Subject: Cleasning Castings Before Assembly

During cleaning up the castings before assembly, has anyone ever actually broken off the little piece on the knuckle that the ball locks against when the couplers are locked closed?  This piece is the area in red in the attached photo.  I have recently acquired a few micro-sized wire brushes that I'm considering using to clean up the parts prior to assembly, and I'm wondering how careful I should be with these brushes in this extension of the knuckle... or if I should use the brushes at all?

(I ask this about both the HO and S scale couplers, assuming the S coupler to be more durable due to the larger size)

I've only broken the tang off once from memory, and that was one of the
original hand cast couplers. I have filed a bit too much off the end
of the tang on the diecast knuckles before but not broken it.

My usual way to clean the tang is to either just use a hobby knife and
give each side a quick scrape or if really needed a couple of quick
passes with a needle file.

I assume you're referring to the HO couplers?  I wonder if the same is true for the S scale coupler?  Either way... good to know.

By the way... how do you remove this flash?  Nippers?  File?  Something else?

You shouldn't have any issues. There is, however, sometimes a little piece of flash that you need to nip off on that horn.

I haven't broken that portion off, but I have a few where I've broken the shank at the hole where the bottom plate attaches. Each time it was during assembly as I pressed the parts together. All three were different styles, too.

The part you have to watch out for is on the very end of the red highlighted part and I don't find it on every knuckle, only one in three or four. Dry fit the knuckle and bottom plate without the ball to make everything works, then assemble the coupler with the ball. If it doesn't work it's pretty easy to find the cause and correct it before final assembly.

Very little cleanup is required. For me I make sure the cavity for the ball is clear as well as the cavities for the nubs on the knuckle. I also make sure the knuckle face is smooth. If those points are good, I dry fit the parts.

I’ve been removing the flash with an X-Acto knife or scalpel, and fishing any walnut pieces out with a straight dental pick. I haven’t broken anything yet, but I’ve only done about 20 of them (all Sharons).

Announcing new coupler gauges for HO standard gauge and narrow gauge models

Mike Conder
 

Pardon the multiple posts, but I'll only post this announcement once.
 
My company, CESCO, has completed and tested designs for a group of coupler gauges for HO stnadard gauge and several  narrow gauge models.  These are 3D printed plastic gauges, so they can be used on live track without shorting out the track.  CESCO has them available for HOn3, Sn3, On3 and HO/On30 installations.
 
The gauges use a design and dimensions taken (with permission) from an article by Jim Vail in the Sept/Oct 1988 issue of the "Narrow Gauge & Shortline Gazette."  Jim also has just published a review of the gauges in the Nov/Dec 2016 issue of the same magazine.
 
CESCO is currently using Shapeways for printing these, and they are available from Wolf Designs at $12/each for the  HOn3, Sn3, and HO/On30 gauges, and $15/each for the On3 coupler (due to its larger size).  CESCO is also working to get them carries by a couple of other vendors.
 
The gauges are also available directly Shapeways as well.  Since these are new products, the gauges have a special introductory price of $9/each for the  HOn3, Sn3, and HO/On30 gauges, and $12/each for the On3 coupler.
 
Direct links to the Shapeways store are as follows:

So the standard coupler height for HO equipment and On30 equipment is the same? I guess I would have expected On30 equipment to stand a little taller.

I ordered one in HO-On30 and HOn3 just the same; I love the simplicity and the fact that you can get them in a bright color so I can find them when I need them.

Thanks.

There's something about that that had always bothered me, I personally think that On3 and On30 should use the same height, since most On30 is lazy On3. All this Colorado outline equipment built on a compromise track gauge, but this is not to say that cool stuff can't be done with it.

Re: [SergentEng] Announcing new coupler gauges for HO standard gauge and narrow gauge models

Mike Conder
 

Thanks for the order!

Yes, they added the same height (On30 and HO.) But some prefer the One coupler height for their On30 rolling stock as they feel it looks more prototypical. I will probably be designing a gauge for that as well.

And IIRC, Bachmann cars have a coupler pocket that can be changed to the On3 height from the lower HO height.

Howdy:

I don't recall that Bachmann has the adjustable coupler box height; I do know that AMS (Accucraft) has the height to HO standard / adjustable to On3, and San Juan Car Co. excellent kits are set to On3, IIRC.

