PREPARING ROSETTE ELEMENTS

PART 4 - THE BORDER ELEMENTS.

Same old, same old. Not much to report really.

The border log was made from 5 sheets of veneer; Rosewood, bubinga, maple, bubinga and rosewood, cut to size, 1¼"x8", with a Stanley knife and a metal ruler clamped with a MDF caul, using many strokes to avoid splitting and other mishaps and glued together using cut-to-size MDF cauls and wax paper and left overnight.

It's a little tricky to keep the veneers from sliding around in the wet glue as clamping pressure is added. My approach was to add very light pressure in one end while trying to keep the veneers aligned with my fingers. This was repeated at the other end. Then little pressure was added to the first clamp again, then the second one again, all while keeping the veneers in place with my fingers. The two middle clamps were fastened in the same manner and all four clamps were slowly tightened. The trick is to squeeze out all the excess glue while keeping the veneers in place. Once the that is done the remaining glue will start to grip and veneers will be locked in place.

After the glue had dried I sliced the sandwich up
into 6 even little logs on the bandsaw, turned them 90º around their own axis so they laid facing top against bottom, glued them together and left them overnight. For this last gluing I used 1/8" thin cauls wrapped in cellotape for the sides and a caul to hold the segments down with a massive Bessey clamp, tightened very lightly. Wax paper was used on the top and bottom to keep the whole setup from gluing together.

Last both faces were planed smooth to a final thickness of about 3mm (1/8") using my taper jig and cut into 1.2mm (3/64") strips with a fine dovetail saw.

The border veneer rings were cut with a Stanley knife too as described above
