This is déjà vu. Actually I have done it deliberately; sometimes it is nice to work on two identical instruments side by side. However, the job that I have to do is completely different to the other Premier xylophone that I am working on (Job no: 1281). For a start this instrument is almost in one piece!
Unlike the xylophone in Job no: 1281, this instrument lives in cases and is frequently taken out for performances, so portability are versatility are important features that I have to retain in my design solution.
There is often a compromise between weight and strength especially when there is a budget. Unfortunately I do not have the resources or facilities of a Formula One team or Nasa, and I think that most customers would not really want to pay for composite or titanium frames. Aluminium is the option that most manufactures are taking (ignoramacies!). In my view this is the wrong direction; it is like using chocolate to make a tea-pot! Better design is the answer, and accept the fact that percussion instruments are heavy, after all, they are massive. If you want to buy a lightweight aluminium frame that can be carried, then carry it! Don’t put casters on it so that it can be wheeled around. Furthermore, when the aluminium breaks, it is harder to repair. I send aluminium out to be welded; I already spend around £500 a year on renting the bottles of gas I regularly use without needing another one specifically to weld aluminium occasionally.
So I use steel. Steel is strong, steel is cheap, it is easy to work, easy to finish, easy to repair. Steel has a lot of benefits over aluminium, the one downside is that it is heavier. But let’s get our facts right, if I were to hold two bits of tube, one steel, one aluminium, of equal length and equal strength I think that difference between the two would be negligible. Anyway, that’s something for me to find out.
Despite all that, Premier use steel, so that is what I have used to modify this frame. I have also beefed up the design so that the frame is a lot stronger. At the end of the day, it has been given to me because it is broken – the original design failed. Inevitably this means it has put on weight, but I have spent a lot of thought on how to limit it.
