Very bad...

[dknelson]

With some cars the screw that mounts the trucks is virtually creating its own threads in the plastic the first time -- it is easy to jam it and send the screw flying (I have yet to break a frame -- perhaps you should use a smaller screw driver?). If you remove the trucks several times you will begin to notice that there is less and less holding the screw in place each time. Eventually it can just flop out.

You might be able to fix this with standard polystyrene cement, depending on how bad the damage is. I've found the best way to avoid this (and to make installing trucks less fiddly) is to put the screw into the bolster without the truck (to cut a thread) then remove it, fit the truck, and replace the screw. When using self-tapping screws in plastics it's a good idea to back off the screw (think one turn clockwise, then a quarter turn anticlockwise) every so often to allow cut plastic to clear - this helps avoid rounding off the screw head or splitting plastic parts.

I'm not sure I understand what you were doing. Were you installing wheels in the trucks or installing the trucks on the car? If you are working in HO or N you just spread the truck with your thumbs and the wheels drop right in. If you were installing the trucks on the car it seems like you were using way to much force. they should just be snugged up and then the screw backed off about 1/4 to 1/2 turn.
