Ash picture frames from a log

This is the starting material, a spalted log of partly air dried ash wood.

The log was split in half and then sections of the desired thickness cleaved off.

 Notice in the photo that this log had a well defined curved grain that would be followed when making the frame. The next step was to cleave one of the slices into about 3 cm widths so that each "slice" gave four pieces needed for the frame. I then selected the pieces for the uprights and top/bottom rails. and cut them to the approximate length and selected what would be the reference faces. These were prepared with a roughing or scrub plane first (using a straight edge to decide where to remove wood) and then a joining plane to get a flat surface. The second reference (the narrower of the two) was then planed with a spokeshave at right angles to the first. After this the dimensions were decided and marked from the reference faces with a gauge and then planed to size, finishing with the joining plane on the flat surface and spokeshave on the curved.

The frame was drawn on a piece of A4 paper so that the picture sat squarely and had a border of about 8 mm (for my pictures this was 210 by 140 mm). The pieces of the frame were then aligned with the drawing, made symmetrical as needed, and then the first cross-lap joint on the top was marked with a fine pencil. This was cut with a fine toothed tenon saw keeping to the waste side of the line and the wood removed by a chiselling and finishing with a miniature router (Veritas). The joint was then finely adjusted by chisel to get a tight fit.  When all four joints had been cut, they were fitted and the second half of the joint marked with a marking knife and then chiselled to get a close fit. The frames were sanded and treated twice with Danish oil to finish them.
