I finished this tree seat about a month ago and have just got back to take some pics.
The client wanted a thick chunky look with no gaps in the seat surface as well as having it sit on stone balls. I originally quoted for a complete ring to encircle the trunk (4ft dia oak) but once she had got back up off the floor the design was revised to a semi-circle :wink:
Its all done with 75mm thick iroko which I had South London Hardwoods thickness only, (no need for edges to be planed as they would all be cut). Luckily they all came in at 2.1m lengths as at anything longer the 400-450 wide slabs would have been a bit heavy.
The main seat is made from 12 segments and two semi-circle ends, overall diameter is 2550 with the inside at 1350, giving a wide 600mm seating surface. The segments are joined with a pair of 40mm wide loose tounges made from 6mm birch ply and all stuck together with West Systems epoxy. It made it in 3 sections which were then glued & bolted up on site before sanding the joints and touching up the oil finish.
The sub-base is again 75mm thick but in 5 segments with the grain running around the circle rather than tangentally like the seat. There are 3 recesses to locate it on the balls which were drilled and then had resin anchors bonded in to bolt them to the subbase.
The balls themselves are 400mm dia solid sandstone and weigh about 80kg each, so it wont be going anywhere.

- appeals to both my artistic and practical criteria.
