How straight are our axles?

[Vbb199]

Check out the SS axles, have some in a D60, bullet proof.

I plan on running some fatties , true track, and richmond gears, and aftermarket shafts to hold it all down on the pavement when i give her the juice, but thats many dollars away for now.

@wanderinthru,

I was wondering about that smooth surface at the dial indicator myself, like something is lightly rubbing there in the housing. Something is pushing on it there? Or rubbing on it inside the housing, but what?
Now you've got us all worried!!

I would think the SS axles would be a bit better steel. 1050 is nothing more than mild steel. Probably had some heat put to them to harden them a bit though, at the factory. dead mild steel would be to soft. You couldn't put much torque to them and they'd come out of the housing looking like a noodle. So they would have to have some hardening to them at the factory, wouldn't they?

No sir, if your talking about the 3 spots in the center of the axle there is nothing in the axle tube.

1050 can be heat-treated to probably 58-62 RC, hard, takes carbide to cut it, but lacks the nickel which makes it tough. Nickel based steels used to be a bugger to machine forty years ago when we used cemented carbide, but now days they have great inserted carbides, but let me tell you, it squeals like a pig when you turn it.

Strange SS axles are made with 1550, a carbon based nickel steel that can be heattreaded, here is Strange Eng page on it: https://www.strangeengineering.net/product/35-spline-axles.html/

This story sounds familiar. I think these axles are all like this. As far as balance is concerned, perhaps the moment of inertia or rotating inertia is
low enough it doesn't cause issues.

You're right.

How many RPM does an axle run anyway? (aluminum foil hat time)

Moments of energy need higher velocities than 1000 RPM to make any real difference. I don't think the SOP (seat-of-the-pants) would even be able to detect this ULF oscillation.

If you're worried (telling others, not you) just mark the high spot on the lugs so you can always park with that lug up so the sun and gravity can make the metal flow closer to centerline.

@59840Surfer,

Yeah right! Tin foil hat time is right. That's like a used car dealer told me that a tire will have a flat spot on the side sitting on the pavement over night. You bet.

@RaiderL ...

I bet you're too young to remember nylon cord tires ... huh?

They would get flat on the bottom overnight and need several miles of driving to warm them up enough to make them go round again.

I'm not a lathe expert so it was just a guess. It seemed logical.

We're not building watches so I'd still be curious as to what it did though. Not like every day someone has an axle in a dialed in lathe with a mic on it. Maybe a 'hold my beer' moment?

What is it your curious about? The first axle shaft was turned, fit and welded shorter. It looked like a banana in there. Just ran it slow and got it turned.
