What I was taught in the Apprentice School, long long ago. Drill a hole a
piece of sheet which is several threads deep, tap with the appropriate
thread. Hacksaw through the tapped hole. Put your threaded rod through
the tapped hole, hold the sheet in the vice.

IIRC I still have the screw clamps I made there unfortunately, Whitworth or
BFS & BA. The ones they made us make had several tapped holes in a line,
sawn through and a large hole with 1/8 of metal round it to make the clamp
flexible enough to allow threaded rod to be inserted.

Hope that is understandable ;-)

Actually it's not!
Why do you need to hacksaw through the tapped hole?
Does the sheet remain flat?
Do you put a nut on each side of the sheet, or what stops the rod
rotating?
