Thanks for the help guys.
I have planned everything out through sketches on paper, with lots of measurements and planning. I have never built anything like this before, and I wanted to be prepared. I went to Home Depot today, took forever, bought the wood (used all whitewood/pine), bought most other things I needed to build, and started the build.
It actually went really smooth. I mitered the top trim pieces, and I think I have a pretty good start going. Ill post pics up tonight when I upload them. Pretty happy for zero woodworking skills and very limited experience in anything like this.
So far, I have the top, the trim on both the top and bottom of the top, trimmed the bottom frame, and built the coffin!! Its not perfect, but a perfect start to a life of ever improving on my keezer design. Like I said, pics to come
