Chair building continues....

Our successful results with the first series of bends bolstered our confidence to continue building jigs and bending tubes.  We built a few more tools and before long we had the second part of the main element formed.

A bit of welding and we had our first completed element.

 With the tools for the main element completed, we began building the tools for the tubes that connect the two sides together.
We discovered that while similar, the tubes all had unique curvatures, necessitating a handful of new jigs. We also learned that the smaller diameter tubing and the more subtle radii enabled us to make the bends without packing them with sand.  After tack welding a few of the cross bars in place, we had a chair shaped object on the table!
