Hey everyone, in this I'ble we'll be making a custom screwdriver from a plastic fork and a lighter in less than two minutes!
This design works better for tiny screws that are not too tight, and I wouldn't use it to tighten my bike's brakes, but it may well spare you a couple bucks and a trip to the hardware store, and is free and quick to try.
Let's get started!
Step 1: Tools and Materials
You'll need nothing more than :
A lighter or other source of heat/flame (match, stove...)
A piece of plastic : this can be a plastic fork, a toothbrush, a pen... If it melts and hardens again nicely, it'll do the job !
Something to screw or unscrew : I wanted to open my computer's back to remove the dust inside.
Both my lighter and plastic were pink ; although it adds much classiness to the craft, it does not affect the performance of the final product.
Step 2: Heat It Up!
Now, you want to heat the tip of your plastic part without heating the whole thing and without setting it on fire.
I used a bic lighter to heat a broken tooth of the fork as the screw I wanted to remove was very tiny.
Step 3: Make an Imprint of Your Screw
Now, be quick and before the plastic cools and hardens, push it on the screw head, firmly and very very steadily, try to move as little as possible and only exert downward force to fill the screw head with as much plastic as you can.This is why you want to heat up just the tip of the plastic piece, so that you can use the rigid base to push the tip in the screw head with quite some force without squishing all your soon-to-be screwdriver. Then, just let it cool down and pull it out gently. You can blow on it or dip it in water to cool it quicker. Once the plastic is hard again, you can start using it as a screwdriver!
Step 4: Done!
That's it ! You just have to push on the screw and gently screw/unscrew, it should work if the screw isn't too tight. This way, you can make a screwdriver on the go for those proprietary Apple and torx head screws that usually require a specific tool.
