Tom, Your files only add up to 53.34 MB, so I suspect the 194 MB is the total in Files. I think we get 1 GB, so we're 20% full, then. That said, I do hope the list owner will give some warning regardi

In the Photos section, I have placed two photos of a passenger car uncoupler I made. I also included directions for making one. The name of the album is: "Homebuilt passenger car uncoupler" I will tha

Mark, What is "they are not made"? I just check the Sergent site, and they're for sale. Admittedly, to a limited extent. David, It would be nice to know everything about an item before using it. The b

Randy, The best thing you can do is look over the old messages, Ed Edward Sutorik

Thank you, Frank. Ed Edward Sutorik

I would like an answer to my question of March 19, 2019. Please. I am referring to, if it is not clear, to part number MWRY. Ed Edward Sutorik

So. About that passenger uncoupler: Will it be again be made available? When? It has been out of stock for maybe 6 months. Ed Edward Sutorik

Or, for that matter, the passenger uncoupler. Ed Edward Sutorik

I put the springs in with an X-acto blade. I put the pointy end of either a #16 or the pointy one between the coils. Then I can pick up the spring and put it in the slot/hole. I rarely lose a spring d

Andrew, Thanks for pointing that out. I missed it. So he needs a new printer. And doesn't like the folks who made the old one. Sounds so familiar--I bought a Canon iPf 5100. Ink jet, not 3D. I surely

Investment casting doesn't use injection molding equipment. Reading this article: https://en.wikipedia.org/wiki/Investment_casting there is a comment: "In recent years the production of patterns using

I understand how using the 3D printer works. I just don't see how it's a necessity for producing investment cast coupler parts. There IS the old way. Ed Edward Sutorik

I think the Athearn trailer flats look more correct with the Sergent short-shank couplers. I am wondering at the need for a 3D printer to do investment castings. It may be a convenience, but I don't s

The "Drawings" folder in "Files". And the patent: http://pdfpiw.uspto.gov/.piw?Docid=06308845&homeurl=http%3A%2F%2Fpatft.uspto.gov%2Fnetacgi%2Fnph-Parser%3FSect1%3DPTO1%2526Sect2%3DHITOFF%2526d%3DPALL

What is the alloy that the investment cast couplers are cast in? Ed Edward Sutorik

Alan, Thanks for the info. While perhaps workable in an emergency, I don't intend to operate in a "continual state of emergency". That is, I either convert a batch of cars to Sergents, or I don't. My

Regarding the dummy couplers: I recall Frank saying the dummies were discontinued and that he had enough to last for awhile. I tried to order some "after awhile" and couldn't find them on the website.

Yes, it would be nice to know when all those couplers might be back in stock. I've got an assortment of projects waiting, and I'm wondering whether to pack them up and clear the bench. And an answer t

Several months ago, it was announced that the Glatzl dummy couplers would no longer be carried by Sergent, but that there were plenty left. I wanted to add some to my order, and can't find them on the

Thanks for your responses, folks. It's not slack action I'm concerned with. Well, in a way, it is. THAT is one of the reasons I've been installing Sergent couplers--there isn't any (to speak of). No.
