It was a surprise for me as well, when I saw the result. I accompanied the work until the prime coat. The artwork was made by the kids autonomously.
In the raw wooden state two of the cajones with conical cut surface sound better than the other two. The biggest (ca. 38-40 cm diameter) has a very full bass tone and it is really inspiring to play on it. The next (32 cm diameter) did not have the same quality but became better after been painted. The one with 29 cm diameter is excellent and the smallest (26 cm diameter) does not sound fully - in my plans it should be only 28 cm high but the carpenter ignored it and made the pieces of same height than the others (ca. 68 cm).
The corpus of the bigger box-cajon is made of poplar (12mm). This makes it rather loud. But the sound-hole in the bottom seems not to be optimal. The backside is birch (6,5mm), glued completely onto the corpus, the frontside is also birch, but only 4mm and screwed.
The smaller box-cajon was just a try and had originally two beating sides. It should have been played sideways while lying on the thighs. But finally sombody built some skids "under it" (= on the better side). The corpus is from 9mm birch plywood. The beating sides are from birch - one 4mm and one 3mm (which sounded better).

No snares inside. For this we use normal afro-peruvian styled cajones.
