I also have been testing the bronze couplers that Andrew had made, and as expected they work great.  Not to mention they are beautiful in their natural "gold" shine.  I almost don't want to paint them.

we talked about up-scaling and then installing a non ferrous metal into the hole where the ball bearing resides to use the same size as HO.

Hi,

I model the Southern Railway in ho scale, heavy into their passenger train operations, from 1972-1979 before the NS merger.
Over the last few years I have worked on getting my models more and more realistic and this included the possibility of installing Sergent couplers.

Since so many styles have became unavailable I hope to learn to make my own or support someone who will develop this process by purchasing from them.
I had talked to Frank about the "H" tightlock couplers in the past and hope they will become available again real soon.

Thanks for your consideration,
Rahl Smith

Hello, my name is Jonah, thank you for the add to the group. I model modern BNSF in ho scale and have taken an interest in sergent couplers. I enjoy how they operate similar to the prototype and are more of a scale size rather than kadees. I eventually plan on converting my whole fleet of engines and rolling stock to Sergent couplers.

I have sergent couplers in use on my layout.

Steve,

Thanks for that post link back. I stand corrected. I must have missed that post somehow and when Frank had mentioned zinc in another post I took that to mean pure zinc.

Chris,

No sarcasm detected. I think your on the right track looking beyond spun cast so early on in the piece, and I think the shapes of anything but the standard and lower shelf E may preclude them from being spun cast easily anyway.

I think Tom is right, the collective might of the minds here can make the couplers being available again happen, it's just taken us awhile to get some steam up.

As for dies (presumably for diecasting), that's a road I wouldn't go down just yet personally. I'd concentrate on the investment cast types (double shelf E, Type F, SF, H etc) and if you do a good job of them Frank may just live up to his statement and sell the dies to you at a price that you can not refuse.
