Holes drilled into the sides for the set screws. You can see where I ground down the sides to make them flat.
Tapped the holes with a 1/4" 28 NPF tap.
Set screws are in and ready to go!
Drilled a 1.1 mm hole for the gas orifice.
About a mile of Teflon tape later all of the parts are assembled. Later I took off the needle valve because I couldn't get it to sit right and it kept leaking gas. But there is one on the regulator, so no problem.
