This is an egg on the construction of ninja stars or shuriken.I know im gonna get a couple of
\"Old 1*\’s and stuff like that but these arent spot welded
or made of cds. These are made of solid steel. This requires expensive machinery that
most average joes dont have in their garage. However if you do have the neccesary equiptment
this can be a wonderful moneymaker at school.

You will need:
A 2 1/2\"-2 1/2\" 1/8\" thick square of steel
Plasma cutter
Bench Grinder
High rpm drill press (optional)
Burr whip(optional)
Spray Paint, any color(optional)
Sand Blaster(optional)
Shuriken design (attached or use your own)
Marking pen

1.Draw an outline of the star on the 2 1/2\"-2 1/2\" sheet of steel.

2.Carefully cut the outline of the star out using the plasma cutter.

3.(Optional) Use the drill press to drill a hole, with a one inch twist bit, in the middle
of the star.Using the burr whip remove the burrs inside the hole left from the drill bit.

4.Grind off all of the burrs and excess using the bench grinder.

5.Sand blast the star with semi-fine sand to give it a nice finish.

6.Using the bench grinder sharpen the points and inside edges of the shuriken.

7.(Optional)Spray paint the star.If you want you can grin the inside edges again
to give it a shiny finish.


And there you go. An easy ninja star that can be mass produced and sold for about 5-10 dollars
each.

Have Fun!
