2-railing Sunset 3-rail driving wheels

What engine is it. I am3 railing a 2 rail Sunset NYC K5. I was going to machine new tires but a wheel swap would be easier.

Pete, it's a UP 4-4-2 ... so I might do better out of a wheel swap!

Without the use of an accurate metal cutting lathe my 2 railing process cannot be accomplished.  If you can find a direct replacement set of 2 rail drivers, I would use them.  Remember to check the axle and crankpin diameters and other dimensions to make sure the new drivers are a good match to your mechanism.

Those Atlantic drivers would not survive Joe's method of cutting the tire to form after pressing.  They might not survive a pressing operation.  If you machine the tires ahead of time for a very light fit, then use shaft Loctite, you might have some success.  The 3-rail tire can probably be sawed off with a jewelers saw.  Cut at the counterweight.  If you need to "skinny up" the driver casting (not recommended) very light cuts on the inner face, then re-gauge by carefully pressing at the hub.

I thought they might have over-done it with the thin-ness of those spokes.  I prefer the Lobaugh 84" driver castings, even though they have half as many spokes as the real thing.

Unless you have a decent lathe, don't mess with it, even then it's nerve racking the first time. That said, it ain't that bad, just have to have a plan, focus, and not skip steps, be methodical cause it only takes one false move to back you up a few steps at the very least.

Unless the 3 rail tires hit the two rail track spikes you shouldn't have to mess with the tires at all. I run brass rc controlled 3 rails on atlas 148 with no problems.

What Ron H sez!!!  I also run BPRC so no wiring on the layout.

Plus...I think even with power to the rails it can still be done as the electronics in my engines are isolated from the wheels anyway.

Those lacy drivers probably look like scata with 3-rail flanges.

Why not look for a trade?  Surely someone wants to go the other way?
