anti rollbar

[mediki]

I need to make a antiroll bar for a trike what material are they made from,can it be bent easly and what thickness do I need.

[guydewdney]

f;ing aaaard spring steel.

no.

15 to 20mm is the rough size. go to a scrappy armed with a set of spanners (and definately two 13's). Thay arnt difficult to take off. Dont worry about the drop arms / bolts - they are very cheap from most motor factors (like a fiver each with new rubber bits)


Find one out of a car - pref the car that the rest of the suspension came off...

If thats not enough, theres usually a higher rated one off a higher spec / sportier version (e.g. a vauxhall astra 1.3 has a thin bar, a 2.0 GTE astra has a thick one. (oo er missus)) - 2mm diameter change makes a LOT of difference.

only problem is that I have shortened the axle so could do with one made correct width

[guydewdney]

one off a nova/corsa/fiesta? pick a diesel if not a sporty one..

your next best bet is to shorten the arb yourself - but put a BIG sleeve over the cut (thick, not long)... but i dont rate its chances.

maybe get maxpower or performance xxxx (as in ford/bmw/vauxhall whatever the axle is off) and see if theres any specialists who make them - but ive never seen one...

good luck

Or get your ass to the library and see if they have a copy of "the Race and Rally Car Source Book" by Alan Stantiforth or his "Competition Car Suspension Design".

Either of those will tell you all you need to know to build your own adjustable one.

Or you can buy them from Haynes/Foulis

I posted this question a while back and Blackjack gave me the same advice which proved to be just what I was looking for.The book mentioned is very informative.

I used 18mm silver steel which has good strength and is used in engineering for torque shafts, boring bars etc. I made a rough jig of the shape I wanted then gave the bar a good heat at the points I required to bend it at. Not to lessen the strength of the bar at the points I heated, I wrapped the heated areas in a fireproof insulation blanket in order to slow down the cooling rate. Do not cool them in water as this will make these areas brittle.Then I drilled the two ends and tapped the holes to accept the bolt that passes through the eyelet of the rosejoint. The droplinks to attatch the roll bar to the lower wishbones were made from the same bar, cut to size and drilled and tapped at each end to accept the rosejoints. Two drilled lugs were then welded to the wishbones to accept the bolt that passes through the rosejoint eyelet.Finally the anti roll bar was attatched to the frame of the trike using 18mm nylon instrument pipe clamps. I got the rosejoints and the pipe clamps from RS Components and the bar from Cromwells. Hope this has been of some use to you
