Yeah, I meant something like that.
I think it should work OK , but I would prefer to weld the whole outside.
We are trying to save the top that is on it now, so welding it all would likely damage top material.
If on the other hand we can't work the top edges correctly I will remove the whole top and weld it. Then install a new top.
I already purchased one just in case we fail.
If we get it I will resell the top.
