I have a couple of boxcar doors that are really tight in their movement. The boy, however, insists that these be the cars he wants to put things in. I could try and remove the doors to sand them down a bit, but that always risks a breakage. Alternatively, I’ve been trying to come up with a form of lubricant that is suitable – meaning goes on clear into a small area, doesn’t gunk up over time, and doesn’t risk discoloring or attacking the plastic. Any suggestions or experiences? The best thing I’ve come up with so far is some bar soap…
Soap would be safe it it helps. Grafite comes to mind.
Graphite powder was my first choice - so I tried to find a “clear” graphite (which seems like an oxymoron) and was unsuccessful. One door is green; another orange. Hmmm…
at one time there was a white lube powder it was powder form white lube and it wasn’t that long ago I wonder if that would work I have a little left somewhere but where is the question lol it comes in the white tube just like the actual stuff does.
Maybe some spray Teflon applied with a Q-Tip, liquid wax (like Pledge) or even candle wax rubbed down to a thin coating (?).
Toothpaste works well as an abrasive for polishing plastic. Perhaps you can work some into the doors’ tracks and grind yourself some clearance by exercising the doors back and forth.
