With the new, simplified trolley built in part one and away being painted, I turned my attentions to repairing the note bed of this Premier Xylophone. Obviously it is a good excuse to get out my longest clamps!


What I didn’t say in the video is that the pegs were originally glued in with a clear silicon. I have seen this technique used before, and really don’t understand why. If you have used it to seal around window panes, bath panels, or the kitchen sink, you will understand that the real reasons are that it is really cheap, comes in a well designed tube so that it can get into awkward corners and stays wet in that tube for a long time. This is useful in a factory, it means that the lid can be left off overnight without the glue spoiling.

However what I don’t understand, and maybe I need to mull it over more, is why silicon sealant would be used to secure a structural joint. Surely the very same attributes that make it perfect for bathrooms – water-resistant, flexible, gap filling and slow cure, make it the worst choice for musical instrument manufacture, furthermore it will absorb vibrations and deaden resonance. Did I mention that it is gap filling and you can leave the lid off overnight?

The problem for me of course is that I have to remove all the silicon goo because nothing else will stick to it.

I do use synthetic glues, they are great in the right place, easy to use, easy to clean off the excess, good shelf life, etc. But more and more I choose to use animal glue, after all it has all the same attributes whilst using it and it is exceptionally strong. It is not water-resistant, but that means it is easy to un-glue something, so for me the only down side is that it takes longer to use. Even then it only takes longer if you forget to warm it up before you need it and have to wait; what a disaster you have to make a cup of tea.
