The gestation of a harp

    Think about the difference between raising pitch by tuning a violin string up (vibrating length stays much the same, tension increases) and raising the pitch by stopping it with a finger (vibrating length is shortened, tension remains much the same).

    One of the early steps in physics experimentation is working out very clear-headedly how to alter as few variables as possible at a time and trying to detangling all those which can be detangled.

    Bernhard, Tacye,

    I thank you both for your efforts at getting this point through to me!

    Hello to all,

    Here’s an update on the process, such as it is – I’ve cut out the inner (hard maple) and outer (walnut) ribs.

    One more comment-

    I hope the readers aren’t finding all this too boring.

    What type of wire strings are you going with? As far as I know, only three types of

    Karen,

    Thank you for your kind words of encouragement!

    I’m pretty far off from being at the point to consider which stringing material to use – My plan was for something akin to an acoustic guitar string set, with brass-wound strings in the lower registers.

    Michael,

    I found a trick for gluing… dash over to U Haul or somewhere where they sell those vacuum storage bags for clothing. One of the regular size ones works well. Then put the pieces in the bag, a fixed weight on top and hook up the shop vac!! Works splendid!!

    Liam,

    Thanks for the idea.

    Liam,

    I’ll have to experiment with this.

    Liam (or anyone else who can respond to this question),

    Entering into the world of my potentially faulty understanding of physics – is it not also the case that the vacuum technique cannot exceed approximately 15 lbs of pressure at any given point, and that its greatest advantage is in the even application of this pressure all over the work at the same time?

    Hello to all,

    Here are some pictures of where I am so far – there are multiple viewable pictures in the album.
