7 Ohms of Toaster Nichrome

I'm using my 7 ohms of nichrome to limit current to my stepper, since I don't have a chopper yet, and a 12v/20w dichroic globe to load the PSU's 5v line.

Y Bearing
360 Inner

"Y Bearing 360 Inner", although I haven't yet cut the bearing slots in the bottom yet. They'll have to wait for another day.
