Hello Ahmed, and the other econologists!
I bounce on your idea of log press by taking up my first comment of this same thread where I imagined a manual press with a large lever arm actuating a piston to compress a cylinder filled with wood shavings.
You then replied that the compression pressures to make these logs were such that the efficiency of a simple manual lever was highly hypothetical.
But I am stubborn! ...
What do you think of this idea of a wood chip log press: a small (very) solid case, for example the size of a shoe box, 2/3 of which constitutes a compartment that one would fill with wood chips. In the other, a metal accessory whose expansion with heat would increase the volume (a thermal cylinder), producing a strong pressure on the compartment filled with shavings; between the 2 a mobile separation.
This case, once filled would be placed on a hot spot, for example on a wood stove, which would also have the advantage of drying the chips well during compression, and the expansion of the cylinder would do the rest of the compression work! ...
It remains to find the material for the solid case (metal, reinforced refractory cement, ...), then that for the compression cylinder which must have good expansion properties. Ultimately, we can even add shims between the cylinder and the chips to make several successive compressions.
Is it playable? ...