Designing for 3D printing

William Lugg <luggw1@...>
 

Just out of curiosity, can you point me to a good tutorial or two about designing parts to be printed in 3D by Shapeways? I've got some items I think might be interesting to try, but haven't a clue how to get started.

I am a Linux user and have been fiddling with with FreeCAD a bit, but applying it to the construction of a model of a real part has so far eluded me. I also have the professional version of QCAD available, but I'm pretty sure that's limited to 2D work.

Thanks.

Re: [SergentEng] Announcing new coupler gauges for HO standard gauge and narrow gauge models

I only have a couple of Bachmann cars, early ones, and they had something that looked like a lower coupler box and an upper coupler box.  It also looked like the lower box had to be removed to use the upper.  Not sure if that was the coase, or if later cars had the same design.

Need to ask some On30 guys to get that right.

Re: [SergentEng] Designing for 3D printing

Mike Conder
 

No problem on my part.

BTW, I have some of the the Sergent Engineering assembly jigs that also look like they are made via 3D printing, maybe even by Shapeways, and highly recommend them.  they also have a coupler height "go-no go" gauge that's simpler and lower cost than mine, just works a little differently.

Mike Conder

Re: [SergentEng] Designing for 3D printing

Mike Conder
 

I use SketchUp, a free 3D program now owned by Google.  But I had a hard time until I realized that SU, until CAD, worked better by starting with large shapes and removing "material" to make the item, as opposed to making shapes and adding them together as I normally did with CAD.  Either way works but the "removal" or sculpting method can be a lot faster ... especially with the coupler gauges I designed.

I also did  lot of Youtube videos from a site called "mastersketchup.com."  The owner also has a lot of non-video tips.  I did most of the relevant tutorials, even the ones building a shed, because the skills transfer to model parts even though the subjects usually don't.

Shapeways has a number of tutorials as well, so one needs to pay a lot of attention to the minimum thickness limits of the selected materials.

New to group

Ken Neufeld
 

Group,

My name is Ken Neufeld. I model in Sn3. Wondering if anyone out there is using Sergent couplers in this scale/gauge.

Would also like to know if there are specs on these couplers. Couldn't find any on the Sergent website. Specifically I build PBL kits and they use a Kadee #26 on a lot of their kits. This coupler has a .100 longer shank than the #5.

I am assuming the compatible shank couplers are replacements for the #5 or the newer scale head coupler.

I am thinking I would use the Sharon coupler but don't know if it would be compatible. Or would I have to use the Type E and ignore the vintage?


Thanks to anyone
Ken


Re: [SergentEng] New to group

Sharon and E couplers will interchange. There is also a +.100 shank E head coupler available on the website.

Just using E's will definitely change your opinion on Kadee couplers.

Re: [SergentEng] New to group

David Heine
 

I model in Sn3 and have HO Sergent couplers on some of my rolling stock. I tried them after seeing them on some other Sn3 models. I've been mostly working on my layout, so I haven't converted my old equipment, but the newer stuff I've built has Sergent couplers. The longer shank couplers have solved the biggest problem with changing over to Sergents in Sn3, which is the use of coupler boxes designed for a #26. I've tried several approaches, on PBL and other kits to move the coupler post, but was never really happy with any of them as a solution to go and change all my existing rolling stock. The long shank Sergents make it easy.

They are smaller than the HO Kadees, but are probably as close as we'll ever get to a 3/4 MCB coupler in S scale. Sergent makes some S scale Type E's, but no S scale Sharons.

I also do some modeling in Sn2, and I've been using the Sergent couplers, but because of the narrow track gauge, I have to use the narrow shank version. I, like most others, use HOn3 gauge for Sn2. With Kadees, I'd have to use their smaller HOn3 couplers which look worse than the standard HO ones.

Re: New to group

Nick Gully
 

Ken,
 I have been putting the Sergent coupler in my P-B-L equipment. Since the S Sharon is a shorter shank than the KD#26, I remove the mount hole in the P-B-L casting and drill a new hole to screw into. I put a bit of evergreen polystyrene tube around the screw as a bushing so the coupler slack and side-to-side action feel appropriate to me. They really are a splendid match of accurate operation with scale hardware.
