Single seater anti roll bar fabrication.
Discussion
I want to make a new anti roll bar for my formula ford 1600. I have the original to copy, but I would like to experiment with different lengths and thicknesses. As a matter of interest, which part is responsible for the torsion - the arms or the part that the arms attach to?
I can get the machining and tig welding done, bu has anyone any idea on what material to use. The existing one uses 12.5mm arms and a 13.5 horizontal bar between the two thicker parts. Best to see picture.
The standard ones do not appear to be heat treated and seem to bend fairly easily, leaving them out of true. If they get heat treated though, how does that affect the stiffness?
Any help gratefully recieved!
Thanks,
Andy

the part the arms attach to is reponsible for the torsion, with regards to heat treatment it all depends on the type of heat treatment done, if you just want to experiment with different stiffnesses i would worry about heat treatment too much.
I dont know what the antiroll bar set up is like on a ff but if there is scope for it you may be able to alter the stiffness my using different length arms which alter the leverage on the bar.
Finally if you can get stuff fabricated it might be worth trying to get a blade type antiroll bar which would let you adjust stiffness on car

Time to get the engineering formulae and calculator out.
As above, its the centre piece that provides the anti-roll in torsion, rather than the arms themselves ... for calculation, assume these arms to be rigid (even if there is some bending going on)
The heat treatment of the steel is only one part of the puzzle. The type of steel used in the first place will also play a roll (no pun)
Long and short of it. Have a play with the numbers and do some maths and scribbles, however ultimately accept that its wuite likely that people with a lot more experience, testing and expertise have been there and done it, so stick with the off the shelf replacement parts (if such things are obtainable)
