Curves at last !
The method of slicing a board into many narrow pieces and then using a cloth as a backplane hinge turned out to be a complete success !
There seems to be a very good option for the “cloth” that is supposed to be used for the back-side reinforcement of the individual wood slices. After some shopping around, or hunting around within the drapes and curtains department, I finally came up to a stand where they have these hemming tapes, so as to reinforce and balast the very bottom of every drape or heavy curtain.
These tapes are made of poliester, a very sturdy and rigid material. It shall withstand a fair amount of abuse, whilst getting the final “shape” of the curve right. The tape is 10cm wide, so it fits nicely as two runs within the 20 cm height of the slices.
The glueing is a straightforward activity. After sorting out the puzzle and assembling the wood pieces in EXACTLY THE SAME sequence, as they were within the uncut board, you simply align them, double check for right angles, pre-fasten the whole length with a carpenters clutch (the one with “pump to fasten” mechanism), along the span of all the slices.
Then re-align each and every piece of slice again, triple check the straight angles and smooth boarder line, and fasten / tighten the carpenters clutch securely. Then simply lavishly pour some wood glue (I use VIKOL) on top of the surface, spread it so that it covers the whole area of the “board”, and put appropriate lengths of the poliester tape on top of this. Soak it in. Press it in to the glue with a piece of wood with a smooth edge. Let it soak full within the glue. Distribute the soaken glue from the outside of the tape. Repeat a few times, whilst the surface is drying.
Each time using gentler strokes. Then simply leave it off for the night, so that it dries off thoroughly. No rush. No hurry.
All good things take time.
P.S. Till now, I still have yet to take a saw into my hand. I still did not use but a single cutting or drilling tool. All cutting work, within the straight angular cuts regime, originates from the wood services department of Leroy Merlin.
There is NO CHANCE that you shall obtain such a regime of even and orderly edge, if you try to do it with some non professional, haphazard tooling, stored in the shed of your back yard. Unless, of course, you are equipped with some really specialized equipment, an orderly workbench, all machines stationary, installed, and ready to use.
An even, straight angle of the wood slice edges is critical. If you do not get them right and even, then the whole concept of the “hinge” … will simply not work properly.
