English Rogers - Shells
The English Rogers catalogues give the following description of how the shells were made :-
|By far the most common ER shell is made of 3 ply birch plywood which is bent into a cylinder with an overlap to form a scarf joint and has laminated birch glued reinforcement rings. Eddie has refered to this as an “Edgware shell”. The grain direction of the inner most and outer most plies runs from bearing edge to bearing edge rather than around the drum. The inside of the shell is lightly lacquered.|
|However there are variations. Beech was occasionally used instead of birch especially it would seem for snare drums and 13x9 and 14x14 tom toms but could be used for a whole kit.|
|Rerings were occasionally solid beech or of 3 thick beech plies and occasionally the rerings are nailed as well as glued. Eddie refered to this as an “Ajax shell”. These variations occurred right up until the end of production and probably just reflected availability of materials at the time.|
The bearing edges on the early shells were simply rounded over in common with many drums of the time, including their contemporary Rogers USA cousins.
|However by 1962 Ajax were spindling their edges with a sharper Powertone-like bearing edge. This consisted of a 45 degree internal chamfer and a small radius externally. However this too was subject to variation, and some of the drums were still sold with the rounded over edge. From approx. 1965 the internal chamfer angle reduced to approx. 30 degrees.|
