Investment cast couplers: Nice to see someone doing this! The balls are easy to get from Amazon or similar, a package of 1500 1mm balls is $7.49 at last check. Used these to assemble a bunch of "Genui

Might be possible to 3D print you something but it would be a dummy. Do you do a lot of facing point switch moves? Nathan Rich

Mr Glatzl stopped making them.

Tim- Thanks for your comments Knuckle pin vs stubs is definitely on the list "to improve". I have seen the couplers with the sprung knuckle as you describe, but mostly the ones I have seen are not spr

Thought you guys might enjoy this, I upscaled the H coupler to 1:8 scale, for 7 1/2" gauge. I wanted to test the theory, because I wanted to use a correct H coupler on the front of a PA locomotive a f

The dummy couplers are great for say between A and B units of a permanent set. I have a set of Alco FA's with an FB and it is very happy with dummy couplers between them. Also keeps people from breaki

Diaphragms do not preclude the use of sergent couplers, you just have to use an MWRY uncoupler tool which is designed to work with passenger equipment. Nathan Rich

I'll vote for moving now, we dont lose functionality and Yahoo Groups is basically dead. Nathan Rich

You could also get a reloadable prepaid Visa card. Nathan Rich

A friend who converted his whole layout has a few, they take compatible shank E's. Taking the car apart is the hard part. Nathan Rich

I still do, sorry for not getting back sooner... I was about to reply then a train went by... Nathan
