Introduction: Hard Drive Platter Throwing Star

Picture of Hard Drive Platter Throwing Star

This is how to make a throwing star from a hard drive platter. With this design I have gotten penetration of about a half an inch in a piece of card board with practice.

Caution : These are not toys, you could severely injure yourself as well as others. i assume no responsibility for what you do with these.

Step 1: Gather Materials

Permanent Marker
Scissors (Don't Use Your Best Pair They Dull Quickly)
Hard Drive Platters (One Per Star You Plan To Make)

Step 2: Draw Lines

Layout the line by using the pictures.
1) draw line across the cd at about the half way point. to make a plus sign.
2) measure up any where from one eigth inch to one half inch from the middle of the circle along the lines drawn in step 1.
3) working line by line draw in the lines from the edge of the outer edge of the lines drawn in step one, to the marks made in step 2.

Step 3: Your Done

Then Cut Around The The Out side lines to get a star shape.

Then your Done, now go throw your star at some targets!

Aren't HD platters kinda fragile?

DeriemD (author)trumpkin2008-03-23

not if you use the older hdd's (like 1gb's)

Some older laptop hard drive platters are made of glass or ceramic.

DeriemD (author)pighair472008-03-23

yhea laptops are generally thinner than pc's the one i work with is at least 1 whole mm

pighair47 (author)mikalelynch2009-05-29

Since when do scissors cut through HDD platters? How thick were they?

that was the first thing i thought when i read this... my second thought, im using a dremel and a knife sharpener!

globe (author)2008-11-29

can't you just CDs? or is that what that is?

pighair47 (author)bigfootduck2008-06-16

you can but they usually shatter on impact, i used hard drive platters out of a hard drive.

Please do tell how you managed to cut through a hard drive platter with scissors. I used heavy duty nail cutters and they just put a large scratch into my platters. Hacksaw is the best to use imo. Unlike scissors, the saw won't warp the disc when you cut it. FYI my platters are from a 20gb HD made about 3-4 years ago. You may also want to consider designs that use more then 4 points. Six or more would lead to better impact results and look nicer in the end. Also using an angle grinder to sharpen the edges will help.

What's does this have to do with thanksgiving leftovers?

pighair47 (author)2007-11-30

it depends on the plater as i later found out some are thicker than others. it pretty light and flies pretty straight.

zieak (author)2007-11-27

Scissors can cut though hard drive platters? Impressive! I might try this with some tin snips though - maybe even file the edges. Is it really light? Does it drift when thrown or can you keep it going in a relatively straight path?
