Hey Dude

Why not simply use a Vitreous Enamel power resistor such as this one

It is commonly used in the Reprap heater block design pioneered by Nophead.

Much cleaner and you don't need the cement, nichrome wire etc.

I would have but the time did not allow for shipping. I bought one of the first MK6+ upgrade kits and the heater core broke in the first 15 seconds and I needed the printer the next day for a presentation so I made one with what I had.
