Re: investment casting couplers

Jamison Amis
 

I've always made it a point to use graphite, not paint, between any surfaces that will make sliding or rotating contact with another one in the couplers I've built.  Imparts a nice "dirty steel" look and greatly reduces friction in operation.  Never had it rub off to the extent the metal beneath was visible, which I believe would only happen if one were persistently applying enough force to deliberately remove it, which is likely far less than what the couplers would be subjected to under normal operating conditions.

Using paint on a contact surface I think is a bad idea, because of the tendency for paints to interfere with smooth mechanical action in these tiny couplers.  This is the major reason I stopped buying Frank's pre-assembled examples some time ago, as he tended to spray everything you could see, and often created a more troublesome build in the process.

They certainly look really nice. The one issue I can foresee though is the material being used. After a few hours in operation a fair amount of paint will have worn off the coupler faces, revealing the bright brass underneath. With Sergent couplers it wasn't much of an issue since the darker metal looked realistic when showing through the paint.

Would it be possible to get some of the tailor made ones for the Walthers Heavyweight cars? Also would it be possible to have you do an investment casting for a Custom Steam locomotive smokestack too?

Great to see the progress being made on these, Lei.  I'm sure I mirror the sentiment of virtually everyone here when I say I'm looking forward to trying your product once they become available.

Thanks for the efforts you and your team have put into reviving and expanding the line, and for being so receptive to suggestions and feedback.

I know this looks like they are made of wax, yes they are.

But, they will be transformed into brass after ​24 hours.

My design will also use a spring in slot. But if you mean exactly the same as sergent, then I have no plans to do it yet.
Thanks Dave.
Thank you, Lei. I can see your slot design on your wax masters. That
was what I was hoping to see, not necessarily identical to Sergent. I
really like the look of the different shank lengths you have designed.
Thank you for listening to our feedback about those. These look great!

I might consider putting it on ebya for sale later.

Lei, thank you for continuing to develop these couplers. They look great so far. Will it be possible for you to offer the same style of shank as the original Sergent design with the slot for the spring?

I’m looking forward to ordering many of these when you are finally able to sell them.
