'nother rebuild. This feature is called Sleeveless and is actually just before the "ravine re-route" photos from the beginning of the thread…if anyone actually reads what I write. The original was OK to ride, scary to walk on. The "stringers" were 1.5" x 1.5" laminated maple steamed into a nice curve. It all seemed like a good idea, but over time it became clear that we could both make the jump nicer and more sturdy. It had a tendency to buck riders, which caused them to slow down and ultimately case the landing. I should note that this was built before we used chainsaws.
Clicky for a shot of the original...
Here's the rebuild. Same "essence", but with good and beefy stringers, nothing to case, nothing to buck you and a nice fixed up tranny. First one to tire tap the tree gets a gold star! All the deadfall laying about is to dissuade the "I'm not a freerider so I'm not going to ride on your wood" crowd. There's a lot of them.
