Nicely done. The shooting angles give you a clear view of what is occurring. The video is clear and in focus with great definition. The audio is clear and level. Bruce did a great job developing the content for the video and presented it extremely well.

With segment 2 "Alternative Player" I get access denied. "Play Video" is ok but I need to use the "Alternative Player"

Had an access setting wrong - try it now.

OK now


Excellent  video, now I have to screw up,the courage to do the same thing in N scale. Thanks , John T

Outstanding video!

Wow, is the information professional, everything was shown and explained.
Thank you very much I love these videos tremendously.


As usual very good install. Question; in lew of an ultra sonic cleaner soak the parts in the cleaning solution for a couple of days?

Bruce says:

Soaking and brushing will work over time. The ultrasonic gets things done in minutes and the ultrasonic cleaner can be had for less than $20 these days.

Here's one on Amazon (free shipping if you're a prime member) for $12:

Cool! Thanks Bruce, thats affordable even for a larger one as I'm in O scale. I orignaly lookd at the Foredom ultra sonic cleaners, very salty.
