Not 3G specific but I do see plenty of references to drilling out rotor retaining screws. This thing looks cool as long as you already own an air hammer and don't mind spending the dough on a tool you might not use that often.
Yeah, I know we can all live just fine without the screws.

 

I just use an impact screwdriver like this one and have no problems either. I don't have air tools. http://m.sears.com/craftsman-impact-...117x00001xlpla

 

^ I also use an impact screwdriver. Super easy and got the screws out without any issue! I got mine for 15 on Amazon so cheap

 

Impact screw driver.

 

thats nice! But no air impact hammer. So manual impact screwdriver from HF FTW

 

I use an electric impact driver. Has been working fine for me so far. I can see that tool working great for the really rusted ones though. Luckily it's not as big of a problem here in socal.

 

Yup, that's what I own too. And it works but the one for the air hammer does look like more fun to use

 

I've always used a 1/4" ratchet with a 1/4" socket and my screwdriver bits. Works extremely well. You can really push into the screw while applying tons of torque. We don't have a lot of rust here in Vegas though.

Here a picture of the same thing but with an adapter to use a 3/8" ratchet: MOARRRR TORRRQUE!

 

OK, OK, I know there are other ways to do it. I just thought that sucker looked cool. Sheesh !

 

i see no need for any tools once you get it out the first time. They are only in there for the factory assembly. I drilled mine out and never put any back in.

 

that tool is cool as shit. I would buy one for up to like $30
