To achieve the stream chairs uniformity I assemble its several parts in a universal positioning device. The concruence of the chairs is provided by a grid, and in abstract terms this grid is the least common constructive denominator of the chairs. In the trestle you can see on the picture all parts that have identical positions in all different stream chairs are positioned. To facilitate my welding I clamp all parts to achieve tight fits and perfect seems.
