Newman motor #2 by detrix42

Ok, I will do my best to document the construction of my next commutator including pictures.  I missed a couple of opportunities to take some picture at the very beginning, but I am not to far into, just like 3 steps into it.  Pictures speak better than words...

I've found placing a suitable capacitor across the leads of the ammeter will provide more accurate results.

My second Newman motor has been completely disassembled, to make room for motor #3.  I will continued to post my progress of building motor #3 in this thread, but when I am finished (which may be a while), I will start a new thread.

But motor #2 is now no longer available.

Hello everyone.  Here is a small update, so you all know that I am hard at work building my next motor.  Below are some pics of me building a really big commutator out of a child's bicycle wheel rim. 

Pic #1: my setup for soldering the wires to the copper segments.
Pic #2: my soldering skills 
Pic #3: 20 segments ready to go on the commutator

More pics of my commutator being built.

Pic #4: Putting copper segments on wheel.  Using a spacer piece for exact placement
Pic #5: Showing spacer piece removed.
Pic #6: Done puttting copper segments on.  Worked out exactly as planned with the spacer piece.

I will be adding short-out segments tomorrow, plus other stuff.
