Hi all. Thanks for your supportive comments. I'll try to answer the questions asked. The segments are cut clean from the start. I use a Dewalt compound mitre saw to cut the segments, and then just lightly sand the edges to remove any slivers. If possible I gang cut pieces as this helps eliminate the slivers. The thin wenge segments in this piece were cut this way. When assembling, the adhesive ( 5 minute PVA) is applied as a thin strip along the appropriate edges using an artists fine brush, thus very little sqeeze if any is seen when the segment is pushed into place. If there is excess sqeeze out, this is removed with a damp cotton bud or pipe cleaner, but I rarely have to do this. The completed piece is cut using a half inch or three quarter inch bowl gouge. After sanding, I vacuum the whole to remove the dust and then wipe with a tack cloth before spray acrylic lacquer is applied in a few coats. The key to all this is only put the adhesive where it is needed and not too much, and clean uo the dust as you go. With a good blade and fast blade speed, no edge sanding is usually needed.
There are only three woods used as stated. If you see what you think is another, it is probably down to my picture taking or camera illusion. Hope this helps and thanks again for your comments. Malcolm.
