RF attachment

I have been looking at the gallery pics but I can't tell exactly how the RF is attached to the stalk. I have a Jaster Mereel helmet that I painted up and I just drilled the aluminum stalk and used screws to attach it. I am kinda ok with this method but if there is something better...well, I would rather do that. So my question: Is there a specific way that this should be done or is there a tried and true method of doing this?

This is on an Asok helmet btw.

Thanks

i use two tiny little screws on all the helmets i've done, like 5/64" or something like that. as far as accuracy goes, i think that's what they did for the movies then ground the heads flush with the rest of the stalk.

My older ones were just glued on with some Goop. My current is a Master Replicas, so they did... whatever it is they did
