I have an older N scale Life Like Amtrak F40PH that I am trying to turn into a dummy but instead, I think I'm the dummy as I am having problems with the coupler conversion. (Bear with my lingo here as it seems the names I have for the couplers is different from what everybody seems to be using now!) The Life Like has Rapido couplers and I am trying to change it over to Micro Trains Kadee's. I am using the 1128 MT-7 couplers with adapters kit and have spent darn near all day arguing with the adapter, spring and top and bottom halves of the coupler. I finally gave up and decided it was not going to happen and combined the two (old parts and new parts). I used the spring from the Rapido (as it was bigger and stronger) and the original box cover (the little plastic piece that holds it all in), and then the flange and coupler from the Micro Train kit. While I was at least able to get this bunch of stuff assembled, my coupler does not have the holding strength to pull but maybe five or six cars before it just decides to drop down and "turn loose." Any ideas? This should have taken 10 minutes, not all day. Maybe I can just whack off the original plastic stuff sticking out from the truck and try and figure out how to attach some shell mounted couplers instead?
