The design for these Doug Fir brackets required an Ogee profile applied at the base of each leg against the wall. The PDF drawing was loaded into TurbeCAD and adjusted to scale using a given dimension. Then all necessary dimensions that weren’t given were determined. The profiles for each element that would need to be cut out were traced with be a combination of lines and bezier curves at true scale. These patterns were then printed on paper, cut out and traced onto plywood.

When the plywood patterns are cleaned up and sanded they are clamped on the finished Fir pieces and a 3/4″ Amana router bit with a top bearing is used to transfer the pattern. Then an Amana router bit with a bottom bearing is used from the opposite side of the piece to complete the shape. The combined cutting depth of the two router bits was not enough for some of the profiles and a second pass with the top bearing was needed.

This sequence can end up being a lot of information to collect, organize and communicate to the folks doing the work the next time. Grainchek will be a platform that can be used for documenting processes in a way that can be edited, stored and shared.
