How about 3/4 plywood Archie. Do you think that would
be stable enough?

Perhaps a strong, fine grain 3/4 multilayered plywood.
I/4" aluminum jig plate would be better, but very costly
for a one time application.
The main concern is not to allow components to move
during transport and welding.
Build it strong enough to withstand a one foot drop, and
it will be fine.
I have had to correct a few miswelded mounts,
(it ain't fun)
