I have a vise, torch, and big hammer in my shop, so I could probably make a hook from steel that would work. But I don't know what you have available.
If you have a jig saw or band saw, you could cut a hook from sheet aluminum rather easily. You might need to order the aluminum though, if you live in a small town. 1/8" aluminum will probably work, if you design the hook so it has sufficient width.
Also, not having any idea what you are going to attach the hook to, it's hard to be more specific about how you could make the hook.
and plywood works too!
