OK, so the decsion was made to get rid of the upper part and hollow out the stump. But will this ever look alright? Look and see.
In the end the stump looks surprisingly 'finished' already. Much smaller technically, but it appears mcuh bigger. One great advantge is that I can now carry the whole tree alone if I try really hard. The wood of such decdiduos trees is very dense and consequently very heavy. The trunk has lost about 70 % of it's volume.
