When I stripped the drum, the shell was in upside down, so the snare bed was against the batter head. The snare bed is simply a section of the bearing edge that is cut away so that that section of the head is lower than the rest. This enables the snares to lie flat against the head.
At the top of the diagram above, is an enlargement in cross section view, showing how the head is wrapped all the way around the flesh hoop. It also shows the direction of force applied to the flesh hoop by the head: the head is pulling the flesh hoop in towards the centre of the drum, and because of the lapping the force is also pulling the outside edge upwards, thus twisting the flesh hoop. The problem with wooden counter hoops is that this force exceeds the strength of the wood, and does bend them out of shape; being hygroscopic they then “set” in this new shape and become conical.
After the heads had dried, I made new gut snare snares.
These jobs are always pleasing, but there are few times that I am really tempted to keep the instrument – it sounds incredible, so earthy!
