The problem is that all motors this size have thin PM brushes. You could potentially open one up and glue small rectangular carbon brushes to the precious metal ones, but that's pretty finicky work and may not hold.
This may help some of you guys, may not, but I overhaul these with factory parts I've hoarded. I have also experimented with improving some things to reduce the strain on the factory motor. A: Get newer magnets if you can, ceramic maybe? B: Some armatures work better than others, you may have to swap out a few to find the best of what you have. C: The later the PT motor is better at dissipating heat buildup...with the tender drive, you are limited by the block style, of course. D: Install the diesel axles instead of the 4-traction tire wheels, here's why: The plastic non-geared traction wheels almost always are cracked, hard to find good ones, and are overkill. The diesels always ran better to begin with, even better were the 3-axle motors. With a solid axle, one wheel or the other needs to slide on a curve, or you will get strain and binding of the drive, there is such a thing as "too much" traction. These will also double your electrical pickup in the tender and reduce the jerky stalling whenever the lead and trailing bogies get dirty or cross dead spots. With the plastic-frame tender-drive, open up the center slots in the frame, and add a 3rd axle! With 3 traction tires and 5 pickup wheels, the thing becomes more reliable, like the GG-1 and the E7. E: Put some weight in the Tender Shell, it needs weight, especially with the plastic-frame versions! F: Get rid of the "smoke puffer" stick hanging down under the loco boiler. It jams the front drivers frequently. The smoker works fine without it. G: Add a second powered tender, I've done it and it looks pretty impressive. Use a spare rear talgo-coupler frame on the front tender bogie to couple it to the 1st tender, add a 2-wire micro connector between the 2 tenders, and double your power, viola! Graves

We all agree on the magnet upgrade, and I have noted that some armatures do perform better in my experience. I've gone through a lot of 'torques, and I've found that a stock, strong running motor is hard to beat, but a weak running PT seems to be difficult to conquer. We've got ten PT equipped locos on the BC, and all of them run pretty well, but do vary in performance.
I was wondering if you would be able to use ho slot car brushes instead of the brushes that came with the original PT motors? Thanks.
They would work as long as they fit the brush holder bores properly and were similar in thickness to the originals. Note that Life-Like and Bachmann pancake motor brushes and springs are a direct replacement on Powertorques.
rbturner: Many years ago I built a Budweiser Clydesdale, 8 horse hit w/ wagon. It sat on a cobblestone base. I painted each cobblestone individually with various earth tone colors. It looked great but was a real job.

frankenstein: Why get stalled? Things like that have a great variation to them, and are largely interpretive.

ZeldaTheSwordsman: Because I needed to be sure the cobblestones weren't completely off the wall before proceeding to the weathering stage of painting the base. I know there's a lot of variation, but I was worried I had still managed to goof it up

methuener: My B&O Pratt Street layout will be all street running and all cobblestones. I'm going with paper sheets with cobblestones printed from photo images.

eilif: Is there a topic where we share our collection of rolling stock from other member's freelanced railroads? I've got a BC&E on the way that will join equipment from JNXT, NMN, and JFI, it'd be nice to have a specific place to share this stuff.
Aug 12, 2019 8:29:48 GMT -5
JNXT 7707: I don't think there is one, or a specific place for that - but just create one under "Gone to Beans Coffee Shop" I'd say. Sounds like it could be fun!

JNXT 7707: I've also acquired a small handful of mystery freelance roads from train shows, done with such care that I can't think of stripping them.

John: JNXT, Don't want the cars but would like to see the pictures. Please!

John: I guess I will never understand the romantic nostalgia that is felt about Woodstock. I grew up in that era. Woodstock seemed more like a Drunken Roman Orgy than a music festival. I guess I was a Red Neck then too.

rbturner: John; AMEN.
Aug 16, 2019 12:06:03 GMT -5
JNXT 7707: I second that. I do like some of the music but the event itself was a disaster. It has improved over the years though, like a fine hippie wine

pokemonprime: "seemed more like a Drunken Roman Orgy" yep I think that's why some people went.
