What are Anti roll bars made of
Ok I know they are usually steel but is it some kind of special stuff, looking into getting one made or better if possible making one for my Autograss
project. I know they are available from suppliers but I'm tight (sorry i mean I'm a locoster!)

I use mild steel for the anti-roll bars on my grassers!
Use thickish wall seamless mild steel tube, its just the job.
Think the stuff I used was 11/16" OD by 3/16" wall.
You can use 4130 steel tube or all manner of spring steel grades, but mild will be just fine.

Morris 1000 Front Springs
If I remember the Morrie Thou had torsion bar front suspension.
I can't help thinking if these could be utilized as ARB's?
Too long, too short, too fat? Maybe they could be reduced in diameter in the lathe?
Thoughts anyone?

Old Renault 5 used them on the rear as well, they would be nice and soft if you can find any.
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

One of the newer Alfa's also had torsion on the front (75 maybe?) so should be a ready supply of material there!

If you can find one, try a Morris Marina anti roll bar. I shortened the arms of a Marina one and fitted it to my racing A40. It absolutely transformed
the car from being a natural over steerer to completely neutral and no roll whatsoever.
Failing that you can buy new ones in all different diameters for racing MG Midgets.

here you go, see the grey bar in the photo on the rear of my old grasser. Made from seamless mild steel tube, warmed with a big blowlamp and bent by
hand in a vice, no pipe bender needed.
Bearings are nylon blocks drilled and split through the middle.
The drop link hangers are home made and adjustable along the "blades"

Mild steel is fine -- spring steel is best but introduces heat treatment issues so stick with mild steel.
