The beginning:


One hour after delivry :

You're really good with the metal-frame-based stuff, mon ami !

Looking forward to more shine :)

Polishing your balls is a good place to start. :lol:

I like the Buffalo chassis, I had fun resto-modding my buddy's car--except for those round, raspy wheel hubs that bite into the wheel plastic. Finding a way to make 12mm hex hubs, modern wheels and axles work was a major pain in the a$$. If I ever do another one, I'll leave it stock.

You'll also want to check for bump-steer. My buddy's car had horrible bump-steer and I had to re-attach the tie-rods a different way to eliminate it.

Nice cars , I restored one last year. Very satisfying polishing it up , the only thing I did not like was the slop in the front steering knuckles , I ended up making up a new set of uprights with much tighter fit but I could not eliminate it completely .

My shinny balls have a good looking ;)

You are rigth, the front bump-steer is horrible with a very hard duress.

I think when I did my buddy's Buffalo, I reversed the tie-rods so the outer balls were installed on the bottom of the steering knuckles instead of the top. That significantly improved the bump-steer issue. You can kind of see it in this picture, looking at the left steering knuckle. I remember my buddy telling me, before I rebuilt his car, that it steered all over the place and was almost uncontrollable. No doubt the horrible bump-steer played a role. If every bump makes the wheels splay out like opening a book, the car will drive very unpredictably indeed.

On the one I restored I seriously thought about moving the front suspension top links back at the inner end to be above the rear lower arm mount in order to reduce the slop in the front steering .

I seem to remember a good amount of steering slop was due to those stock red ball-ends and little brass balls. I was able to reduce some of the slop by installing 4.8mm ball-studs in the steering knuckles and using 4.8mm ball cups. I did the same thing with my brother's Galaxy that I resto-modded; it also originally had dinky little ball-ends. The center pivot also was a source of slop, but that can't really be improved without totally re-engineering the steering system.

Nice work so far, Jerome! I remember cutting down that front body post too, because it's inexplicably LOOOONG for no real reason... :?

Makes the car look more like a Rhino than a Buffalo. :D

Wow, this build is turning into a show stopper! Really fine work, I'm envious.

It might be a good idea to re-check for bump-steer. On my buddy's car, I got very little bump-steer having the tie rod inners mounted on top of the pivot arm, and outers on the bottoms of the steering knuckles. I see you've mounted your tie rod inners beneath the pivot arm. Try it both ways and keep it whichever way has less bump-steer.

All that polished aluminum is pretty...gonna be a real Blingalo. 8)
