Introduction: Watermelon Smasher (Post-Apocalyptic Spiked Mace)
Finalist in the
Concrete and Casting Contest
They are coming. Make no mistake about it. The watermelons will rise, and when they do, nothing can stop their insatiable need for human flesh. Guns? Too loud. Blades? Too easy. In the chaos to come, you will need a weapon that can be made with simple household items and requires no maintenance. Behold, the destructive simplicity of the WATERMELON SMASHER!!!
***Cold Steel used to make a battle mace, but it is discontinued. I saw one recently on eBay for over $50. This is my attempt at a homemade version.
Step 1: Safety FIRST
I am dissapointed that I have never really discussed safety in any of my previous instructables.
Protect yourself. I use safety glasses, hearing protection (around power tools) and work gloves at a bare minimum.
Step 2: Gather Materials and Tools
- tin can
- concrete mix
- 1/2" by 1-1/2" bolts, lock washers and nuts (12 each)
- metal pipe
- wooden handle
- spray paint (optional)
- misc screws
- power drill and bits
Step 3: Prepare the Tin Can
- Layout your pattern (I chose three rows of four bolts each...AKA "The Rind Buster")
- Drill some pilot holes (Take care as the tin can is not very strong at this point)
- Drill 1/2" holes
- File off any metal shavings
- Insert bolts and tighten nuts
Step 4: Cut Pipe Sleeve
- Cut pipe sleeve to length (4" above the top of the can, mine is 8-1/2" overall)
- Drill holes in the bottom of the pipe (for anchor screw)
- Insert screw
Step 5: Add Concrete to the Head Assembly
- Mix the concrete (Mix more than you think you need. I chose a drier mix to increase my chances of having stronger concrete after curing. It was the consistency of peanut butter.)
- Insert the pipe sleeve into the tin can. Center the sleeve.
- Add concrete in layers; packing down with pencil.
- Cure concrete (I placed a damp rag over the exposed concrete and put the entire assembly inside a plastic grocery bag. Total cure time was 3 days.)
- Paint assembly (OLIVE DRAB GREEN. It's good enough for a Sherman tank, it's good enough for a watermelon smasher.)
Note: The completed head assembly weighs 5 lbs.
Step 6: Connect Head Assembly to Handle
- Cut handle to length (This is a matter of personal preference; I chose 28" overall.) I repurposed a broken shovel handle.
- Insert the handle into assembly and secure with a lag screw.
Step 7: Smashing Time!
- Stronger alternative then a tin can. Steel pipe or wood block?
- This version is pretty heavy (the head assembly weighs 5 lbs.) I would like to make a shorter, one-handed version that weighs less than 2 lbs.
Thanks for viewing. Fire away with any questions or comments.
