At this point you likely feel like a craft beer expert with years of experience. You’re beyond ready to brew your first batch on your own and yu can’t wait to amaze all of your friends with incredible brew. Nothing is going to stop you from designing and brewing the best damn beer the friend group has ever had the pleasure to enjoy! Only thing standing in your way is the critical lack of equipment in your garage. Online and in the brew store equipment for brewing that first batch can cost thousands of dollars! What if there was a more reasonable solution at a much lower cost with a little effort?
The answer to your brew problems just might be that old empty keg shell from the side of your house or potentially on craigslist. That’s right, that old stainless steel keg might just be your next brew kettle or mash tun depending on what you need. Now as far as conversions go there are some affordable kits out with grates used as filters at the bottom, but if you are going for a simple boiler it will be quite a bit easier.

To make the boiler you will most likely want to cut out the whole top circle using a setup like the picture above. This will safely allow you to cut an even circle for the opening. After that simply instal your preferential drain valve with necessary attachments for draining at the bottom of the keg in the side. Double check all connections and add spacers to assist with sealing where necessary.
From this simple boiler or mash tun you can infinitely expand and improve the system as money allows for it. Pumps for easy beer transfer and other non-essentials can be added later to the system by either attaching to the drain or adding a sparge attachment.
Go outside and brew a fresh batch this weekend, and follow me on Twitter @Tanner_Brews for more.
