I thought this might interest some of those guys out there who are into doing some veneer work
This one is Walnut with Pear wood. With the High Gloss finish.
This kind of work is special and a bit tricky because the border pieces of veneer and the inside (four rectangles) are bookmatched at 45° and the inside and outside are matched so that they line up at the corners. One wrong cut and its sort of ruined, because all the pieces are behind one another in the stack of veneer and its difficult to get another piece to match just like the original one. Still would look good, but just not 100% perfect.
I have a special tool that I made as an apprentice to cut the strips of pear wood that seperate the walnut… Its basically a block of beech with a “mortised out” square on the side/bottom that had two nails pounded in. The nails line up with razor blades that I can put in with small plexi-glass pieces that fit inside this mortise, and serve as distance holders for the razor blades, I use a guide wood to keep the strips of wood straight when I cut them.
When sanding such pieces of work (with different directions of veneer or solid wood) its important to keep in mind the direction of grain. Such things one can only really sand by hand with patience and practice…. did I mention patience?
The other special thing with this sample work is the finish. Its High Gloss 2 component varnish. After sanding, the wood is then filled in with filling varnish, then sanded then filled again, then sanded, then varnished with the High Gloss, sanded again (always finer as the coats of varnish build up). The last two coats are sprayed “wet in wet”; sprayed, let set for a 15 min then sprayed again, to speed up the processs a bit. The High gloss is then left for a few days 4 -5 to harden out. Then its sanded with 1500 grit wet, then polished with first the mittel fine wet polish paste (grit unknown) then with the fine metal – machine polish paste (from 3M the one with the blue tip)
I have been told that with high gloss finishes, the human eye can identify and pick out small imperfections that are around 1/1000 th of a millimeter (about 1/100th of a piece of paper)! Especially when there is a light source such as daylight.
