So, continuing on with the decoder install, I needed to drill and tap the hole for a 2-56 screw. Since I am using the main drivers for a pick up I will attach one leg of a Microtronics 3 pin micro mini connector to the new screw. The other 2 leads will be soldered on the posts on the NWSL motor. Incidentally, I used a NWSL 2032D-9 motor, 2.0mm shaft with 9500 RPM's. Gearbox was also from NWSL part# 153-6, which was recommended for Bowser freight steam locomotives.
Hole will be drilled where black dot is at.
Hole is drilled and tapped.
With screw for pick up wire.
Here are the connectors I use. 3 pin for motor leads and pick up. 2 pin connector is for the headlight.
Before, I put this on the test track. I checked the mechanism for any binding, which I found of course. I needed to tighten up some screws in the valve rods I had left loose. Added a touch of CA to the threads to prevent them from backing out. Here is the drive being tested with a transformer after the binding was taken out.
Next, I solder in the 3 pin connector leads.
I was able to put the whole thing back together and for the first time in about 4 or 5 years the darn thing ran down my test track. I was trying to post a video but it won't upload to my Photobucket page. Not sure if I can post a video here also. Anyway, the H-9 topped out at scale speed of 48 mph. Since, I do not have anything to reference that number to I'm going to assume that speed is relatively accurate. If anyone has an info that they could share I would certainly appreciate that.
