I am looking to build my own "wrought iron" fence. I have a welder
friend that will help me assemble.

The design I was thinking was a basic flat top rail with square holes
so that the pickets come through the top rail 4 inches.

The pickets would be 5/8 inch squares and the top rail should be 1/2"
thick. So I need to be able to make a 5/8" x 5/8" square hole in 1/2
in inch steel.

What is the best way to do that, considering I need to make about 100
holes in 25 feet of steel.



If your friend has a wire welder, I would make a round hole that clears the
corners of your picket, and weld it in solid.

The other option is a square broach. You would have to drill the hole first,
then run a broach through the hole in an arbor press. When you're done,
you'll have arms that look like Popeye.
