Today, I have a personal favourite: Broadhead Blow Darts!
For this build, you will need:
- A hammer
- A blowtorch
- A metal file
- A jar of oil (I used peanut)
- A hot glue gun
- Large nails (I used screws because they were what I had)
- A vise grip or pliers
- Something hard to use as an anvil (bench vise)
To start, you will need to secure your nail in the vise grips.
Now, turn on the blowtorch, make sure it is not likely to fall, and heat up the nail.
Next, whack hard the nail on the anvil (whatever it may be) until it looks like this:
Use the file to clean up the profile and give the dart an edge.
Now comes the fun part! Heat the nail up as much as you can, then plunge it into the oil. This is called “quenching”, and it makes the metal hard because science! If you have a very hot torch it is possible to make it too hard, in which case you would have to temper it (clean up all the black stuff [scale] then heat it to a light straw colour, then let it cool slowly), but my torch is not very hot, so I don’t have to deal with that.
Take it out, clean it off, and you’re done!
If you want to make blow darts like I have done, go check out this video on Grant Thompson’s channel, “The King of Random” (though if you want my advice and have a few extra dollars, use copper pipe instead of PVC for the blowpipe). If you like my site, you’ll like his.
The darts will look like this when you’re done, and they are not too hard to mass produce and customize.
I hope you liked this project, and I will see you (at least figuratively) in the next post.
