Bought a group of late '60's / early '70's junkers.  A few had this interesting front axle. 2 3/4" long.  3/8" flats on opposite sides on ends.  Interesting part:  1/8" axle with center machined to 3/32", I assume for less friction in an axle tube.  Was this a production item or was this guy a good machinist?

My guess would be that that was a part made for a different piece of equipment that someone noticed would work as a slot car axle.

I tried to get someone with a lathe to do something like that for me.  It was an F1 car, but the turned bits were just a half inch on either side of the tranny so the gear could still be centered.
Would have been cool!

It appears that the fillet radius on the left end of the reduced diameter is different from the one at the right. I would say home made. If it came from a wing car, it might have been an attempt at weight saving.

Good eyes.  The one 1/8 end is 2mm longer than the other; the other similar axle has a longer fillet;  so home-made makes sense.  Makes one wonder, though, why some company wouldn't have produced something like this.

 

Three of the five cars are home-made steel wire, most with 1/8" axles, and with various Dynamic handling bodies with minimal spoilers.  One has an NCC20 arm, another has white epoxy on the winds, so probably Dyna Wind; in other words, pre-wing car.

I recall when a local New England racer was selling 3/32" axles ground to a triangle for weight savings.

IF that axle is a drill blank? I would think it has to ground to size, not turned. At least that's the way I would approach it.

 

Pre 3/32" (1969/70 ish) axles so it would allow you to move the motor back and to a shallower angle.

This is a fun job. (not really)
