I hope this is the right place for this question. Allright, cheapskate that I am, I bought a number of second hand turnouts, simple, handoperated ones. (Minitrix, with a fairly large box next to it with the mechanism in it) When I tried whether they worked as they should, I found out, that the switch mechanism doesn't seem to work properly as that the direction isn't fully changed. I figured that this could result from two things: either some dirt clogging up the mechanism or a very worn spring which might need to be replaced. If these assumptions sound more or less plausible, then what's the best way to clean one and is replacing a spring doable? On a side note, one of the turnouts arrived in the mail with one rail bent about 90 degrees - can that safely be bent back or will it break or is the item pretty much ruined?
