I am sorry but I am just not taking many photos of my work in progress. A lot of things I used to do easily I struggle with now and don't even think about a photo until it is too late. I took a few when I started this decoder install but didn't keep at it like I should have. I found time to finish a sound decoder install on a brass BP20 from Alco products. A used ebay purchase. The powered unit had had a NWSL motor installed so it was fairly easy to isolate the motor. I drilled holes under the rear drive shaft and installed the speaker there. I built a platform over the driveshaft so I could put the decoder and current keeper away from the moving parts. I held them in place with UV epoxy and used some of the same to hold the wires away from the shafts. I used a 3mm warm white LED with a 1000 ohm resistor for the headlight. I used the epoxy to hold it in too. The stuff is great because it is hands free in about 10 seconds with the UV light and cures hard in a minute or less.
The rear drive shaft universal to the flywheel was the wrong one but I hat the right one in my spare parts as well as the proper universal joint so I fixed that and gave the gears and bearings oil and grease where needed.
The current keeper just plugs into the decoder and the locomotive will run at least 10 seconds after the power is turned off so it does not have a problem picking up juice.

Charlie,
I am impressed with your skill and your willingness to just dive in.
Those sharks are look great!
