David…thanks…and I think your looking at the back panel.  1st photo shows the front and the lid/door and the 2nd photo shows the rear panel.  The rear panel is glued and screwed into place.  The screws are countersunk and plugged.  The bottom rail on the front is treated the same.  I guessed at this by looking at this photo on Paul’s website.

Thanks George…I looked really hard at Tom Fidgen’s tool chest.  He did a video series showing him building one on youtube, here.  It didn’t quite meet my needs though.  I needed this tool box to hold a 2 foot level and a full size framing square.

In the end, I just like the looks of this style better.

Done! Finally got this tool box completed. It turned out pretty well. Learned a lot and had fun. Used the cheap hardware from the home center. The worn thru areas of paint started as an accident and then I decided to go with. I’ll be less worried about the first scuff or ding this way I think. The finish is soldier blue milk paint with shellac and wax. It’s got that “lived in” feel to it.

What I learned:
1. Work flow is very important. When Paul presents his tool box the work flow is the important thing with a project like this. Several times I back tracked to complete something.
2. Build the rear panel and door a little oversize so you can trim them to fit. You don’t want to have to take a couple thousandths off the entire case, trust me I know.
3. Installing three hinges is a pain!
