1. Remove the original case feet by drilling through the rivets.
The existing mounting holes of the original feet can usually be reused.
2. Determining the position of the stabilizing feet
Find out the proper orientation of the each stabilizing foot. The inner side (facing the case shell) is slightly slanted.
For each foot, choose the mounting position in which it is less inclined outwards. Place each foot individually and turn it in the correct direction.
3. Define the position for the drill holes
Before drilling, mark the position of the existing mounting hole on the foot.
4. Drill the holes
Drill the rivet holes in the stabilizing feet: follow your mark for the bottom rivet, choose an appropriate position for the second rivet.
Drill holes in the cello case: Fix each foot first with a loosely inserted rivet in the shell, use the foot as a template to drill the second hole in the case shell
5. Rivet the stabilizing feet
Mount the feet with the supplied rivets and washers.
6. Fine adjustment of the stabilizing feet
Place the cello case on a perfectly flat surface (e.g. table top) and check for tilt. The length of each foot can be adjusted individually using a cutter knife or a planer rasp. All four feet should have even contact with the surface.
