Stephen, I believe I can recall a post made some time ago, stating the couplers were made of an alloy called "Zamac 3". Hopefully this is still somewhere in the archives. Best of luck. Jamison Amis

Does anyone know what kind of metal the couplers are made out of? I am looking into casting my own. Stephen

Hello all, I'm a Sergent user and I am running out of certain versions, so I came here to learn about those who are 3D printing their own couplers. Going back to Kadee is not an option! I model

Hey Mr. Sergent Do you see any possibility to try these strong resins as a possible future product on your website? If it takes some pre-investments into a printer or something i have an idea: what

Hello, I have been transferred to this group from the former Yahoo Groups forum. I have used Sergent couplers for over 10 years now and would like to keep up to date on the future of the couplers.

I contacted you on YouTube via comment about these couplers and recently joined the group. If you could help me secure long lower shelf sergents for my center partitions and double shelfs for my tank

For those that contacted me regarding testing the printed couplers, they will be going out in the mail tomorrow. I have all of them printed and cured, just need to package them up and send them out.

Rob, If you don't find a set of couplers contact me off list about 3D printing some. Andrew DeKruif

To more accurately complete a project on a Rapido RDC-3 I am searching for a pair of Type H couplers, HC87K. Actually a dummy set would work fine, as the RDC will be run solo. Thanks, Rob

Jeremy, I tried to mail you off list but I don't think groups.io played nicely. I'd like the HO scale lot - can you mail me at steve_wintner at yahoo dot com ? Thanks Steve (and sorry to the group

Does anyone happen to have about 35 pair (at least) of the Type F couplers preferably with the M040 shank? I have a train of RD4s that needs them

EC64 have sold. Lot two asking price is $35 + S&H

Adding Sergent couplers to the new Walthers G85 flatcar is really easy. The trim piece at each end needs to be removed by lightly prying with a #17 blade toward each end, as they are lightly glued.

If the EC64 couplers are the NEW (improved) style than I'll take them. If they are the old (original) style, I don't want them. Thanks. John D
