a pair of nuts

can be a huge difference.
photo shoot. .rat rod.. missing the jam nuts on the radius rods.
damn foo pay attention

can't stand the crappy grinder work. And the holes sleeved with the tubing sticking out past the edge
That's just being lazy. Nice clean job routing the plug wires. Not.
Don't do this !
and there is a engineering formula for holes.. even sleeved holes. Just too close to the edge.
I really can't understand why anyone would think this "looks cool"

here all show you some welding and grinder work.
John did this one up on a 32/A frame awhile back.

the inside is a separate piece welded to the stamped rails. The inside edge
is a welded and ground corner
smooth boxing plate welded on 1932 rails 

the belled holes are properly sized and spaced
the upper inside edge is another welded and finished corner
That my friends is grinder work !
