Batarang From Scrap Metal




Introduction: Batarang From Scrap Metal

About: Student of Geology and Geographic Information Systems who enjoys hardware hacking and creating fun projects for friends, family, and self. Python / C / JAVA

I had some scrap metal sitting around my dorm last spring, so I decided to make a batarang. It didn't turn out as well as I hoped, so I attempted another over the summer! Here they are!

Step 1: Supplies

For this project I used as follows:




Bucket of water

Heat source

Marker/ Pencil


Scrap metal big enough for logo

Step 2: First Go Around

First I started with a piece of scrap metal. The piece used here was to thin and bent easy, so go for a thicker piece.

Trace the Batman logo of your choosing onto the metal, then cut it out. I used a Dremel 4000 and the "Batman Begins" logo.

As seen in my 3rd picture, I attempted to heat up the metal some. I knew this wouldn't really heat treat the metal, but it did give it a nice burnt look to it.

This first attempt is now a magnet on my fridge.

Step 3: Thicker Metal

For my second attempt, I started with a thicker piece of metal; a scrap steel out of an old tv set.

First, print out a template to trace. Then trace on the logo.

I then used a pencil to make rough cut lines.

Step 4: Cut It Out!

After clamping to a base, I used the cutting tip on my dremel to cut out the rough shape.

Then grind it down some with a grinding tip. If you have a bench top grinder, that would be a much better tool to use.

Step 5: Heat Treatment (Kinda)

I had no real way to heat treat the steel, so I just used a ceramic grill to find out what would happen! I don't think it made the steel any stronger, but I did give it a cool pattern.

Step 6: Final Product

Thats it! Try your best not to hurt anyone, but styrofoam dummies make great targets!

    That is so cool! Great instructions, too. It's easy to understand! I feel like if I just had access to a bunch of scrap metal sitting around I would definitely start some neat projects like this. You said you just had the metal sitting around, but where did you get it from?

    I actually cut it out of the side of an old PC case. Take of the plastic coverings and there is a lot of metal in there to use, not the best but its something! Happy DIYing!

    That's a pretty sweet looking Batman batarang. It's really cool how you made that from scrap metal. I'm glad that you posted to use a thicker piece of metal after your experience with using metal that wasn't thick enough. I wouldn't want to make that mistake, so I'll be sure to use metal that's thick enough to make a decent batarang.

    neat project. just an fyi, if you heat the steel to a uniform deep cherry red and keep it there for about 10 to 15 seconds then submerge it into oil you will get a more heat treated hardened part. make sure to sharpen it prior to heating then do touch up again after. water will cause steam and leeching in the steel of its natural oils. oil like hydraulic oil or way oil or any high viscosity oil will actuall help it akneel more and cool faster for a harder finished steel.

    Thanks for the advise! I need a better way to heat it up high enough, but I will definitely try that next time!

    in honesty 2 or three little propane torches would heat it fine
