FWIW, I ordered a set of the Micromark rollers in January and built this test stand:
Micromark rollers and new test stand
I purchased the O-gauge size and then changed the spacing between the roller frames to resize the gauge for my S-gauge locos. I looked quickly to see what other rollers might be out there before buying the Micromark rollers, based on what others here at OGR have used, but I think Micromark is the only game in town that sells just the rollers and hardware. It seemed like both Bachrus and Crest were no longer around and looking at the Jak website, I could not find a reference or link to rollers from them.
On the issue of the third rail pickup, it's "nothing more" (
) than a piece of 3/16 brass, 1.5 inches long and 19/32" tall (by my digital calipers) -- don't know why it couldn't be 9/16 or even 5/8 -- isn't the third rail roller contact spring loaded? In the meantime, I'm happy to send one of you the one I'm not using - and for double the price, I'll include the plastic spacer that already has the hole drilled in it. Contact me off list.
