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

Re: Corrosion on couplers

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.

Hi Dave.

Thanks for your reply.  

I am sure someone will correct me if I am wrong.....but it is my current understanding is that ruskolium is a product that uniquely has some sort of propitiates that make it much better than just using a generic automotive undercoat for these couplers.  It somehow acts as a anode and is not just a covering for the metal.

Secondly it is again my understanding that when you paint the couplers the instructions require not painting the operational surfaces so as not to interfere with the fine tolerances involved.

What I had envisaged was first painting as specified in the instructions then brushing a tiny amount of No-Ox on those working surfaces.  Ensuring I get off as much of the No-Ox  off the coupler before final assembly.  

Using No-Ox "may" protect the unpainted portions of the coupler.

Mark

Ps that ebay No-Ox seems cheap, thanks for the heads up.

Re: Corrosion on couplers

Mark, I would think that any spray can automotive primer paint would coat the Sergents and inhibit any further oxidation. And even Rust-Oleum doesnt remove the oxidation, it just binds to it. The NoOx is a grease like substance that I have tried with mixed results on rail and wheel wipers, etc.
It really did not remove oxidation well and polishing the rail before application gave the longest lasting results. I doubt paint would adhere to it
well because of its petroleum properties.

Funny, i haven't had a problem with oxidisation with my sergents and i am in Queensland, i don't do anything different from what i have seen other doing,  mind you i haven't got my new non painted ones built, so maybe that has got something to do with it

I'm not so sure that humidity alone was the cause of the problem, it can
get quite humid here and I've not experienced it, assembled or not;
though my assembled couplers seem to get a good amount of graphite in
them when using the pencil.

The white powder is oxidisation, essentially rust for Zinc. The only way
I can think of to get that much oxidisation is a galvanic reaction
between the zinc coupler and stainless steel ball, and given the size
of the ball that's got to be a huge long shot.

Anyway, nice to see another Oz member (from my state to boot) here using
Sergents.

Don't you just love the way some computers "improve" what one has written.

The product is Sanchem no-ox 

Sorry for my computer's interference in what I intended to write.

Have a good day guys.


Re: Corrosion on couplers

Mark
 

I know I'm responding quite a bit after the discussion has more or less ended.......but has anyone thought to try using Sanchez no-oxygen product.

It evidently works by not allowing oxcedisation to occur.  People swear by the product to stop oxcedisation of track thereby improving electrical contact.  So just maybe it might protect couples from "rust" build up in lightly used couplers.

Then again it "may" cause couplers to not work at all.

I figure it has got to be worth a try.  Given that we can't get rust oleum in the right colour here in OZ I think we have to find a solution for this problem.

I do remember Frank saying that he was moving away from assembling
couplers and just offering the kits.

If you need assembled ones I'm sure there's plenty of people willing to
do it for you.

If you are placing your first order, remember to get an assembly fixture and an uncoupling wand!

I can assemble them 5 at a time without a fixture but I've also assembled about 500 couplers by now, I've lost track.

If you have older cars, Sharon couplers are also an option, they will interchange with the E couplers, I like to mix in a few because it provides a little variety.

If you do not feel comfortable with the assembly process, contact me off-list and I can make something happen for you.

Re: Need sergent advice !

Hello ?, nice to sign your posts so you can be addressed correctly.

The Proto 2000 Steamer says Kadee #5 couplers so the Sergent EC87K should drop right into the pocket once you have removed the lid and screw.

The Southern Car and Foundry units appear to be Kadee #5s, but I would query the company to make sure as well as inquire as to any perplexities with coupler change out.

The Westerfield resin kits are less trucks and couplers, so you could buy Kadee #5 pockets and install  as above or try the newer scale pocketed EN87A couplers and don't forget to order the trucks as well. These resin kits will need assembly with various adhesives, painting, and decal application and over coating to protect the decals. They can be daunting to complete, but a lot of modelers enjoy the adventure.

I would start by using the assembled Sergents at first.
Check back with the group as you progress and feel free to ask questions.
