This week I pulled out and trimmed a couple of the planks that rubbed badly and things seem to be running smoother. I also did a test run with the wall set to 30° overhang. Aside from the climbing being really hard (I seriously need to buy some holds with texture) it ran pretty well.
On the back side of the wall the chain was dragging on the cross members (due to the previously discussed lack of a track on the back side) but it wasn’t noticeable. I still think I will try to fix this in the near future, just to prevent undo wear on any components.
I am very impressed with how solid the thing feels with the wood in place. I had added more bracing to the design after playing with just the frame, but now I think I will take it out.
BUT when I put the wall back to vertical the damn thing seems to stall before ramping up to full speed. I’m not sure what the problem is but I’m guessing it is just a tighter fitting plank binding. I guess we’ll see.
