Buy a gear with a 1/2" round hole (also maybe a keyway) and push broach it 1/2" hexagonal.
The push broach looks like this (this one is from Dumont):

It fits in either a
hydraulic or
arbor press.
The 20 tooth steel gear I did for other teams look like this before I broach them:

You know that intelligence test where you put the round peg, in the round hole and the square peg, in the square hole?
In this case you push with about 1,100lbs of force until the round hole chisels out to a hexagon
Proving once and for all - brute force can solve problems.
