Progress on the return loop.
Started by gluing the roadbed spacers down.

I found that I didn't have to cut the spacers into trapezoids. Simple 3" long rectangles worked perfectly and left the track centerline visible between them.
Then the N-Scale cork road bed was glued and pined.

After the second curve was done I lined up module B to glue the bedding track pieces in place.

To make sure they lined up I slid pieces of rail in them. Should give me near perfect alignment. Maybe.

This was all done in the early afternoon in the hot sun.
Took a long cool break.

Late afternoon the sun had moved and left my outside work area in the shade.
More work on module B.
I laid out the back 30 degree curve and then glued the connecting pieces down.
The front right one now lines up with the front main on our modules. This will create a gentle reverse curve. Should not be a problem.
The glue is now drying. If time permits I will solder some track together and start gluing track down on module A later this evening.

I used BG4 track pieces as connecting pieces on module A as that allowed me to use R6 for the curves. To go to a larger curve would require a module more than 24" wide. I am using BG2 most everywhere else as that is what I have a good stock of.
I am going to have to order more track to build a second loop. The problem is that a box of BG2 and a box of BG4 don't add up to much. Will have to see if there is anything else I really need to spread out the shipping.

A few thoughts on scenery.
Here is the current plan of the loop.
Teardrop End Loop.jpg

I plan to scenic only the front edge around to the center of the loop. Basic grass, ballast and bushes. Nothing that can't survive transport. The rest will get a coat of green paint and maybe ballast for the track.
The center is currently open. Might be a good location for a large industry. The connecting turnout will be installed but will go no where for now.

If you want to prevent sagging, gluing a 2" strip of 3mm harboard on the edge should do the trick.

If you want to protect the foam edge from dings, you can use drywall metal corner bead. It is thin aluminium, lightweight and comes paper-faced so it can be painted. It's 11/16 wide, but should be enough. Home Depot sells 10-foot strips for $4 each. Make sure you pick the outside corner, that one has the paper on the good side.

Using a combination of hardboard and drywall corner would solve both problems.

The increase in curvature from R3 (15.6" R) to R6 (20.7" R) will look and operate much better. I expect everything to run better on this loop. I admit that I was a bit worried about the reverse curve on the bottom of Module B but a little doodling this evening has shown that it is 10 degrees of R6 on each end with a foot plus of straight track in the center. Should be no problems for any of the equipment we run.

I had contemplated making this in more pieces but . . .

that would mean more joints to figure out how to keep together. As well the filler piece would now become a full module with the need to make some sort of alignment mechanism to hold it firmly to the two adjacent modules.

Also you would loose the centre area. Not sure what to put there yet. There is the small staging yard idea, or the passenger yard idea, or a large industry. Maybe a mountain scene with a track climbing up to a mine. I'll leave that to someone else to design and build.

For now I will stick with the three big modules and a floating filler piece and see how it works. The setup at BCSME next month will show how well it works. The four foot sections are light, much lighter than the current wood turn back loops. Should be much faster to setup than six separate pieces.

If they prove to be a transportation problem, I can always cut them up.

Working on modules inside today.
Cork road bed is drying on module B.
Glued track down on module A.
20190602_gluing track on module A.jpg
The foam top looks a little distressed because I had to sand the cork road bed so the track lined up better with the bedding track connecting pieces. Tried to sand in a bit of super elevation.
Module A will be put outside to dry. That makes room to work on module C.

Most connecting track pieces glued down. Short of insulated rail joiners. Will get more tomorrow and glue the final piece down.
20190602_gluing module c.jpg

On the background you can see the cork drying on module B.
Later tonight I should be able to glue the track on module B, and the cork on module C.
Tomorrow I should be able to glue the track on module C.
Wiring will be later this week

These large end loops will require redesigning the NMRA Show Layout.
