Hi guys I am going to show you to make your own metal ninja star
Step 1: What you will need
What you will need:
1. A piece of metal about 3mm thick and 6cm x 6cm (2.3 x 2.3 inches) wide ( you can vary from these measurements to make it the size you want.)
2. A hack saw
4. A ruler
5. A pencil
6. A vice
7. A drill press/hand drill and drill bits
Step 2: Marking out the star
Draw a line vertically a horizontally so that the lines meet exactly on the centre. One center meter (0.4 inch) down each end of each line make a mark and then draw a line from the mark to the corner for each one. And drill 5mm (or near enough) holes where the arrows are pointing on the picture (make sure you get rid of the burs).
Step 3: Start cutting
Cut the metal between the corner and the mark you made do this with all the of them.
Step 4: Grinding time
Grind the stars so that they it sharp. (You can use a file if you don`t have a bench grinder. But i`m lazy )
Step 5: Your done
Your done test it out but be careful with your new ninja star and don`t use it inside I have seen these go through the wall have fun but be safe.
