DIY Power Resistor

First , hello , I am glad to be here on instructables.com
This is my first instructable.
This is one simple way to create power resistor at home.
I needed 0,33 ohm resistor with some larger wattage so I decide to create one, instead of buying one. I always say, creating is much more fun then buying.

I created small video with these steps
Coating Mass


You will need jointing filler to create mass for coating, to protect resistor wire from oxidation, and to provide heat transfer from wire to environment.
Prepare Wires


You need one old high wattage resistor ( I had one 10W 100 ohm ) to use wire from it.
You will have to destroy it, and take high resisting wire of desired length-resistance. You also need some copper wire as connectors.
Prepare Mold

Also you will need small piece of tin to create mold.
