Leftover 2x4 Chest

About: My 30's have become a sort of renaissance for my tinkering and building.

Ever since I made my wife a small Zelda chest jewelry box a few years ago I wanted to make a larger round top chest. As usual I didn't want to spend much money though. So being the cheapskate I am I stated looking to the dumpsters on job sites I was at for work. I came across a dumpster that has the waste framing and found 8 almost brand new 2x4's and a few nearly complete cut off pieces. The "new" boards were mostly free of nails with a couple tag staples and a few of the cutoffs had random framing nails and some mud on them. All in all this project took the equivalent of about 13 full length 2x4's.

Supplies:

2x4's - qty 13

Brad Nails

Wood Stain

Wood Glue

Acrylic Paint

Polyurethane

Hinges

Leather Strap

Nail Gun

Handles

Masking Tape

Wood Putty (home made)

Black Paint

Step 1: Layout and Dimensioning the Lumber

I wanted the top to have a nice curve to it so I knew i'd be cutting some small angles to make the radius smooth. I did a quick google search and found a calculator for multi sided polygons. I knew approximately how large I wanted the chest (the radius). I also knew how small the piece could be an still allow me to cut them on my table saw ("a" in the calculation). I played with the numbers a little until I got a 46 sided polygon with about a 17 - 18" diameter. This meant there would be 23 wood slats for the top joining at about 7 degrees.

The chicken scratch written on my table saw is the cutting order for both dimensioning the lumber for the top's sides as well as the angled slats. Because these were framing 2x4's they have the rounded edges instead of the nice sharp edges you find on dimensional lumber. I sliced off the rounded edges and set some pieces aside once they were 1.5" x 0.75". 23 other pieces I continued with the process changing my blade angle to 3 degrees to bevel the sides of 21 of the angled slats leaving the last board on each side with one flat edge. Before I made all these cuts I tried the angles on a single board and prototyped it.

Step 2: Top Sides

I had figured the inside radius of the top (the radius formed by the underside of the boards that form the top of the chest) with the calculator on the prototype. I then glued together 8 of the 1.5" x 0.75" pieces using beam clamps and some scrap pieces to keep everything as flat as possible. I put masking tape on the scrap pieces to keep them from sticking to my finished piece. After the glue dried I used a compass to scribe the radius and cut it out using a jigsaw.

Step 3: Top Assembly

I used the two edge pieces and one keystone piece to frame up the top and just added the angled slats with a healthy amount of glue and two brad nails to hold them in place. Once all the angled slats were in place there was only a small 1/8" gap in one of the joints which I saw as a huge victory. I filled the gaps with some homemade wood putty (glue and sawdust)

Step 4: Bottom Assembly

The very bottom of the chest was assembled much like the sides of the top. Once the glue dried I cut it to size and sanded it all down. For the sides of the bottom half of the chest I was going assemble the four sides the same way with alternating sized slats to form a box joint at each corner however I quickly found that even after I dimensioned the lumber it was still irregular enough to make the joints not fit together correctly. So instead I glued the slats to the bottom one layer at a time. I still alternated the sizes to form a box joint at the corners.

Step 5: Sanding

Lots and Lots of sanding. So much sanding. I needed to get rid of all the table saw blade marks. One other note if you aren't familiar with this aspect of wood, typical dimensioned lumber used for furniture is pre-dried. This means that a lot of the moisture is baked out of it to keep it from warping after you've made a nice piece of furniture out of it. Framing lumber, especially dumpster grade, is not. So after this thing sat in my garage for about a week the top warped a little which left about a 1/8" on two of the corners where it sat on the bottom half. Not a huge deal, some felt pads on the corners would make it less noticeable.

Step 6: Staining and Decoration

So I forgot to take a picture of the staining but its pretty straight forward. After the stain dried I started adding the FLAIR. If your going to make a wooden round top chest there is really only one design that can go on it if you have any sense. The Wingcrest of course! I accomplished this by putting down a layer of masking tape. Next I put down a piece of carbon paper and then laid the design over that. I used a stylus trace the pattern and then used an exacto knife to cut out the pattern to make a stencil. Next I masked off the rest of the top and spray painted the design with some gold metalic paint.

