This case (to suit the dimensions of my
5 string alumunium violin/viola) is easily
made, commencing with a single sheet of 1.6mm gauge aluminium measuring
1200mm x 710mm and cut into two identical size sheets measuring 475mm on the
wide end and 235mm on the narrow end, allowing ample left over material if
using aluminium for the ends and partitions. The long axis has a bend of approx. 10 degrees along the centre to both stiffen the case and allow extra height above the bridge, giving a depth of 30mm from horizontal at the wide end and 8mm at the narrow end, with 70mm along the sides bent up 90 degrees from the horizontal. This shape allow the instrument to be precisely centered with nominated equal distances between the instrument and sides of the case to allow for padding. It also allows for precise alignment of the top, either for edge to edge closing or overlap closing. The ends and partitioning can be either aluminium or materials of choice, in this case I have used pine wood for simplicity. The design criteria was for a case that could be rested on its bottom, side and end (for vertical storage), has a lid that when closed automatically holds all the compartment lids closed, as well as holding the instrument firmly in position, with no chance of it lolling around inside the case with the bridge and strings rubbing against the lid when being carried, that cheap cases allow. It's not a light case but the weight could be reduced considerably if aluminium was used for the ends and partitions. |
