The keg i will be using to make a keggle is about half full of old beer. I was watching Bobby's angle grinder cutting video and reading some threads about leaving some water in the keg to help deaden the noise while grinding.

should i just leave the beer in the keg and start cutting? or there is an ideal amount of liquid to have in there for this?

I usually fill kegs with 1-2 gallons of water before cutting the tops off.

Personally I would depressurized the keg, remove the spear, dump the beer, and then start grinding.

Removing the spear does not take too long, and will make dumping the beer easy. It sounds terrible smelling old beer for the 15 minutes it takes to cut a keg.

I would remove the spear, dump the beer, then fill to the top with water. This works best for minimizing noise.

I agree with dumping the beer and and adding about a gallon. As far as the noise goes I ended up wearing some ear protection like you'd use if you went shooting.

I wouldn't fill the keg up all the way just in case you accidentally dropped your cutting tool in.

+1 with all the above.
depressureize, take spear out, dump stinky beer, add a bit of water, cut top off.

I actually really enjoyed the deafening sound when I cut mine this morning They were empty. Oh well, I still have most of my hearing. But hey, I DID use eye protection, and really that's what counts.

All of the above, and wanted to add that you may want to let the pressure off with the keg on it's side pointed away from you. I have been blasted in the face and sprayed beer all over the place before.
