Wish bones misc'
Can anyone give me some advice. As I don't know a great deal about materials, and I have been worried by the possibility of metal becoming brittle
when MIG welding. Can anyone tell me whether it would be better to braise.
Also, can anyone tell me which are the best top and bottom ball joints for the front wish bones. Transit - Cortina - Maxi etc as they have 2 or 4
mount holes on them.

You shouldn't have a problem with the joints becoming brittle with MIG welding as long as your not plunging them into cold water. Let them cool
naturally in air. I take it you'd be using Steel for these (no benefit using alu for the wishbones). MIG welding would be better than braising
because it is easier and wiser to have full penetration of the weld. What are you using for the front uprights, if it's a cortina upright use the
cortina ball joint, if its sierra I'd recommend the Maxi.

if you can , get them "Tig welded" otherwise mig is fine, like the guy says, let them cool in there own time, i used maxi ball joints, cortina
uprights, there lighter.

Brazing is basically a bonding process and is not suitable for stressed areas better used for joints where water and air tight seals are needed ie
pipe work or bicycle frames where the tubes penetrate the walls and the braze just holds them in place. Tig is ok but you will need to cut accurately
as gaps are very difficult to fill with tig particularly around tubular components. Therefore mig or oxyacetaline welding would be the most
appropriate means of joining. If you are still concerned do a couple of practice pieces hold one end in the vice and try to pull it apart or hammer
it apart you will more than likely find (if settings are ok) that you tear the 16swg tube long b4 you break the weld.

My wishbones are based on cortina ball joints as I am using cortina uprights. I bought Ford genuine parts and judging by the fitting diagrams that
came with them that little fold up bit is actually point less unless you weld addditional stiffeners to the wish bones but as the maxi joints don't
have them I reckon you can take your cutting disc to those if you are going for as light a build as possible. Personally I'm a fat bastard so don't
see the point  (note genuine parts translates as bloody rip off)

Cortina bottom ball joints are cheaper than Maxi types (approx £12/£15 each), so could be important factor.

Apparently Dunc paid £4.00 for his balljoints "from a local motor factors".
I know no other details but maybe we could get them there if they'll deliver!
Any chance of a phone number for them Dunc?
