I would like to get some non-conductive steam pockets for the front of my shays Frank hasn't had any for quite awhile I don't think he is making them anymore so if anyone out there can make them I

After a brief inspection of the emerald green printed parts (my pictures above) from Frank's source files I've concluded they are of little use except as an experiment. The Anycubic Photon's

RJ: Just tried Sergent Engineering Home Page ... the "Instructions, Etc" button is working, click on it ... then click on the "Click here for Instructions" link ... then click on "3D Models" ... then

Tim: Nice work !!! Thank you for sharing photos, and adding to the knowledge base discussion. Is this HO scale? Please keep us updated on your experiences. Really interested in how the printed

The ABS liquid resins may be strong enough. Stronger if a shaped music wire is inserted partway thru printing. Adding a wire substantially increase the pull strength. The liquid printers have a

RJ, The files can be found under Instructions, Etc then “click here for instructions”. The last one is 3D models. That takes you to the page with the download link. Andrew

I tried to find the source files on the website to no avail. The original instructions didn't work ("Home Page button and then Note from Frank"). Are they .stl files by chance? I just had some more

For those of you who aren’t on the Sergeant Facebook page, Ian Clasper has been doing some really neat work with Frank’s CAD files. Ian drew up a coupled set of dummy couplers for 3D printing that

I will support the effort any way I can because the couplers are outstanding and surpass anything else in HO. Riley Kinney

Here's my first print without any cleanup at all. Some work will be required to remove support remnants before trying to assemble. At this size the parts are quite tough. Don't know yet if they can

To All Sergent Modelers, My name is Alan Hummel and used to talk to Frank Sergent via the old fashioned rotary dial telephone when he was manufacturing the standard E Coupler,in the white metal

Those are some nice looking prints there Tom. From the pictures it looks like there is material missing from inside the ball socket of the top casting, ie, it doesn't look like a plain hole but the

So far, I’ve used 10 Sergent couplers for my fleet of 98 cars. I want to continue using Sergent couplers for a long time. I am willing to help anyway I can to ensure these couplers continue

While hobbyist machines might be resin-only, you can get 3D prints in metal (for instance through Shapeways).

Hi. I've been monitoring this conversation and would like to interject some of my thoughts: my experience with SolidWorks goes back thirteen years; with the addition of a 3D printer about a year ago.

Tim, I'm completely open to anything that helps keep the supply of these great couplers available, and as I noted, it's just an idea. Frank has done a great service to all of us who want a more

Very wise and conservative advise Warren ... I have the very same concern. Once we have enough couplers, I plan on testing in my application. I guess we could do some destructive testing too ...

Before anyone gets too excited over the 3D printed couplers, please note that they need to be assembled and tested under stress of an actual train. It is very possible that due to the mechanical

Tom: I agree with George...the S scale test prints look really great. Mark Lewis

Thanks George ... but I cannot take create for creating these parts, I'm working with some amazingly talented folks that have a common interest. I'm sure Frank, and others who focus on detail, can see
