I see a router and an edge trim bit in my near future to trim back the over hang on the deck.
I've started work on the seats. The slats look really nice with the deck oil on them. I just broke the corners with sand paper. The wood has a wavy grain, back and forth a few mm every few feet. Fine in terms of the strength of the slats, but running a block plane along the edge is a disaster. 18" of slicing through the grain followed by lifting a chunk.
To bend the slats into place, I've clamped a block to the outside of the seat supports, and reversed a few QuickClamps to make pushers out of them. An extra one vertically placed at each end keeps things from springing loose.
I've just sanded and oiled two slats so far to see how it goes, now I need a more efficient way of doing the remaining 12 for the seats, and 9 for the floor.
