Re: Corrosion on couplers

Dave Snyder
 

Mark, I wasn't suggesting that you spray paint the operational surfaces of the couplers. I was going by Frank Sergents recommendations for
rattlecan spraying the couplers, check his website. Per the Rust-Oleum website, what started as a fish/whale oil additive to paint to the modern
conglomerate is an amazing journey that doesn't readily disclose the chemical complexities of their products, trade secrets I suppose. Maybe you would share your results with us as you progress, I'm always open to enlightenment.

Assembly step 1, knuckle flash

Andrew
 

What is the easiest way to perform step 1 on the knuckle?

X-acto knife (or even better a scalpel) and one of those magnifying fluorescent ring lights.  (Well, I don’t know about “easiest”, but that’s how I do them anyway.  In my experience you won’t find any flash on about 80% of them, but you still need to do the step for the 1 in 5 that does have some.)

Cheers,
Jeff.

Jeff and all,

I should have been more specific with my original question.   How do you hold the knuckle while scraping the flash off of it?

I always hook the pulling face under the fingernail on my left index finger, so I can wield the xacto knife in my right hand with the correct portion of the knuckle facing up. I'm righthanded though, not sure how a southpaw would do it.

I too normally just hold it between thumb and forefinger. It is a bit
awkward until you get used to it but it isn't too bad.

Something I'm going to try is drilling a shallow hole the "diameter"
and depth-to-tang of the knuckle in a piece of wood or something, then
I can just place the knuckle in the hole (the tang resting on the piece
of wood) and then I can just use light finger pressure to hold it there
to clean up the tang.

Tim,

That sounds like a good idea,  I might try that.  I cut one of my fingers the other day while doing this.  Also do both sides need to be burnished or just one?

Re: [SergentEng] Assembly step 1, knuckle flash

You should only have to do one side, the side with the little depression
where the ejector pin pushed the knuckle out of the mold.

I will note that I don't (currently) use a knife for this but I use a
small fine needle file. No cut fingers!

I've not really had any flash in this area, mostly what I find when I
do find something is that the very pointy end of the tang has some extra
material that prevents the knuckle from fully opening (or closing, I
forget which), and this is fairly rare as well.

I was thinking further to my idea and instead of trying to drill a
shallow hole I'll find something, like sheet styrene whose thickness
matches the depth-to-tang measurement, drill a hold all the way through
and then screw or glue that to a piece of wood or something.

Coupler style for 1970 era SP engines

Rob Briney
 

I model the 70s with The SP and ATSF in The Central Valley of California. I was wondering what style of coupler would be correct for that time period for my Engines.
Thanks in advance for any help I can get.
Rob Briney

Re: Coupler style for 1970 era SP engines

Dave Snyder
 

No easy answer Rob. Best practice is to find period pictures and identify by using the NMRA coupler file in this groups files section. Remember that freight and passenger locos could use different couplers.

[SergentEng] Coupler style for 1970 era SP engines

Nathan Rich
 

Most pictures of freight locomotives from that time that I have seen have the usual E heads. Passenger locomotives usually had H heads at that time. I would check roster shots of your specific locomotives to try to find which coupler they had.

It seems to be in more recent years that passenger locomotives and some freight engines, especially those in rotary dump coal train service, have started getting F heads.

Here is a comparison of the “HO” scale Sharon coupler next to a Micro Train Line “N” scale coupler. https://groups.yahoo.com/neo/groups/SergentEng/photos/albums/573633332/lightbox/883904003?orderBy=ordinal&sortOrder=asc&photoFilter=ALL#zax/883904003
 
You decide if that is close enough.

Those couplers are very realistic hopefully they will fit in N scale freight and locomotives

did anyone produce an HO-scale model of the Westinghouse h-2-a type tightlock coupler as used on the BMT,standards,Triplex,and IND R-1/9 subway cars.I am talking about a working model,of the same  coupler.Thanks,and  God bless.

On30 Application

Charles Owen
 

I have completed assembly of two pairs of S scale Sergent couplers that I intend to test on my On30 layout.  However, I am concerned by the lack of draft gear boxes to mount the couplers - I have noted the mention of John Degnan draft gear boxes as well as the Kadee #802 boxes. 


Several questions come to mind:


a).  Are either gear boxes readily available?


b).  Has anyone utilized Sergent couplers on Bachmann On30 EBT coal hoppers - is there a simple conversion process to facilitate this work?


c).  When using the S scale Sergent couplers for On30, is it best to use the couplers at the standard HO Bachmann coupler height or is it better to raise the coupler height to the On3 standard?  It appears that Bachmann On30 equipment was built with that possibility, even though the couplers are supplied at the HO level.


The use of Sergent S scale requires a rather expensive conversion process and hopefully there is a reasonable solution to the questions above.  I really think that the realistic appearance and operational aspects warrant the fullest consideration of the Sergent couplers.


Thanks for your thoughts.

Re: On30 Application

Hi. I too model in On30 but my prototype is more like Maine two footers so I have gone for Shannon style.     A lot smaller than your S scale coupler.   For me I did consider using straight HO but decided to go smaller again.  Have you considered using straight HO instead😊

Mark from oz

Re: [SergentEng] Re: On30 Application

Nathan Rich
 

It depends on what you really want to do.

I think that S scale couplers at On3 height is the best way to go if you are modeling something that used 3/4 size couplers and you are going for the closest to scale that you can. I believe the D&RGW used full size MCB couplers, which also enabled them to switch standard gauge cars on dual gauge trackage. I think that HO couplers at regular HO height is a maybe sort of okay compromise but they certainly aren't scale.

It does not appear that Kadee offers coupler boxes independently of their couplers, though you might ask them if they'll sell you a bunch.

KD does offer their S/On30 box but do not catalog it.  You must call them.

Another option is the box from SMMW:
