|Testing clearance at the hole in the wall. There is only 3.25 inches here due to a stud and a closet wall on the|
far side, but it should be enough.
When I was a kid, my friends and I loved building models. After playing with them for a while, we usually found creative ways to destroy them. From soaking rubber band powered planes with lighter fluid for one last fiery flight, to putting firecrackers in plastic battleships, to melting toy soldiers, we were destructive little monsters. That trend continued when I was trained as a combat engineer in the U.S. Army. They taught me how to build bridges and then blow them up. They even had the insane idea of sending me to Atomic Demolitions School, so if you ever need to nuke anything, look me up.
|Deep into demo|
|Demo is almost complete.|
I need to pull the plywood sheet out as I need to drop the track 3/4 inch as it traverses from Clairborne Creek to the stair landing. A drop of 0.75 inches over the 20 feet of run is about 0.3% grade. That shouldn't be an operational issue.
While I was doing demo, I was also gluing the road bed wedges together to make the curved roadbed sections. Once I had the full sized curve sections, I began detailed survey to see how things will fit. The main constraints are the height of the stair landing and the gap in the stud by the hole in the wall. I am fortunate that the gaps is 3.25 inches wide, more than enough to clear one track, even if it is on a curve.
I am making the curve roadbed with the previously cut wedges. I am using one domino and two pocket screws to hold the wedges together. The screws act like clamps to let the glue dry while the domino provides strength and alignment.
