(I will not go into how you should mount the feathers themselves, since I don't have the know-how to do it correctly. I just moun them straight and with 120 degree spacing. It works for me.)
This is how I built my own feather-cutter that gets consistent results, every time.
You will need:
- A fused bench power-supply. A standard one that can output 0-40V should be plenty.
- A few scraps of wood.
- Two long bolts and four nuts and two wing-nuts (I've used six nuts as I didn't have any wing-nuts then).
- Wire (I used 0.8mm Stainless Steel Welding wire)
- Flat-nosed pliers.
- A drill/electric screwdriver.
- Wood-screws suitable for your wooden scraps.
- Cables and alligator-clips for your power-supply.
I am in no way responsible for you getting electrocuted, burned, cut, etc. while following this instructable.
