Hello made me a simple timber bench. It's about 2.3 meters. Made of spalted pine. Cut a log in half with a chainsaw then plained it smooth by hand. The legs and holes are both conical so in theory the harder you sit the harder they connect. I kinda eyeballed the legs angle so there are some variation. The construction seems weak but we shall see how long it last. The tenons for the legs are about 7 cm deep. Treated with linseed oil.
