Default Cast steel VS plate?

I have a steering assist kit for one of my army trucks. It is a pneumatic piston that pushes on the steering tie rod. I have one complete kit and have been piecing together another.

The stock mount for the air cylinder seems to be a cast bracket. It measures roughly 20x12. I need to duplicate this mount and have found some 1/2 inch plate to make up the main "body" of the brace. I will need to weld on a couple brackets to make it complete.

I was mostly wondering if a cast bracket will be stronger than plate steel?

I will post up pics tomorrow as I didn't grab any tonight.

It will probably be stronger than the cast. The only problem would be lawyers. The part you make isn't covered by product liability, so if something goes wrong you are on the hook. Personally, I'd do it anyway, they would probably never find out.

I agree with Norm on both points. The plate would be stronger as it has flex and the cast don't.

Thats whats great about the system, it doesn't REPLACE anything. If it fails I simply revert back to "arm strong" steering. It even turns itself off if the system air pressure drops below 60psi.

Thanks guys, I will post up pics later.

I'll agree with steel plate over cast for sure.

As far as the liability issues, it's an X military vehicle, your already on the hook.

I agree...

That is....

If your cast piece is actually cast steel and not forged... they can look surprisingly similar..

if forged it will probably be stronger than the plate...

but in any event, more likely than not it is so overdesigned that it will make no difference as a practical matter..

Forged means it was smashed into shape, right? It was not forged.

I had a job out of town fall in my lap. I will have to get those pics and post them up, but first OF COURSE, while out of town, the alt died in my car.

I have some MORE fix-it to do, and then I will update the thread.
