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

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.

I have just temporarily assemble several cars, including the (Sergent) couplers. Because I intend to take them back apart, and because it's kind of a pain to assemble everything, I decided not to put

As my just posted topic of assembling different lengths of the EC87 would imply, there are times a person has to or wants to use the "compatible" shank couplers. The long shank cushion-style comes to

I recently assembled my first EC87's using Sergent's assembly fixture. I also wanted to have some of the short and long versions of these, and I preferred using an assembly fixture instead of, well, w

I used to paint my Kadee's with an appropriate mix of Floquil--no regrets. I expect to spray paint a batch of Sergents in the future, and will likely use my airbrush to spray some equivalent color of
