Needed items and tools
18 gal. container:
Hot wire foam cutter
Dremel rotatory cutting tool
Aluminum tray (Buffet tray)
Hot glue gun
Hot glue sticks
Black spray paint
Brown spray paint
Our main item we'll need is a 18 gallon tub here are the dimensions on the one I used if yours measures the same dimensions as on the picture you will have a very similar result from mine using this download template available here.
Prep the tub by cutting the rope handles and the gusset supports around the handles, here I am using a Dremel 200 and a cutting disk. A dremel is a rotatory tool which is very versatile.
I have made these printable .pdf file on the exact profile shape I used to cut the ribs I glued to the tube, click here to download .pdf file.
After you printing the upper and lower templates you will need to tape them or glue them together by aligning the circle indicators. Get a cardboard size that will fit the profile and glue the template to the cardboard (I used sprayed glue, but you could use any glue type) then cut around the edge.
I am using ¾” Styrofoam board to make the ribs for the cauldron, I know sometimes 3/4" is hard to find so using 1" thick foam will work just fine. Place your template on top of the foam board and cut the shape. I am using a foam cutter here, I first tried to cut them by using a knife and it was a more tedious and messy task!
The total ribs I used was 32, in order to have a more or less even space in between them did the following:
- Glued 4 ribs at 90º approx.
- Placed one rib in between the 90º ribs (45º rib)
- And placed 3 more ribs in the generated space.
Complete the rest of the cauldron using the same technique.
Add tape all around and cover all the ribs... I used masking tape because that is what i had available at the time, you might consider duct tape to provide extra strength to yours!
I prepared paper mache paste using 1-part water and 1-part wood glue, percentage of glue might vary depending on how thick the glue you’re using.
I used a disposable aluminum foil buffet tray to put the paper mache paste and to submerge the papers I wrapped on the cauldron. Wrap paper I used is the weekend advertisement type since its soft, newspaper will work just as good.
Once I covered the cauldron I let it dry overnight and here's the result.
Also, here are the links for LED and fog machine with control remote I used inside the cauldron at night time, also included the spooky witch prop with sounds and movement.
