Then these were copied on sketch paper and mounted on ¼" MDF. Each chair part or component was cut out and a template was made.
This way the chair can be made and repeated with great consistency. Construction The templates are then laid on the 8/4 poplar plank that is being used for the prototype. The chair part templates can be moved around to economize and reduce waste.
The 12’ plank is jig sawed into smaller sections and the curved parts are bandsawed 1/16” over the line. The straight parts like stretchers are cut on the tablesaw.
I carefully designed the side stretchers to meet the front leg and the rear leg at a 90 degree angle. The curved rear line merges with the “flat” intersection and it is not noticeable that is square. This allows the side stretchers to be simple rectangles and simplifies the joinery.
The front and rear leg to stretcher intersections are also 90 degrees.
This would not be the case if the chair sides were splayed and not parallel . I have made a lot of chairs like that and you just need to take the angles right off the full size drawing.
