Do you mean 1/4 barrel? I'm making a Boka out of a 1/2 barrel keg (15.5 gal). Here's what I've bought:
5' of 2" copper DVW pipe - Local hardware store
25' of 1/4" copper refrigeration coil - Local hardware store
Stainless steel pot-scrubbers - Walmart

I am going to start by forgoing the Liebig condenser as I don't think its terribly necessary and it can always be added easily just after the compression-fitted valve. The hardest part was finding 5' of copper pipe, everyplace wanted to sell me 10' and the prices were all over the place.
Hope this helps!
I'm pretty slammed schedule wise right now. I'll get some pictures if I can, but it may take a while before I can get to it.
It isn't complicated though. I welded one of these to one of these. The previously-linked element screws into that. I took an air-conditioner extension cord and cut the female end off. I wired the black and white wires to the two terminals on the element, then used a rubber fitting to cover the whole thing for safety. The green wire I left long and hanging out with a screw terminal on it.
On the keg itself, I cut a hole in the side of it with a hole saw to match the inner diameter of the ferrule (second link above) as close to the bottom as I could. My keg has a rubber bottom so I had to come up just a little. I welded the ferrule to the keg. I also welded a small stainless machine screw to it.
To use it, I attach the assembled heater unit to the keg using a PTFE gasket and tri-clamp. I take that ground wire and attach it to the stainless screw nut, that way there is always a good ground attached to the keg. Put your wash in, plug it in to a 110v outlet, and you're up and running.
If you want to try to weld it all yourself, do some reading up on TIG welding stainless steel. It's a different beast. This was my first real welding project, and I chose stainless of all things to start with! It isn't pretty, but it is water tight and serves it's purpose. I learned a TON and hopefully will improve a lot when I start another project.
