I’ve heard the suggestion several times now to use Quantum Hot Sauce fishing reel oil on model and toy trains. I finally decided to try it myself. I like it, for several reasons.
Sometimes a train car breaks, and sometimes you get a good deal on a train car that’s missing its running gear. Whatever the reason, sooner or later most hobbyists find themselves needing to attach trucks to the underside of their train cars, and if they’re like me, they soon find that using a regular nut and bolt doesn’t cut it–the nut works itself loose after a few times around the track, which leads to wobbly running, which leads to derailments.
There’s a solution other than expensive riveting tools, if you’re just interested in making cars run well, rather than restorations that are as historically accurate as possible. For about 15 bucks, you can get enough parts to do 50 cars.
