I did a very similar project, entirely out of cedar. I stained the wood (not fully done in these shots).
Mine was 24" high x 26" wide x 56" long. It’s a tad too big. I think I measured originally and planned without adding the outside legs.
Cedar was a bit of a pain to work with as I was used to much harder woods, but it still made a great box. It’s still on my deck right now holding all my gardening stuff. It isn’t super strong though. I ended up doing a rabbit for the slats and nailing those slats in with an air nailer. This worked great and I would suggest it, we have the tools (dato) at VHS and it looks great. The frame is glued in place with some squares on the inside corners for support. I never did make a lid.
I kinda figured it out as I went, and made some mistakes. If I were to do it again:
- Make it a bit smaller so it would fit through doors easier. I think if I move I’ll lower it down on a rope.
- Maybe Not make it ENTIRELY out of cedar, especially if I wanted to sit on it. I’d make an internal frame out of metal or treated 2x4. There are others here who do wood far better who might have better ideas though.
- Not gotten as crazy as I’d planned with the jointery, as cedar does not work like that. Cedar is super soft. I spent a decent amount of time sitting at VHS frustrated as all hell, considering scrapping the entire project, after my joints were all failing.
- Planned and built a lid. I never figured out a hinge (and I never left myself a good place to attach one)
- Maybe followed some actual plans for my first big wood project like this.
I was also surprised at the cost. When I had to get all the screws, wood, glue, stain, it was actually near the price of the ones you can buy a kit for at home depot. But it is far prettier and I do love it.
Good luck! You got it.
