Bending 3mm plate?
goodguydrew - 22/10/08 at 09:42 PM

Has anyone go a good tip on how to bend the wishbone plate that carries the Cortina ball joint?
Can I use 2mm plate here? Use heat? Cut it and reweld at an angle?
Thanks.

Seen a few cut and welded.
Mind you, that was on ebay.

FBH and heat if you want.
Would not cut and weld.

What does FBH mean?

Why on earth not? If welds aren't strong enough then there's going to be a really big problem anyway!

Cutting and welding are perfectly acceptable and can result in much more accuracy than FBH/heat methods

I would use the FBH / Bend method, welding thin plate is hit or miss unless you have & are a very good welder.

I would be concerned about using 2mm Plate for this. IT IS A SUSPENSION COMPONENT not just a waterbottle bracket.

But personnaly I like to see everything strong as hell and over engineered.

To test my seat belt supports I picked the car up with a Chain Fall hoist attached to the bracket

I don't think he was suggesting bending OR thin plate. I think the thin plate was offered as another alternative. The way I read it the main choice was bending or cutting and welding.

Although I agree that 2mm is too thin, anyone welding a chassis needs to be able to weld 2mm or they are going to have a very big problem!

I'm glad to hear your seat belt mounting were able to take the weight of your car, but unless your car weighs several tons it won't really be a test of how well they would hold in a real accident.

I can't see the application here, but everytime I've had to bend 3mm+ for anything (I have a Land Rover too, often requiring substantial leaf spring brackets etc.), I've simply partially cut through with an angle grinder, bent to shape and then welded along the cut.

Exactly. Quick, effective, and usually more accurate than bending with anything other than the correct equipment
