I had a great time at the show. Got to meet a few RR-Line foamers, I mean forumers.

Ok, time for me to get back to work on this project. I've finally decompressed from the Midwest NG meet. Hopefully, I'll have some photos in a day or two of the build progress.

Sorry, no new photos yet. I'm trying to figure out how to mount couplers and it's got me puzzled. Once I get past this, it should be smooth sailing.

I'M BA-ACK! After spending a week puzzling over how to mount couplers, plus battling Modeler's Attention Deficit Disorder, I came up with a solution. I'm using the couplers from the MT 1017 4-wheel passenger car trucks. These couplers have a tab that is attached to the trucks.

Download Attachment:

As you can see, the tab is fairly long. I trimmed each one to fit the front and rear spaces, and drilled new screw holes in them.

On the front end, I glued a series of pieces of .100 wide strip to form the base to attach the coupler to. To form a "pocket", I glued .030 x .156 spacers, approx. 9/32" long. This left a slot to insert the coupler.

Download Attachment:

On top of the spacers. I glued .020 x .156 strip, approx. 3/16" long, to partially cover the coupler tab.

Download Attachment:

For the rear coupler, I had less space to work with. The base is a piece of .080 x .100 strip, the .080 side facing up. Again, I cut 9/32" spacers, this time from .030 x .080 strip.

Download Attachment:

On top of these spacers, I glued .020 x .080 strip, approx. 3/16" long.

Download Attachment:

Once everything dries, I'll drill and tap holes for the coupler screws.

Here are side views showing the couplers in place.

Now, onto making the pilots and footboards.

Thanks, guys. The couplers do come in handy. Unfortunately, I don't think Micro Trains sells them separately from the passenger trucks.

Nice job, Jeff!

Sometimes that MADD has to kick in in order for things to percolate. This works fine with me, until I suddenly see a solution that should have been obvious six months ago....

Good to see you back at it, Jeff. The coupler solution looks to be a good one.

Jeff - Glad to see some progress! The coupler solution is a good one, but I'm wondering if they stick out too far... especially when using the loco on tight curves. I feel they might cause the first car to derail. I may be way out of line here since I don't know what your curve radius is. Just wonderin'...

The curves are 18" radius. I don't think it will be a problem.

Good! Just thought I would throw that out there.

Anyway, glad you're back at it.

I got a little more done this evening. I cut out the step areas on the deck. Here are before and after shots.

Ok, I have the pilots built. I used various widths of .030 thick styrene strip.

Download Attachment:

The top piece is .100 strip, the pieces on either side of the coupler opening are .156 strip, and the bottom piece is .030 strip.

I found some footboards in the box of parts leftover from my other 25 tonner kitbashes and glued them to the pilots.

Download Attachment:

Once the glue sets up, I'll glue the pilot assemblies to the chassis.

Jeff,

How did you nibble out those step areas on the deck?
