I've looked at the rapid transit style couplers but haven't come up with any simple way to create an accurate, operating model. At some point, I just get too far out of my comfort zone. You might contact Andy at the Proto87 stores site. I happen to know he shares some of the same interest and is probably capable of coming up with a good solution.

Effect of dampness on steel balls

Alan Hummel
 

Hi,I've got a very damp&wet basement in heavy rains. It's always nice&cool in the summer. In Winter that gets to be a problem if cold bothers a person.

What I'm wondering,is if this dampness&on occasion wet basement will corrode the steel balls that lock the Sergent couplers,causing them to not open&close properly.

Thank you.

Hi Alan, I cannot answer your question with complete confidence. But with 10 yrs of Sergent HO coupler use on 250/300 cars, my only failures were with cars dropped and landing on the coupler. The balls exhibited no signs of corrosion, but not having kept records of installation dates and only 2 occurrences I can offer little time relevance. My  location has hot humid summers and cool/cold winters (this one has been colder than you know what) and other than the aforementioned disasters I have had no problems with my Sergents that have required replacement. I'm not a metallurgist, but by the balls appearance, I suspect they are plated or stainless steel.

The balls are made out of magnetic stainless steel so they shouldn't corrode. 

I think it says right in the descriptions and/or instructions that the balls are stainless steel.

Thank you Dave. Yes,this Winter has been 1 for the record books at least at my location,as far as actual weather records,it might not have topped those records.

I never thought about the effect of dampness&moisture on the steel balls until yesterday. But I'm moving from a 4'x8' upstairs dining room layout to the basement after May when we have an auction which will for the most part clear my 17'x40'basement for trains. Well,I'll leave Mom some room,ha ha!! I've notice a little rust on some metal axles on a 50' boxcar from Exactrail&that's what really got me to thinking. I suppose the only way to be 100% sure,would be to buy some steel balls&expose them to the elements.

I hope Frank sees this email&he could give us a final answer.

Thanks much for your reply,it gives me a lot more confidence I'll be okay.

The likelihood of corrosion or rust developing on the steel balls used in the manufactures of the Sergent couplers is extremely remote. Rust or oxidation is a result of moisture collecting in microscopic imperfections of the metal surface of these polished steel balls, These steel balls are polished to remove these imperfections. Also the material used in ball bearings is of a high nickel content which resists oxidation.

I have in my junk drawer a collection of ball bearings that have been there for probably 35 years and none of them have developed any rust and the humidity in my geographic area typically swings from 30% to 80% thru the course of the year. If anything in the Sergent couplers will develop oxidation it would be the  zinc alloy of the casting itself. With that if any form of dry lubrication is used in the assembly this probably will not happen as the lube product will also reduce the collection of moisture on the casting surface. In closing it is doubtful that the development of rust / oxidation of the Sergent product would occur if even they were submerged in sea water.

Thank you very much that's what I needed to know. I'm making the change to all Sergent couplers,but thought if corrosion could develop on axles it might happen with the steel balls. I been tossing & turning,trying to decide whether I want to stay with my HO collection of 30+ years,or take the chance of moving to O scale,which at present,closely ressembles HO scale offerings 40+ years ago when I was introduced to HO-not much there. Oh it's come a long way,but has a lot further to go&if you don't custom decorate&have a lot of wiring skills,you're in trouble. I've got a vasr amount of HO items that when I bought them,went for a high price,that now days,you can't give away.

Thanks so much again.

Alan,

I feel your pain with the value of you models diminishing over the years " I've got a vast amount of HO items that when I bought them,went for a high price,that now days,you can't give away."

I have new product, in sealed cartons, That some individuals consider their worth pennies on the dollars. Nobody wants to or has the ability to assemble a kit anymore.

John Degnan
 


Frank, do you produce the Glatzl couplers, or are you just an outlet for them?  If you are producing them... would it be possible for these to someday be available in S scale?  The one and only "dummy" coupler that I know of in S scale is extremely poor in appearance.

 

Thanks.

