I just got done building my keezer and since I know there are a lot of questions about collars around HBT I thought you might want to see my blog post and video about how I made it.
The keezer still needs some work before it's 100% done. Those perlick's ain't cheap, so I started with just 2 and will expand to 4. My old kegerator died about 8 months ago and I forgot just how glorious it is to have one of these things. If you don't keg yet, start filling your piggy bank.
Ask questions if you have them, either on the blog or here. Cheers
