I have made a few of these over the years, and if i had the space and utensils, I would make it out of wood, as the construction would be the same.... for the curved top I would probably use some flexi ply or similar...
Anyway for your viewing delight, a cardboard treasure chest.... and an amusing picture of me as a pirate just because its fun and semi-relevant! ( I also made that costume and hat too!)
Step 1: Ahoy Thar Ingredients Off the Starboard Cap'in
- Glue gun
- Knife or Scissors
- PVA Glue
- Tissue paper
- Pen/ Pencil
- Paint brushes
- Duct tape
- Patience... I don't have very much of this... so i made sure I completed it quickly ;)
Step 2: I Don't Like the Cut of 'is Jib! Measure Him Up!
So you should end up with 7 pieces 5 of which should be rectangles, and two should be half cut circles....
For the lid covering, you will need to make sure that the card that wraps around your lid sections is as wide as your front and back sections, I just had no way of drawing this.
to make the lid sections, I drew around a rounded object to get a uniform curvature
when you are satisfied with your measurements, it's time to cut out your pieces.
Step 3: Lift the Hatches Boys!
I found that it was best to glue the rounded sections before i cut the roof covering to size, as you will need a few inches to form a hinge between the two sections (the lid and the box base)
Start with one edge of the cardboard roll, and match it to one corner of your lid edge. Glue along the interior seam of the two edges. when you have glued along the length of the curved edge leave 2inches or so to use as a hinge
When you have glued one side, start on the other... you *SHOULD* by now have a domed roof shape
Step 4: Supports
I added some supports to the roof, and to the sides, just because I know my box will during the show inevitably get battered about a bit.
Step 5: Hull
Step 6: Tar N' Feather That Beauty!
It is also now time to glue your lid to your base... you can see what I have done in the pictures below... but using that 2" flap that you left on your lid you can now attach it to the base, if like me and you decide to attach it to the interior, you will need to trim the flap down slightly so that it fits inside... Hold your glued lid in place with some duct tape and leave over night if possible to dry.
Step 7: Batton Down the Hatches !
The banding goes around the top part of the lid, down the back edge... then up the front (not on the base)
Step 8: Swab the Decks!
If you wish paint the inside, I would do it either brown or black... it's your choice.
Step 9: Bootify the Hull!
I also drew a seam where the lid would attach to the base along the back edge.
Using a wide ruler I drew the planking around the sides too... If I had more time or the artistic flair I would have added wood grain
Step 10: Yar Thar Be a Pirate Treasure Chest Me Harties!
But anyway that decision is up to you.
