So, I got some vintage train transformers, all are putting out 18V or more. I wired my frames and then tried to use them to embed the wire.

No luck. The wire doesnt even get warm. I left them clipped on there for 5 minutes. No dice. How are you guys using train transformers to embed wire? There is current passing through the wire, but its not enough to warm it up. Ended up just using a spur embedder for the first one.

Kind of disappointed because I read that these would work.
