Take your time with it. Get a couple cutting disks, the thin ones, you'll probably only need one, but get a backup, they're cheap enough. Again - take your time, probably four passes. Draw out the circle you're cutting out - the bottom of an Ale Pail was the perfect size for me.

Or, send it off to BierMuncher - he'll hook you up

He stated he already had an angle grinder and it didn't do the trick. Maybe it was a cheapo?

Bad technique, or, more likely, thick cutting disks. Get the ultra thin cutting disks (1/32"). They eat sheet metal...FAST.

You could also try a reciprocating saw. They can be tricky at first, but once you get a feel for them, they do a nice job. More manouverable than a grinder.

Trust me, the thin cutting discs are the cat's a$$. You don't want to plunge all the way through in one spot then try to move following the circle. That's trying to get a 4" flat disc to make a 6" radius... not gonna happen. You use it to grind away the metal along your cut line in several passes. Even the one I did freehand left a top that is reusable just by tacking on a few SS washers. If you use a grinding wheel that's thicker, you'll just be there longer and make more metal dust and sparks. I cut three tops with the same disc.

I like the youtube tags soooo much:

By the way, I know my math is wrong.. it takes 2 minutes 24 seconds per cut.

I used a dremmel with about 10 reinforced cutting wheels. I sprayed the cutting wheel with water from a spray bottle while I cut. It did take a while, and it did go through lots of wheels, but it turned out really nice (almost as nice as Biermunchers ) Plus, I didnt have to buy any new tools. More money for beer!!!!

Nice jig - very nice job. For the inexperienced, you have to be very careful using cutting discs in an angular motion. Thin cut-off wheels are not meant to take any side force, they have a tendency to shatter and can cause serious damage to your body. I would recommend using a full face shield when doing any grinding. I've seen more than one messed up face from an exploded disc.

Actually a Dremel will do a great job at cutting a keggle.

You will need the EZ-Lock kit to do it without having to go through 30 cutting discs.



You should be able to finish the job with 3 to 4 discs. I did and it took about 10 minutes.

I just used a dremel to open up 2 kegs. Maybe 15 discs and 20 min each. I wasn't timing it but it wasn't to long. Nice smooth cut since the cutting wheel is so small.
