1: Suitable blocks or “chunks” of a hard-type wood were obtained – and in this case blocks from an old apple tree from Southern Finland were used.
2: The rough blocks are cut into thick oblong right-angled shapes [the actual size depends on the measurements across the frame-support and the diameter of the actual shaft] and planed smooth and square on all 4 sides and both ends.
3: Carefully draw a pencil-line around the block – around and through the exact middle of both sides and ends, then do the same down and along the top and bottom. Two vertical holes are drilled on this upper pencil line from the top down right through to the bottom at a suitable distance from each end so that the finished bearing can be bolted to the frame assembly when required.
