Dem bones dem bones (comments please)

I've just come in from making up a jig for my bones. I'm pretty happy with the idea althought it might need a little "je ne sais quoi" before welding begins. Any comments ( sensible) welcomed.
Here's links to my archive why the hell can't I get the pictures to appear?

Is there enough clearance for the large balljoint bolts on the underside?

It looks like it but I'll have to tack it all up and try first.

Hi

The bend in the Cortina b/j is a pain.

I cut mine off and drilled two more holes, then mounted it from underneath.

IMHO the plate looks better if it's curved.

I only say as the bones I got in an abandoned project (they always seem so good at the time), made by a 'professional engineering firm' welded the support piece on the edge of the bolt holes.
Pain in the yaris.

Yep the bend is a pain and that's why I've put in the small vertical piece. Yhe bone plate will be curved for strenght/stress as well as visual beauty. Where I'm not sure is should I weld both sides of the plate along the whole length?
The yellow item in one of the photo's is the hole saw I'll use in a pillar drill to curve the plate. But should i do it before or after the weldings finished?

you will need to secure the bones in a strong jig to stop them deforming a lot when you weld them. you may also want to use heat to stress-relieve them before taking them out of the jig. I messed up my first bones not knowing these things, see my thread "warped me bones, fix or cry?".

I cried.

I wold do the plate curve before welding in. You can have them clamped flat on a block then.
Iwould weld both sides depending on penetration. If you dont have full penetration then you may be left with a stress riser.
Hope the crap drawing explains better.

Depends on your welder and plate thickness. Rescued attachment weld.JPG

the maxi balljoint would seem a lot easier to fabricate a wishbone around, is there a reason why so few people (myself included) use it?
