3D Printed Coupler Pads for Atlas RS-1

CentralFan1976OGR Forum Member

We are up and running!

Here are the latest builds; coupler pads for Atlas RS1s. I've tried to simulate what the actual coupler system looked like. Not all railroads had full pilots on their RS1s, NYC included (see picture below), so emulating this was relatively easy. What's great about these is that there is already a 2-56-sized hole in the pilot in the correct location, so all you need to do is tap it and run a 2-56 x 3/8" machine screw in and DONE!

(The gray pilot spacer is actually an Atlas factory 2-rail part, available from AtlasO.com)

Thanks,

- Mario

Nice work Mario.

I picked up the Atlas parts some time ago, then promptly picked up an additional RS1. Never got around to installing the parts because the locomotives are such a pain to take apart. Guess I need to get busy.

Thanks guys!

Matt, good too now as I was going to send you a set to try, anyway, for you thoughts.

Thanks,

Got the GP30 spacers and pockets today. They look good. Going to see how they adapt to an MTH GP30 over the next few days. Will report back.

Thanks Matt!

As I had mentioned, please modify the pilot spacer to fit and then mail it back so I can take measurements and create an actual drawing for the MTH GP30s, and I suspect also the 35s.

Another set are on its way to you to keep and install.

Thanks,

Mario

In case anyone was wondering, these have been redesigned for a more prototypical look.

Ok, here's the final design on the RS-1.

I added a few tricks.

Looks really good. Dropped my orders earlier today. I take it I am the first for the RS11s? or do you have a pic with it installed. Also why the two different type of spacers?

Doug,

The two different RS-11 coupler mounts have some subtle detail differences, with the open space removed on the "Experimental" one...

They should fit into the opening, but I haven't gotten my order yet to test them. I'm going for a minimalist approach.

Thanks,

Mario

I was talking about the spacers. So that means I am part of the experiment too?

Those are a little different. Well, a lot different.

These, I designed them to slide on the end of the frame, because of the big gap between the frame and the shell.

these represent the back side, with a slot for the frame. The square hole is for the front railing screw.

So I played it Safe and ordered both. Either way I glad to inadvertently be helping validate the design. In the next couple of days I take the measurements for the MTH GP pilots and depth of spacer so you can offer an product. Same as for the SD 24 if you want. The redesigned GP 30 fits without modification but still need some adjustments.
