Step 3: Transfer Your Outline

The hardest part of this project is getting the outline onto the saw blade. We tried a bunch of different methods: Spray paint, Sharpie, lightly scoring the outline with the cut-off wheel, and gluing the profile onto the saw.

Spraypaint worked great for the initial outlining and gluing the profile on worked really well towards the end. Whatever method you choose, make sure you have a method for removing the marks after (acetone or grinding for the paint and sharpie). For the most part, we didn't have to do a lot of cleanup as we stayed pretty close to the lines. The heat of the grinder made the adhesive on the paper pop off fairly easily as well.

<p>Great Instructable! Love<br>the nod to safety. A few years ago I myself cut out some different<br>batarangs using similar techniques, which you can see from the photo<br>I posted. The Dark Knight trilogy is my favorite Batman series.</p>
<p>Those look great! The curves are not easy to do!</p>
<p>Yes...</p>
<p>Nice work. Can you actually throw them?</p><p>I voted</p>
Yes! We've thrown them a bunch.
<p>Of course! They are just like shurikens.</p>

You took the words right out of my mouth.
<p>I always vote for Batman stuff! Great build!</p>
<p>Epic build my friend..!!<br>You just got my vote :) </p>
<p>Thank you! Your Batman wall is fantastic.</p>
<p>Thanks for the tutorial! I made these with my son. I got some 24&quot; sawblades that worked great.</p>
<p>Go big or go home, right?! Those are super impressive, enough for a bat cave.</p>
