T-12 Frame-Bearing-Driver Fit Check
Glenn Butcher
I finally got around to reaming the Scalelink hornblocks to 1/8", they were labeled to fit 1/8", but measured out to 3mm. With that, I was able to assemble the laser-cut frame sides, hornblocks, and drivers:
 Surprise, the frame slots all line up and it rolls quite nicely! My laser-cut siderods, however, don't fit, my fault, I measured the middle bearing incorrectly. These are the 13mm drivers, which are oversized based on what I can determine from the drawings I have. I worried that I had to offset the middle driver too far back to keep the distinctive main-rear driver spacing, but that doesn't appear have affected it. There's about .5mm distance between the flanges of the front and main drivers. Next steps will be to order correct siderods and install frame spacers. I'll also install the front and rear bolsters, the frame sides have an extra 0.05" on each end to be bent into tabs to which the bolsters will be soldered. I'm going to spring the drivers with cantilever springs, per http://www.clag.org.uk/41-0rev.html#section8.5. In the same lasercut order I also got my boiler courses, so I'm going to figure out how to roll and solder them. That'll be the acid test of the conelayout-defined tapered course. Messing with the hornblocks, got to wondering: What would be the downside to simply cutting the frame slot a smidge wider than the axle and with a rounded top, and just sliding the axle into that? I have a second set of drivers and axles for a "lessons learned" second build, and that sort of design would eliminate a whole bunch of hornblock hassles...

I've added the files in the Files section at https://groups.io/g/HOn3/files/Uncoupler%20Hanger. I printed them on my Prusa MK3S+ with a 0.40 mm nozzle and a layer height of 0.20 mm (Quality setting) and no supports. I was a little surprised the hook on the hanger came out as well as it did unsupported. Enjoy... Bill Lugg

GUM Uncouplers
I finally tried out these dental tools for uncoupling cars and was quite
impressed with how well they work. However, I was thinking they'd never be where I'd need them, so I printed up the attached little hanger and cap so I could hang several around the layout - along the yard, by sidings, etc. so they'll be handy when I need them. If others would like to use them, I can make the STL files available. Bill Lugg

Thanks John, I never noticed that smoke box before. Cal-Scale also makes a nice working bell with antl-rotation bar. Dale Buxton

HO locomotive detail parts
John Stutz
Recent discussion of sources for locomotive modification and scratch-building parts focused on Precision Scale Models and Keith Wiseman's stock of old PIA and Backshop parts. I will add that Bowser,
https://www.bowser-trains.com/index.html, still offers most of the old Cal-Scale and Cary lines. While these were mostly for the large late steam prototypes of Bowser and Cary, there is much of use to us. In particular, the Cary line includes a 49" smokebox front that is a good match for narrow gauge inside frame 2-8-0s.

Re: Servo v. Tortoises
Alan
For those interested in servo operation for turnouts and other things take a look at the EZYBUS from MERG. I have been using it now for about a year and I really like it. PCB boards are small in size and easy to solder. The little stand alone system is easy to setup and it allows you to make adjustments to each servo. NO DCC required either. Not expensive either! Go to the MERG.uk site and read up on it. Decide for yourself!

I am relieved that I am not the only one finding much of it over my head! But some of the projects and of course their kits are well worth the membership and there's always the hope that a blinding light of understanding will one day home in on me - but I'm not holding my breath!

Re: SJM Co CONOCO Tank Car coupler conversion.
Dusty
When I realized that the 705s weren't going to be a drop in I experimented with the 714 centering device. Like would the 714 box center with a solid coupler rather than a split coupler. I welded a 714 into a solid, one piece coupler. Surprise, surprise it still centers. So the 705 could have been more friendly.
I felt the 705s were more challenging to 'pick' than the 714s but obviously the 705s look better and offer less slack. If my mission were creating images for big time publication I would probably make great efforts to either hide the 714s or build a couple of 'Foreground' prop cars with Sergent couplers and perhaps narrow tread wheels.

and yes, I believe you do have to be a member to order. I've been thoroughly satisfied with everything I've ordered from them. I run MERG boosters off my NCE DCC system and MERG DCOs (electronic circuit breakers). I'm currently assembling a command station (CANCAB) and the other parts necessary to put together a DCC test track I can can interface JMRI to for loco speed matching off the layout. Their forum is extremely helpful - it's like an Open Source community for model railroad electronics. To be honest, most of it is way over my head, but I still reading through the quarterly journals and benefiting from the Tech Bulletins and other resources they offer. Bill Lugg

Re: SJM Co CONOCO Tank Car coupler conversion.
Mark Lewis, I thank you for your answer. It's a hopeful thing, then, to begin a slow conversion. Someday.
I agree with the pair (Marlett and Kasprowicz) about how strange the notion is that it couldn't be made to fit in an existing box. Buxton's notion that a 'hurry up' job is a good and worthy thing mystifies me. Maybe in a real time crisis, but not here. It's a hobby not a war or disaster- we had already waited decades, why not another season or so to find a new die making guy?

Go to eBay, search Model Power 410. There are 100+ at around $25-$27 including postage. The $14 one is the cheaper EST but with high postage.
