Spent quite a bit of time since this fall reading through many build journals, searching for answers to questions, and most recently, digging into Steve Frederick's Build Manual. I have done a fair amount of construction, including gutting and redoing our former house, building all the cabinets, etc, etc, etc. Although I know I need to head into this with a different mindset (DO NOT OVERBUILD), this experience gives me the confidence to take on this project. AND it gives my wife confidence in me to do it! She will definitely help as well when needed.
I am basing the design on the Wyoming Woody, which fits as I am from Wyoming

We are building on a Northern Tool 5x8, and I have some guys in town cutting and drilling a tongue extension for me (Like X-Cubed and others have done)
Here are some pictures!
Messing with a few designs (Cub and Wyoming Woody)
First pickup load for this project (Floor which will be 1/4 ACX; 1x4 Frame with insulation, 1/2 ACX)
Used my router to make a scarf joint out of the 1/4" Lauan to make my template
I quickly realized that I was not very impressed with the Lauan!
