thanks all... I'm pretty bushed at the moment, so just a quick reply tonight... more after I grab some sleep...
I forget where I saw the tree motif, but it must have been in one of the mags' plans... suspecting PopWood .... simple as can be, I just marked 1.5", 1.25 etc... and mirrored the cuts on the bandsaw. Looking at the slats, I think I mixed up two stacks (I cut enough for two chairs) so I will at Least pull those off (all but the center two) and line them up in proper order... but more likely I'll simply cut some wider pieces, I have 5 or 6 more 2x6x10' PT boards on hand.
Roger, my plan is to let these dry a few weeks or more, then put on a primer layer, and a good coat of latex in a deep forest green or two over that.
oh, Paul, check out Jake's chair... taller and slightly wider adirondack style chair, but one which doesn't make you feel like you need a sky hook to get in or out of them.