Step 7: Sealing and Painting

Hey, you know what removes spray paint? Everything apparently! I wasn't going to poly the chest at first so I started to add some wax finishing paste instead but that started to rub off the design. So I re-masked off the corner that got erased and spray painted it again. After that I went ahead and tried the poly which then erased the rest of the dang design. *Long sigh* So I used some mineral spirits to remove the poly and left it all to dry over night. The next day I used some gold metallic acrylic paint to hand paint the design again. Finally I poly'd the whole thing. Thankfully poly doesn't remove acrylic paint. The inside of the lid and bottom just go a coat of black house paint.

Step 8: Hinges...Distaster...handles...

After everything was dried and ready I added some hinges. Now the top is fairly heavy, as tops go. So when I had the hinges on, before I added the soft closures, I accidentally let the top fall open backwards which snapped the top apart just above the hinges. I was so upset by this...the broken chest sat in my garage for two weeks untouched before I decided to sand the broken joint and re-glue it. I made sure to add the soft closures this time. Next I added some handles and lastly a leather strap to open it. There is no lock on the chest.

It turned out to be a pretty substantial piece of furniture and I'm fairly pleased with myself for building it. It currently sits in our bedroom holding my wife's exercise gear.

    Very nice. How heavy is it if it's made of 2x4s? What type of polyurethane did you use? I've had very good luck with Minwax water-based polyacrylic over painted surfaces before, although I haven't tried it over spray paint.

    I made a couple of chests so far and intend to make another one soon. I'll try out your calculations on the angles. I think i used about 12 degrees on my last one but I forget how i came to that number. Here is a photo of the last one i built and sold for $325. the metal straps and rivets aren't metal at all. the straps are some kind of pvc plastic strips i got from Home Depot and the rivets are simply hardwood wooden plugs. I painted them black then sprayed some silver in the air above them to give them sort of a spectled appearance. The rings are from garage door decoration hardware i got at Home Depot too, but unfortunately i can't find them for sale anymore. I got the reproduction old lock on ebay for about $10. I used some thin black metal chains to hold the lid open. I had the same thing happen to my first chest where the lid broke off. i cussed up a storm! haha. Oh and the rope handles had some kind of clasps that i used to physically attach the 2 ends of the rope on the inside instead of having 2 huge knots. Almost wish I would have kept it instead of selling it. I used the money to buy a DeWalt planer.

    Wow! That looks amazing. Worth way more than $325 in my opinion. Its funny how much sourcing materials goes into even small projects. I wander around home depot or Ace quite a bit not sure what I'm looking for but I know it when I see it. I'm always sure they think I'm trying to shoplift when I wander around for an hour and then don't buy anything. For the jewelry box I made I also made faux metal banding and rivets but I used thin strips of wood and upholstery tacks. A planer was a good use of the profit.

    thanks. can't make much money from craigslist and facebook I've found. everyone wants everything cheap. i'll need to sell on Etsy if i want to get a decent price. shipping is an issue there, though. that's a beautiful box! looks like a miniature of mine. haha. i like the design too. have you done much engraving? I've done some. I followed Dave Rhoten on youtube for a while and bought some of their router bits. did a real nice sign for my son with them once. wanted to do something like a jolly roger on a chest maybe. the bad thing about using the PVC strips is that if you nick the paint, it shows the white plastic under it. so i'd rather use wood or something that holds paint better. yours looks like metal. very nice. did you score inside of the wood at the corners to fit on the top curve?

    They are actually individually cut pieces about an inch long with beveled edges so they fit closer together.

    oh that must have been tough to do accurately. i just scored mine a little so it would bend there. needed a touch of wood putty to fill in any gaps that were left.

    did you wrap your felt around a piece of plywood or cardboard? just glued in? The first chest i did I used spray glue and just glued it onto the inside of the chest. didn't put any on the second one i made.

    Hi!
    A very creative use for scrap lumber! I wish I had read this before I made my (mine looks like a rather abused army footlocker...)! I'm currently saving up old pallets of a certain size for a similar project.

    Pallets are a good idea, the stringers can be cut down to get a rounded or curved top. I'll have to find a few more to make a full sized Pirate chest though ;o)

    I have a similar pirates chest that I am building but just haven’t had time to finish. Yours looks amazing and I applaud your use use of scrap lumber. One thing I did differently is that I started with a rectangular shaped ottoman that was being tossed. Then I used 1x4” lumber to build the chest around its frame. Saved me time and trouble.

    Thank you. That sounds pretty smart using the ottoman. Mine could definitely use some feet.
