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

Franks original couplers were cast in pewter. No bad reflection on Frank as it's how he started and you have to start somewhere but the couplers were just ...a pain to work with and the strength of

Chris, Awesome to hear! Thanks for sharing that info with us. Hopefully it will all workout well regardless of which process you have to use to make the couplers.

Chris, This is great news as I am still in need of F and some H couplers. I hope you can continue the entire line at some point. James Wall Rural Hall, NC

I figured I should add in here since I am the other one "talking to a company"...I shared with Andrew but figured we are far enough along I can share a bit more publicly...although I won't say what

Andrew, That is awesome hopefully the bugs can be worked out to where they will end up being flawless after production. I too sent an email to precision scale with no response as did several others

That looks good Andrew. On the dimensions being slightly out, do remember that Frank said that the parts are done for the 3d printer he had (something about a hole being slightly oblong so the

I have been in contact with Precision Scale myself, although I need to touch base again as my last email didn't get a response. On the Facebook group Christopher Costello has mentioned there may be a
