Kevin I finally found the time to assemble and install a pair of the printed couplers I was sent. I had to slightly enlarge the ball socket so the ball bearing would not stick in top pocket. I did not

Great to hear this update Kpack! These are great news, i would also like to know if you would consider to send some amount of your test versions (of course i mean SELLING) :) Take care and stay

That’s great news Kevin. Does this mean you’ll start selling them (and other versions)? George Sebastian-Coleman gsebastiancoleman@...

Just wanted to follow up on my findings with printed couplers. I have installed 6 sets of type F's on grain hoppers (metal knuckle) and have extensively tested them. I have not had a single failure

Enjoy prototype modeling the contemporary/modern era in HO scale, especially the Vermont Railway System and New England Central in Vermont.

I like to model csx coal trains Chessie and up steam I am very interested in this product

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. -- Go Sell crazy someplace else, we are all full up here.

Do not know if anyone ever replied to your question. The "S" couplers are already designed. Getting them done is why I am rereading these old messages. Frank has a supply of "S" type E knuckles.

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 ge

Thanks Steve. I'm bidding now

A number of Sergents just popped up on eBay - double shelf's and the like. I'm not interested but I imagine some of you are.

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

I would like to find assembly tips and what others are doing. Get Outlook for iOS

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

I appreciate the history lesson...that may sound sarcastic but it really isn't meant to be. I'm actually very skeptical that spin casting will work, and not even because of the strength of the

Should have mention Frank and I were only discussing the material utilized in the latest versions of his couplers ... not the original couplers. I defer to anyone with that knowledge ... V/r, Tom C.

Thank you Steve ... this Group has been so friendly and helpful that I don't want to see any strife created ... we all have the same goal of keeping Frank's amazing couplers available for those that
