As you can see in the bottom photos, I have lumber for the construction of the benchwork. The first phase of construction will be helix #1 in the alcove at the far left corner and helix #2 in the far right corner, around (actually above) the well tank. Zero elevation will be at 50" above the floor with the two staging areas at a -18" underneath, or 32" above the floor.
So, l'll get started today and keep you posted on my progress. Until then . . . keep your hand on the throttle and your eyes on the rail.
