Not quite a build thread....

[Johno]

Well I made my new wishbones today....
Got a bit of a panic on at one point... Started welding my tube to the bush and decided to slide my inner threaded adjuster in to see if it still fitted.
Well that was a bad Idea....Slid in easy and all of a sudden it stopped moving.
I even told myself before making them at no point leave inner adjuster in when welding.....dohhh.
I eventually got it out with a bit of heat going over the weld with the TIG and a tap from trusty old hammer...
Lesson learnt.


Here's a piccy of the finished product.........



The inner adjuster is made from mild steel with a 16mm dome head welded to the flange on the adjuster which is tapped 14x1.5mm to suit the 325 BMW ball joint which has the correct taper for the MX5 upright.
Adjustment for camber can be acheived in situ on the car with an Allen key and 22mm spanner without removing any parts.
Caster can be altered via the "Rose Joints" which turned out to be pretty easy. Just remove the bolt and spacers and turn the rose joint in or out as required within the suspension bracket.
Each end of the adjuster is a stainless machined washer to stop the locking nuts chewing up the paint/powdercoat.




All radiuses are 2.5mm where required for IVA.
The rose joints are 12x1.25 fine thread and are "Ultra High Strength" with misalignment washers both sides for optimum adjustment.
I've moved the adjuster back 5mm to increase caster by about 1.4 degrees.
