Wrapping up this J2C:
I received the 3d printed smoke unit parts this weekend. Allowing me to get this loco finished up. If you seen the Lionel Dreyfus conversion its pretty similar in design.
With these non Lionel conversions the shell or a major part like a pilot or Cab will have to be the antenna so it has to be insulated from the frame. I was able to 3d print insulator bushings for this project.
On this loco not only did I insulate the shell from the frame, I ended up using the boiler face as the antenna. The boiler face is insulated from the shell too. “Double protection” I found this to be the best option for this loco.
It works perfectly no signal interruptions.
