Luke, that is an interesting idea, but you will usually find that the
[exhauster] bellows are not only screwed to the main trunk but also
glued, and by the time you take them apart and repair any damage, you
may as well just recover your original bellows.

The covering part takes the least amount of time of the whole process,
usually.  The repairing, sealing and reconditioning the wood part takes
the greatest amount of time (well, other than refinishing metal parts).
