I just glued the ABS repair body mounts to the inside of my RS3 shell. Sliding them over the weak Weaver mounts accurately locates them. These must be installed at least 0.1" away from the bottom lip of the shell because the shell slips into a groove in the plastic frame. In the photo below notice that the Weaver mount on the top has already cracked.



New mounting holes need to be drilled into the frame. I haven't used these yet, but I made two different types of marking screws. The idea is to put paint on the head of the screw then slip the shell over the frame far enough for the screw head to make contact. Both of these started out as steel M2 x 6 cap screws.



An initial test fitting of the shell on the frame was successful. The new mounts slipped snugly into cutouts in the weight molds.

That's pad printing. This was used by Weaver, Red Caboose, Intermountain and others back in the day as a way to decorate models with lettering, logos, etc. I watched the process many years ago during a tour of the Intermountain factory in Longmont, CO.

A flat metal printing plate was exposed and etched so that the artwork pattern for a single color was left proud of the field. A machine inked the tops of the letters, then moved a very soft silicone pad over the plate to pick up the ink pattern. The pad then moved over and pressed the ink pattern onto the side of a locomotive shell or car body. The soft pad was able to conform to irregularities in the model surface such as rivets and some ribs.

I want to remove the ink without damaging the underlying paint. So far I've received recommendations for Microsol and Testor's ELO, locally applied.

What printed pads are those Bob?  Can you post a picture?

Hopefully pretty soon. I originally wanted to print the final molds in ABS, but even with supports some of the overhangs are coming out too gnarly to use. Now I'm starting to print what I hope to be final parts in black PLA. Jeff Kraker successfully pours his using thin PLA molds. However, he does the pour with the mold sitting in a bowl of ice water. I do expect the Wood's metal to expand about 1% as it cools, caused by the high bismuth content.

Over the last few days I have found numerous tweaks and improvements to simplify things such as wire management. That seems never ending.

I did print the motor mount in ABS so that it would be more resistant to heat from the motor. Weaver's OEM body mounts are horribly undersized and weak. They crack as soon as the provided self-tapping screws are inserted. I made ABS covers that slip over the OEM features with brass threaded M2 heat stake inserts. These are in ABS so that they can be solvent welded to the styrene locomotive shell.

I'm wondering what to use to remove Weaver's pad printed lettering without destroying the paint below. Any thoughts?

Looks great Bob!!!  Any ideas when the Cerrobend will get poured?

I have an old Weaver RS3 "kit" that needs a Portescap coreless motor so that I can install an HO DCC decoder. There is not room for an ESU 5L decoder, but one of their HO decoders can fit. However, the OEM Pittman motor draws too much current for an HO decoder. What to do? Replace the motor.

This turned into a major 3D printing project. What we see here is a work in progress. A lot more features need to be added to the Fusion 3D model.

The red "bathtub" printed parts are actually molds for Cerrobend weights that replace the OEM weights and increase the weight of the model by about 1/2 pound. No doubt the details will change as I work on the models in Fusion 360.



I also ordered some steel Woodruff key stock from McMaster and that will provide about 2.5 ounces of frame stiffeners to prevent the weak Weaver frame from bowing and cracking.

What prompted this project is a request from the Poobah David to put better sound in his RS3 and also in an unbuilt RS3 kit. This proved a great opportunity for me to re-learn what I forgot in using Fusion 360.

A&O Operations / Guest operators from Tulsa and KC
« Last post by Bob on April 02, 2025, 02:39:39 PM »
On March 31st the A&O hosted a morning + afternoon op session for an entourage of experienced operators from Tulsa and Kansas City. A contingent of A&O regulars also attended as consultants. Special thanks to KT for a fabulous lunch.

Sorry I don't have names for all these faces, but here are the few photos I managed to take during the session. And remember that if you want to see a closeup of any photo thumbnail, just click on it to zoom in.

Jared held down the Dispatchers's desk. I trained him on the peculiarities of the A&O machine and he did a fantastic job.


Here are more grab shots in no particular order.

An empty coal train headed north across the Twin Creek Viaduct. Soon an impromptu photo line of folks stacked up. These locomotives built from P&D kits appeared on the cover of a 2006 issue of Model Railroader. Each currently has a 2" high-bass speaker in an enclosure.

On the distant right the Grand Floridian passenger train would soon pass over the Ohio River on the connecting bridge.


I overheard several comments about the sound coming from the "giant speakers" in A&O locomotives.

The Floridian soon crossed the Ohio River behind two of David's Atlas F3s. These sport Tang Band T1-2025 speaker modules that produce a lot of bass due to their large passive radiators.


A general freight heads from West Virginia to Ohio as it starts across the Ohio River bridge complex behind Alco C425 #475. The dynamic brakes would soon whine to take the train down the ruling grade towards Millport OH.



A loaded coal train just arrived at the Hatfield Coal Company rotary. Here an operator pulls off the caboose and parks it safely on the caboose arrival track.  Soon the loads will be pulled off the tail of the arriving train and shoved across the Whiting Rotaside for emptying. These are all live loads.

The rotary is controlled using the green circled pushbutton visible on the fascia. Once started the dump cycle runs automatically and is synchronized with sound recorded from a real Whiting Rotaside dumper.


Here's the road power, an Alco FA1-FB1-FA1 consist that brought the loads to the rotary arrival track.


Later the B&O ran north on the A&0 mainline to exchange a few cars at International Paper, then it headed into Millport for the midpoint of that turn.



Millport yardmaster Craig herded cats.


What hump?


Heading to the home terminal past the end of CTC.


Operating at the Morrison prep plant. Dirty coal in, clean coal out.


John Parker held down the Ricksburg yard job. Here he answers the Dispatcher on the telephone system.


Ricksburg sorts through car cards to plan his next moves with the Alco S4 yard switcher far left.


An aging Alco RS36 switched the 28 foot long paper mill. That job can take all day! (I've been there and done that job...)

Awesome wife Katie figured out the magic words for putting up the video shorts. Enjoy. More to come.

Greetings-
It has been a long time since I was able to update the A&O website, but that has just been accomplished! Yeah!! I hope to not be so delinquent going forward; we'll see.
There are new categories added and probably an overabundance of data.
If we can figure how to do it, some video shorts will be posted on the Photo page.
Enjoy,
David Stewart
