Introduction: How to Make an Indestructible Money Box
Money boxes are a great way for kids to save money for a special purpose.
Unfortunately we can get tempted to spend the money on other things before we have reached our goal. That's when this money box is useful.
Most money boxes have an opening that allows us to simply take out the money whenever we want. The sad thing about this is that it usually means then box never gets full.
Made from chequer-plate steel, this money box is easy to put coins into, but it's really really hard to make withdrawals.
Please note that you might need to use a grinder or oxy to get the money out, so perhaps it's only for coins, not banknotes.
Step 1: What You Will Need
Steel plate. Whatever you can lay your hands on. It should be light enough to work on, but heavy enough to weld easily.
Measuring and marking gear. Tape and chalk.
Something to cut with. I used an angle grinder.
An angle grinder for grinding.
A welder. I'm lucky enough to have a MIG. It's fantastic.
A hammer also might come in handy.
Step 2: What to Do
- Mark out the shapes you need on the steel.
- Cut the steel.
- Grind the edges so they weld nicely.
- Assemble the cube and tack it together.
- Weld all joints.
- Clean up the welds with a grinder.
- Cut a slot to drop coins through. Position it where coins won't easily come out.
- My steel was a bit rusty so I cleaned it a bit wit a wire brush.
Step 3: Other Possibilities
As you can see I've made a few different shapes.
The smaller cube has been opened twice. You can see where I have patched it.
