well, make some progress today. The hardest part was dealing with the imperfections in the wood. For example this panel bowing out. I couldn't really clamp it, and the brads didn't really bring the pieces together all that well, for example:
Things seemed to line up okay, the top in this case is just placed on for looks. I'll have to do some work to get it to fit well, but should be doable when the time comes:
Last, I started sealing up the seams, where the caulk wouldn't block future pieces. There were definitely places that you could see a crack of daylight in the joints, so I'm hoping this will make things nice and air tight.
Unfortunately, I got stopped tonite as the next piece wasn't cut yet, and the next piece after that didn't fit all that well and will need to be trimmed. But, progress is good!
