    Question Roundhouse rollling stock - MT trucks & couplers

    I'm in the process of converting some Roundhouse rolling stock to Micro-Trains trucks & couplers. I have found that on the plastic underframe cars (kit or prebuilt) I have to add 2 MT washers to take out some of the slop. Even with 2 washers the trucks are still sloppy. On the metal underframe cars - all I have to do is switch to the MT bolster pins and that seems
    to work fine with no extra play. I tried using the MT bolster pins on the plastic underframe cars, but that didn't seem to help. Short of using 3 or more washers, does someone make thicker flat washers that would fit in this situation? Plastic or metal would be fine. If so, what would the exact dimensions of said washers be? p.s. I'm too lazy to convert to body mount couplers.

    I have never had a car where I had to add more than one washer, and that was to adjust ride height. I think you should try another means of attaching the trucks if you are needing 3 washers. Maybe you should get some screws.

    I agree with @jpwisc a screw fitting would be better if you have so much play in those trucks. I picked up a 'retro fit' set a while ago. It had a 2-56 drill bit and tap in either end of a double pin vice and a packet of machine screwsto suit. Have a look on ebay or some hobby tool supply place for something similar.
