I might put in a relief where the bends meet.

Gary & James,

Thanks for the suggestions. You are both correct. As I said this was a training exercise we did to teach some CAD concepts. The design probably could be a little better. A gap where the flanges meet probably would be a great idea especially as it would also help make the part slightly (not much) lighter too. Possibly also could use some weight reducing holes in the vertical faces as well.

Anyone that wants to use it can feel free to do so, and also feel free to modify it and make it even better.


@Taylor: It would be really cool if AndyMark picked this concept up and ran with it. Might even send them the design.

Here is Revision 2 of the corner riser design.

I like the bracket in the first revision. If you needed it to be stiffer you could add a tack weld to keep the flanges from separating if there is a twisting load. When forming the flanges there are a couple of different ways to get the final bend. There is air bending with a 89 deg die and and coining with a 90 deg die. It all depends on the material type and the minimum bend radius for the material thickness.