I too love assembling kits, and strangely enough I love assembling the sergent couplers.  I have only been looking for one kit at the moment, and that is an intermountain r70-20 undec refer, no one has them anywhere. But if I can find a kit that fits my 1990-1996 era for the right price then I buy it.  As far as the steel ball goes, I have not had any issues what so ever, and living in Brisbane we get some really good humidity changes which cause great issues with my glasses fogging up.  in fact the only problem I have had was when I used my fingers to put them in (only did it on my first few).  The ball stays stuck down or up, so from now on I always use tweezers to insert the ball and make sure the couplers are spotless with no flash or debris anywhere, needless to say  don’t have any issues now,  will have to pull apart the old ones and clean them up to free the ball again.

From what I can tell, the IM 57' Mech kit has not been released yet, so sez my local hobby shop.

Now, for the pre-built IMs, has anyone successfully installed Sergent couplers in one yet?  I start into it, but stop at the sound of popping and cracking plastic sounds!

Jason, good Lord, I can't get them in easily with surgical tweezers. I don't know how you did them by finger. Even then I had to use an Optivisor and Ottlite, not to mention a few dirty words and nasty names occasionally.

I like building kits also.

This week I'm building three Intermountain PS-1 box car kits.

The first one is a 50' car that was put out by the UP Historical Society some years a go. A friend of mine had three and decided he didn't need all of them so he gave me one because I had no Union Pacific cars. From what info I could find the prototypes were built in 1967 or so. So I built the model with ladders all the way around, Moloco PS cushion pockets with Sergent compatible shank couplers and ExactRail  Barber S-2 RB 70T trucks.

The other two cars are Cotton Belt 40' PS-1 box cars with 8' doors. I bought these maybe 20 years ago. I never looked at the kits until this week and saw they came with the wrong instructions!
I'm building them they way they appeared in 1980 at the end of their lives. I'm using narrow shank Sergent couplers with scale width boxes on these along with Plano running boards and Kadee trucks.

I build almost all of the Sergent couplers I use. I found that the narrow shank Type E couplers work better than the compatible shank Type E couplers. The compatibles take more break in time.

Jim,

The undec IMRC R-70-23 reefer kits were released a few years ago, I have two of them.

From what I understand about the RTR reefers, they are/were set up for Kadee 78 couplers so they have that strange center post on the coupler boxes. IMRC was supposed to change it so it could take Kadee 158 couplers, which would be the same as Sergent compatible shank couplers.
I just checked my spread sheet and I have 10 of them. One from the first run and 9 from later runs. I haven't taken the coupler boxes apart on any of them to see how Sergent couplers would fit.

Jason McKee <jdmkee@...>
 

Yes the second or third batch hasn’t been released, still waiting on that one, as far as using my fingers, well I licked my finger then used that to hold the ball, took me a lot longer than the tweezer method, hence I stopped, plus also I saw somewhere that the oils on you fingers can cause the balls to hang up.  I still have the odd ball go into orbit every now and again, the Tamiya tweezers I use work really well.  The balls make good ho scale “space Debris” if they ever come back to earth on the layout J

 

As far as fitting the intermountain RTR, not too sure what glue they use, but if they are like the kits, the coupler should come off with a little wiggling, without seeing it I couldn’t say.  Maybe try freezing them then try to open the couplers up, may make the glue brittle enough.  Also there isn’t any screws hidden anywhere that need to be removed,  sometime the trucks can be helping to hold the couplers in place.

A possible suggestion...there are tweezers designed for jewelry making called pearl tweezers. The ends have little circles instead of points so that you can hold a round object securely. They come in several sizes. Either Rio Grande or Otto Frei are reliable sources. I haven't tried them yet, but certainly will when I start assembling my Sergent kits.

Taking the Plunge

Nathan Rich
 

Happy Easter!

I am about to take the plunge and order a bulk pack of Sergent couplers. I have a few cars with them already on and they look SO much better than any Kadee coupler.

Does anyone have any tips on doing a ton of coupler assembly at once? I am 25 so my eyesight is still there and I don't have the shakes or anything... 

Plan is to get the couplers ready then pull everything into the shops and convert all at once.

Thanks in advance!
Nathan
