I see I misunderstood, Steve was advocating body mounting the original couplers, moving the Aristo and Bachmann couplers to the right height.
One thing I don’t get is that in my experience, Aristo couplers on Aristo cars seemed to be at the right height already.
The Bachmann were out of kilter, to be sure, and different Bachmann seemed to have different heights.
But to the crux of my opinion, seems to me removing a truck mounted Bachmann coupler WITH NO DRAFT GEARBOX and then bolting it to a block of styrene will not work as well as a Kadee coupler IN A DRAFT GEARBOX. How do you make the coupler work side to side, and return to center?
It also seems to me that the effort to do either method is about the same, but body mounting the Kadee will guarantee better operation.
Now, if cost and procurement of the Kadees is an issue, sure, don’t spend money and get out the wood screws and go to it. But again I think it’s wasted effort for a poor result.
I’d still get the Kadees and make transition cars shimming the draft gearbox to the right height. How many cars do you need? 1 car for Bachmann and 1 car for Aristo? All you want to do is to allow running different cars. Or do you want multiple transition cars because you have multiple locos?
