I've spent the last couple days working inside the big helix, installing 4 Tortoises and connecting track feeders to the power buses. Three of the four are now done. I'll get the fourth tomorrow. Because they are in the helix they require a slightly different mounting style.
The secret is this L shaped piece of plywood.
I made 3 of these for the switches with tracks directly above. The fourth one is a little different, and will just be mounted to a simple plywood block.
The Tortoise hangs down out of the way of the track.
If I had known they were going to be this easy to do, I would have done them long ago.
