Using Domino to secure flexible edging on round object

I am building a train layout for Christmas.  The layout is circular, and is about 36" in diameter, made from 1/2" birch plywood.
I'd like to add some edging to it, with a bit of a lip to help prevent the train from falling to the floor when it gets bumped (it will be elevated).

The edging is 3/4" wide banding that's about 3/16" thick.  I was planning on wrapping the edging around the inside and outside of the layout, gluing it, and fastening it with either 4mm dominos or 3/16" dowels.  If I used the domino, I'd punch through the edging into the layout base.

Has anyone used the domino to fasten edging on something circular?  Of the two methods, which would you recommend for ease of installation and aesthetics?
 
I would use yellow glue and 1 or 2 web band clamps.  This does not sound like a good Domino application to me

+1  Don't see how dowels or domis would add anything to the ample glue surface on that edge.

You may need to cut some kerfs on the inside to achieve the bend.

It will be easier if you first glueup gets you all around the circle, except for a small gap, then carefully size the last piece to nicely close the gap.

Agree completely! Even if this concept was somewhat possible, all the domino slots would need to be wider than the tenon otherwise as you do the wrap the slots could not make the bend over the dominos - you need a straight on push in order to align the dominos to their respective slots. Nice try though, sure is fun using the Domino  [big grin].
 
When I make Lazy Susan's for cabinets I use sheet metal strips I get cut at the sheet metal shop. Works well and the edges are not sharp. Perhaps they would work for your train table.

I have to ask (nice workmanship by the way ...) why you mount the lazy susans on a shelf (bottom of the carcass not withstanding) rather than on a centre axle?

This is not a criticism, just a question.
