Catproofing the harpsichord

Now that the case is complete there is one more very important task that has to be completed before I can glue the rose to the soundboard and start to string the instrument.

This harpsichord, like the historic Italian examples on which it is based, has a very light case and no lid. These instruments would typically have been placed inside a completely separate outer case for protection. I do not have an outer case, but I do need to build some kind of lid so that Isis will not be able to go to sleep on the soundboard or shred the rose into tiny pieces.

I considered several options including buying an outer case from Zuckermann (too expensive at over $3,000), building an outer case myself (too time consuming to do right now, although I might do it later), and simply attaching a lid to the case (which looks like it might just be possible but overall I don't think that the inner case is really strong enough for this). In the end I came back to one of my first ideas which was to build a lightweight lid that could sit securely on top of the instrument and easily be lifted off.

The lid itself consists of a piece of 1/8" MDF with a frame made of poplar running around the edge both to stiffen the lid and to locate it over the sides of the case. I wasn't sure when I started whether this was just going to be a temporary solution that would eventually be replaced by something else but it turned out very well so I added a few pieces of molding around the edges and this is the (almost complete) result:
