I don't know if I need to work with higher grain, what do you think about it ?
I'm actually waiting my wood filler ! ^^

For the moment, my impressions are that I love to do this, I always love the wood contact, but here, just to make this wood piece become so smooth ! Ahah
I already work with wood, but it was as a scout for living construction (table, boat, bivouac over the water, trapper's hut to spot animals...). It was therefore only the rough work of the saw, the chisel, the mallet, the burrow, etc ... The accuracy of this work, which is still at its beginning, I already like very much !
