Same picture, same drums, but this time I am doing the work on them.

When I overhaul a set of timpani, there is a lot of work involved over a period of days or even weeks. My approach is to fix everything properly; I am after all a professional and that is what I am being paid to do. So I am fixing problems associated with the usual wear and tear, as well as “the dogs dinner” that the previous person made of the job. The posts on timpani pick out examples of problems I encounter, rather than me filming and writing, and you watching and reading the same thing every time. For the same reasons I have coloured this introductory text blue (aren’t I thoughtful!)


Commonly timpani use three points of contact with the floor (so they don’t wobble), with two wheels at the back and the pedal at the front, with the aluminium casting under the pedal sitting on the floor. As the drums are moved around, the aluminium foot at the front suffers from abrasion until they are completely worn away. This is a problem that I often have to resolve, but the biggest “problem” is reversing the shit solutions that other people have created to repair them! So in this case the “dogs dinner” was how the toes were repaired. Whatever the pads or heel blocks were made of was not the problem, it is those damn screws that were used to fix them in place.

As can be seen below, my ingenious solution of simply welding another bit of aluminium on even looks like it will last, especially in this raw state.

The source of the problem is that aluminium is so soft. It is also lightweight which is why most timpani chassis are made using aluminium castings. On a practical note it is a horrible material to work with, clogging up all my saw blades, files and abrasives like treacle tart. But because it is so soft and wears away maybe it isn’t the best material to use as a wear point. It is all about instrument design again – or the lack of it.
