I junked my up and over door and replaced it with a wooden 2 leaf opener, also means you can get wall shelving right up to the door, which was the main reason I did it, the garage wasn't in use as a railway room regrettably.

Another vote for Gaugemaster, dozens fitted on Wibdenshaw with no issues with sound fitted locos.
The only issues I had with the juicers was when using them with NCE CP6 "light bulb" circuit protectors which "blew" faster than the relay operated on the juicer, further experimentation required on that issue!

Bear in mind that the metal used in diecasting is a sort of high melting point solder, I would imagine the only way to get a successful bond would be by heating up the model and using high melting point solder, an Sn10 at around 300 degrees might work.
