With apologies to all non-SPF's for hijacking this thread:Thanks for the input, Tony. Really nice looking tender, too. At least one of the PRR switchers used a straight-sided tender from about 1950, so my current plan is to use the short Bachmann Spectrum tender, to save some work. (Attachment Link) Max, you forgot to add that the valve gear needs work, too. That's just too much effort, for too little in return. The layout scenery division has been demanding more attention.
Okay, how about this idea?Use the Bachmann 0-6-0 mechnism, but fit a Trix B6 shell on it, use the Bachmann USRA tender, but use the Trix B6 tender shell on there. That would get you an approximate "Pennsy looking" profile of a B6 on a good mechanism with fine-flanged drivers and nicer valve gear.
Sometimes I think it's not just the material but also a press fit that's too much. Affords all kinds of tolerance on assembly but those that have too much tension finally split over time. And if bad enough, a very short time. Like the time it takes to push it in.

And if bad enough, a very short time. Like the time it takes to push it in. I don't have enough pieces to confirm this as a trend but of the few I have, I have a minimum to maximum difference of around 3/4 of a thousandth (.00075"). When you think about it that's a HUGE difference in these small dimensions. Especially if .0002" gets the job done.
