Default How to cut a keg for a kettle?

I found a keg i forgot i have had for about 15 years,It stunk when i opened it up!.Yuck!.Anyway It's a 15.5 gallon keg i want to use as a kettle.Any ideas as to a good lid for it once a hole is cut in the top,and how to cut a nice clean hole in the top?.Also i want to use it for my first brew possibly,but I'm not sure if It's too big.I'm going to be doing an extract brew full boil,do you think It's too big to do a boil of six gallons?

I cut all mine with a grinder and cutoff wheel. It's not too big. I don't use lids. Here's a link to one of the many jigs that have been made to cut the top: http://www.homebrewtalk.com/f51/simp...ng-jig-143048/

Youtube is a good source for how to videos I watched a couple on this. Shows you how to make a jig to make a perfect circle.

As others have pointed out a angle grinder is a great option. If you happen to have access to or know someone that has a plasma cutter even better. As for a lid, many folks have used the cut out portion of the keg and welded washers to them to act as lids.

Don't use a lid for your boil unless you are afraid of debris falling in to your keg.

There is no such thing as too big!!! I use a 15.5gal keggle for all my extract batches, whether they are 5gal or 12gal batches. I assume you're using a turkey fryer or the like to heat the keggle, if that's the case you'll want to start with around 6.5gal to account for boil-off.

Happy Brewing!!!

i would cut the bottom of the keg and use the sankey port as a 2 inch tri clamp kettle drain! then drill a hole in the side of it and put a heating element in their wired for 240v 4500 amp. thats just what i personaly would do.

(thanks greenmonti for catching the missprint)

I bent up a funky looking piece out of bar stock and I tape it to the handle of my plasma. This way I get nice perfect circles. I'll put up a pic if you would like.

I understand the electric heating element idea which i like,I'm brewing indoors.But the tri clamp kettle drain part I'm not familiar with.Any pics of it?
