Large Scale Central

Building a Track Powered Crossing

This conductivity was over a very small area, perhaps a small chunk of steel was what happened.

This was some ditch lights in Z scale, using surface mount LEDs, and JB Weld was used to glue them to the deck on a Z scale loco. The LEDs no longer lit, and there was a short and the current melted the JB Weld… so maybe over short distances it can conduct…

LMAO…the thought of Z scale ditch lights are just plain sick!

friggin tiny, can tell you!

How do you keep the epoxy from sticking to the styrene strips?

Certain types of plastic, like LGB ties and butter dishes have a greasy enough surface that it is very difficult to get epoxy style glues to stick. If you had a broken LGB or similar railroad tie and you wanted to keep it together, I'd put a small self tapping screw into each half of the broken tie and then on the underneath side fill the area around both ties with epoxy. It would be a strong fix.

We use the same stir sticks and mixing dishes over many times by just waiting until the epoxy kicks and then breaking out or off the hardened epoxy. If you want it to come out faster, spray a little “Pam” or “Pledge” into the mixing dish before mixing the epoxy. We spray it in, then wipe it out, so it is just on the surface and doesn’t mix in with the epoxy resin and hardener. You could also wax the inside of the container, or any surface you don’t want it to stick to, with mold release wax or car wax.

Very interesting . . :slight_smile:

With some personal set backs I did get this finished.

Nice work

Very nice.

Not only did he finish it, but it arrived on my doorstep this morning! Thanks Rodney, it really looks great and I look forward to using it.
