Easy Halloween Casket Fog Machine Cover




Introduction: Easy Halloween Casket Fog Machine Cover

I have had a fog machine in my Halloween decor for a couple years now and each year I try to find ways to hide it and protect it from the weather. 
This year I came up with this casket. 
The cost is cheap.  I used materials I already had on hand. but if you dont have wood on hand your lumber store will have a scrap section!!
This instructable is for a smaller fog machine, however you can make it bigger if needed.  but keep in mind your fog machine needs room to breath! 
Do not allow the machine to touch any part of the wood so measure for enough space. 
My fog machine is 9" x 5" x 5" if yours is the same continue on with these instructions. if it's bigger add as many inches to each measurement as your machine is bigger in inches than this one.
This casket can also be made for decoration only.  I will note which steps to skip if you are making it for decor only.


plywood I used 1/8 inch thick
furring strips about 5 1/2 feet total
wood glue
black spray paint
black hose that will fit over the end of the part the fog comes out of ( you can purchase an attachment for you specific machine I used a store bought set that splits in 3 and has headstones on the end of the hoses where the fog comes out)
optional: gray paint, caulk and thompson's water seal


circular saw
jig saw
yard stick
tape measure
staple gun
drill and 1" hole cutter

Step 1: Measurements for Drawing the Casket

On the plywood start at the corner measure 16" in from the end.  Make marks at 4", 8", 12" and 16".

Measure 24" down the side and measure and mark 4,8,12, and 16 inches as shown in picture.

Step 2: Drawing the Casket

Using your yard stick you are going to mark your lines for cutting the casket top. 
Start by drawing a line from the 4" mark to the 12" mark on both the top and the bottom.
Next draw a line from the top 4" down to the end of the board, this is approx. a 25 degree angle to make sure it is correct the line will measure 7".
Draw the line from the 12" mark but stop at the 16" inch line. It will be a 7" line just as the other side.
Draw lines from the ends of the angle down to the 4" mark from the left and 12" from the right.

See photo for details (sorry for the bad drawing)

Step 3: Top of the Casket

The drawing shows what your measurements should be.  Measure twice. 

then using your circular saw cut out the casket top.

Step 4: Cutting the Sides

measure and cut:
two 7" x 9" pieces
two 8" x 9" pieces
two 19" x 9" pieces

Step 5: Hose, and Cord Holes


Using your jig saw cut a "mouse hole" in the bottom of the two 8" x 9" side pieces.  Making sure it is high enough for your hose to protrude from. You may want to stand it up over the hose to be sure it is cut high enough.

Step 6: Vent Holes

Using your drill and 1" hole cutter  drill 4 to 6 vent holes on each of the 19" sides and 1 or 2 on the 7" sides.

Step 7: Cutting the Furring Strips

Using your circular saw cut the furring strips in 12 pieces

for the casket sides you will cut six 5" pieces

for the top you will cut four 4" pieces and two 9" pieces

You can make the strips longer if you like.  I used materials I had laying around.

Step 8: Attaching the Furring Strips to the Top

Put a bead of glue along the length of  your tow 9" pieces.
Position centered on the 19" sides right on the edge and carefully fasten with staples.

repeat for the four 4" pieces.

see photo for details.

Step 9: Attaching the Sides

put a bead of glue along the side of the top 4" furring strip
position one of the 8" x 9" pieces to the side being sure it lines up staple in place
do the same thing for the angles using the two 7" x 9" pieces

the photo is a top view, the blue lines are the side pieces.

Repeat again for the 19" pieces and the final 8" piece.

Step 10: Side Furring Strips

Now you should have your sides stapled on.

using the 5" furring strips glue and staple each one on each corner inside the casket.

be sure your sides are tight.  There will be small cracks.

Note the ends will not be perfect.  If you like perfection this is the step where you will be using that optional caulk.  use the caulk to fill the cracks and the raw edges on the outside.  Your cracks should not be gaping... if they are you may have measured wrong.

Allow the glue and caulk (if used) to dry.

Step 11: Painting

We applied Thompson's water seal to the bare wood inside and out in this step.  You do not have to use it. If you do, allow it to dry before continuing.

Paint the entire outside of the casket with black spray paint.

allow it to dry


I used gray outdoor paint to paint a cross and a decorative border around the top of the casket.  You can also add R.I.P. or a creepy saying.

Step 12: Finishing Up

Now for the finishing touches.  You can spray the casket with a clear coat. I used poly. This is not necessary but it will help your finish last longer.

put the hose on the fog machine decide where you want it placed and then put the casket over it fitting the hose and the cord in the "mouse holes"

NOTE: you want the hose long enough so that the fog does not release inside the casket... that is unless you want a fogging casket ;)

Thanks for reading my first instructable :) please share your caskets with me!!
