urgent watts link help needed!
i'm about to start making mine today, and was about to go out and get the tube cut and trimmed in a lathe, but how should a watts link work? i
always thought the bars should overlap so the swivel in the middle is like at 45 degrees like A, but the racing ones seem to have the swivel vertical
like B, is there any difference?! would C be a problem?
i don't like C, so i'm not doing that, but is there a best way? i don't think it makes a whole lot of difference but i want to be
sure

Pivot should be on axle case.

All you need to make sure of is that you don't run out of movement in full bump or droop. A gives you the most available movement but unless
you've got miles of wheel travel B should suffice. All you need to do is a scale drawing or the trig.

The whole link to Wikipedia has other useful information.

wheel movement will only be like an inch or so normally, 2" at the very very most.
think i might go for the swivel being vertical then, since i've not got the swivel bracket in yet (ordered today)vertical will be easier to work
out for the length of the bars i guess...
yeah, vertical it is. i always had it in my head it should be a Z shape
minitici, the swivel can be on the chassis or axle. its on the chassis in my case

ah, the full link shows it both ways, one way is the drawing showing the swivel verical, and the ford ranger is at an angle, so i guess it
doesn't matter a huge amount?

The really important thing is the two radius rods are the same length and parallel to each other.

Where would we be without the good ol' Wikipedia, eh?
It completely overlooks the fact that most serious racecars that use(d) a Watts Link, put the crank/pivot on a bracket on the CHASSIS.
Unsprung weight and all that insignificant stuff.

^ thats where mine is!
yep the bars will be the same length (got rose joints in the for adjustment) and should be parallel... i may have welded on the axle brackets without
seeing the centre pivot... they won't be far out anyway. not noticable, and will still be better than a panhard rod

well conventionally theyre shown at 90 degrees to each other , since that should be the ride height its set at , as long as they work equally its not
too important
