Hello All

Bryian Sones
 

My name is Bryian Sones.

I've been a Modelrailroader for 44 years. I am into Prototype and Fine Scale Modeling. I mainly model the Union Pacific 1958 era in HO and  D&RGW Narrow Gauge, in the mid 50's Hon3. I also have some mid 80's S.P. and Rio Grande and Modern U.P. equipment. I am a Regular Member of the San Diego Model Railroad Club in California. I've been a member of many other various organization some current and in the past, such as, NMRA, UPHS, NMRS, RealSTMFC, RFCB  and WRPM 
I have been using Sergent couplers on all of my equipment for about 6 years. I am interested in the group to learn more and share knowledge.


Kind Regards,

Bryian Sones

Does anyone happen to have any extra long shank lower shelf, double shelf or type Fs they could spare?? 

Couplers for sale

William Gossett <gossport43@...>
 

I have a number of mostly pre-assembled EC87 couplers for sale.  19 EN87A have coupler boxes pre-installed and 28 EC97Ahave no coupler boxes.  Also a few un-assembled sets, an uncoupler tool and a set of BCL87 etched linkage.  Please message me for list and pricing if interested.  Wish to sell as a package.

Hi Will,

I'd be interested...and shipping ought to be cheap.  Please let me know what you've got, and what you want for them.

Thanks,
Jeff Scarbrough

Hi All,

Anyone have a few of these couplers that would be willing to sell me please?

Thank You!

3D printed top/upper shelves, coupler boxes

Ryan Harris
 

I just received a successful test print of some parts I designed to fit the HO scale SBE coupler. Since the SBE coupler is diecast it doesn't suffer from the availability problem that the SE coupler does. Those of us modeling tank cars need the double shelf couplers, so when they became unavailable it was cause for concern to me.

The solution I came up with uses the original CAD files Frank made available, and with Tom Colasurdo's gracious help converting them to a format I can use, I created parts that can be attached to the top of the coupler. The result is SBE couplers are converted into SE couplers.

Here is the link to the parts on Shapeways if anyone is interested:

http://shpws.me/RuGO

I am also working on some draft gear boxes for Sergent couplers and I've successfully prototyped those, however I have not printed the latest revisions. If that's something that sounds interesting you might want to hold off a few weeks until I get the latest samples tested. Here are the Type E draft gear boxes installed on an old MDC Roundhouse flatcar:



The Type F boxes function the same but assemble slightly different and have the distinctive Type F striker plate. Both draft gear boxes allow the coupler to pitch up and down and to twist somewhat within the box, alleviating some of the stiffness cars may experience over less-than-perfect track, especially cars with tightlock and shelf couplers.

That is awesome, how well to they function with the other couplers? Also have you put into any thoughts of doing the type Fs? While I have many tank cars that need the double shelfs I also have an entire coal train that needs the type F couplers. I've been looking all over with no luck finding any.

Ryan, that's fantastic work, as always! I really like what you've done with the draft gear. Nick Molo's parts have been a huge help to mean in getting closer to the realism that I strive for in my models, but these sorts of parts that are tailored for Sergent couplers are another great option. I've been meaning to order some of your Type E coupler boxes and will do so shortly. Most of my CSX diesel and freight car modeling subjects seem to use lower shelf Type Es - it's like they did a big conversion in the mid-'90s from standard Es to lower shelf.  There is this one oddball - not sure why they put double shelf couplers on a 50' box car:

CSXT 502490:

I need to get on the ball and order a 144-pack of SBE couplers.  Thanks for the update on your projects, Ryan.  Do you mind if I share this on the Sergent Facebook page?  I'm not sure if you're a member on there...

Todd, if you're not on Facebook, Ian Clasper has been doing some really interesting things with 3D printing based on Sergent's designs.  He has created plastic drawbar versions of Type F coupler, which represents two Type Fs coupled together.  One has a solid shank that fits over the usual mounting pin in the coupler pocket, while the other has an open end that clips into the pocket on the next car.  He's tested them, and they seem to hold up well.   He did the same thing with the standard Type E design.  I'm attaching two photos.  Ian has a Shapeways store, but he's only selling the couplers directly right now (I think he's using a different 3D printing service for them, or maybe his own printer).  I think they're a great economical alternative to buying and assembling a unit train's worth of real Sergents.  When I get around to it (unit coal cars aren't a priority for me right now), I'd like to use his drawbars to make sets of maybe 6 or 10 cars, with real Sergents on each end.

David I am on the Facebook group and have seen Ian's work and it is great work. However I am looking for operating couplers due to the scope of my operations on the model railroad.

Thanks, Todd. The shelf doesn't affect the operation of the coupler at all, other than limiting the ability of connected cars to separate. The uncoupling function still works as intended with one of the Sergent uncoupling wands. The coupling function is unaffected by the shelf as well.

I don't think using Shapeways to print in acrylic would result in very durable couplers, so I haven't attempted to print any operating couplers. Ian's part that Dave posted below looks like a good solution for F couplers. I would prefer dummy couplers that look like F couplers but can be separated. The trouble with that is that the couplers interlock, so the design would have to be modified to allow the couplers to slide past each other.

I can only imagine the time is coming when the wax printing problem is solved without Frank chasing down an expensive rabbit hole and the couplers are available once more. I have enough F couplers for locomotives but not many cars. Like you I have coal hoppers and gondolas in need of proper couplers.

Feel free to share all you want, Dave. I'm not on Facebook so this group is the only place I've posted anything.

I've seen SE couplers on several cars they "shouldn't" be installed on, including boxcars and reefers. They are becoming more and more common on pellet hoppers, too. And SBE couplers have been installed on many cars. 

I am going to buy a big pack of the SBE couplers soon. I still have quite a few tank cars that need proper couplers. For now I have a couple dozen of the SBE that I got in small packs to convert.

I like Ian's idea for unit trains. They look very good. I have an idea for making rotary couplers using a variation of the Type F box I designed, but I am not very adept at manipulating Frank's CAD files.

Ryan I certainly hope you're right about the Fs coming back into production. Frank really hasn't said anything in regards and i feel like he's just expecting someone else to take over so he doesn't have to keep trying to find a fix. I've got many many couplers I'm in need of that aren't in stock. Long shanks, doubles, and type Fs

Ryan: What do you need to “manipulate” Franks CAD files, or perhaps better asked, what kind of manipulating are you looking for? I’d be glad to try to help you if you want me to.... no strings.... just available (retired) with extensive SolidWorks and STL experience.

Hi Tim. My old version of AutoCAD can't do much with the files as is, but I was able to redraw the upper shelf using Frank's CAD file as a model. The Type F is a much bigger undertaking for me since I'd have to redraw it entirely.

Essentially what I'd like to do is attach the knuckle to the coupler body in the closed position, then modifiy the coupler to eliminate any interference between coupled pairs. I'd do this by moving the knuckle slightly outward from the coupler body (away from the shank). Then I'd move the female portion of the interlocking tab backward toward the shank so the male and female tabs on coupled pairs do not interlock. Finally, I'd remove any interference of the lower shelf between a coupled pair. The idea is that the couplers would look like Type F couplers, but they would be dummy couplers that can slide apart vertically. Then I'd make compatible shank and rotary shank versions.
