Hello harp players,
On 3/21/94 at 14:44:37 -0500 (EST) Peter McGuire said in part
"The comb is made of wood, and when I use the harp for any extended period of time the moisture from my mouth causes the teeth of the comb to expand. They expand a few millimeters beyond the cover plates, interfering with my lips something terrible."
Well, it's been a long time since I've really played a marine band long enough for this to be a problem but I do remember sanding down the comb on a couple of harps long ago. Other folks have suggested this already but I wanted to make this point...it's the edges of the wood sticking out that are ripping up your lips. So instead of sanding the expanded wood down flat to the harp, just sand the exposed edges of the wood, to round off the sharp edges. This should reduce the damage to your lips and still preserve the integrity of the seal between holes when the harp is dry.
This solution is an imperfect one as any sanding you do to the comb will remove the coating, thus allowing the wood to absorb water even faster than before. You might want to take the harp apart (after sanding the edges round) and use something like gun-stock oil to recoat the wood. after each coating of the oil use a steel wool pad (or kitchen scrubber like Scotch -brite or something) to smooth out the coating and give it a finish that dosen't feel sticky but that your lips can slide over easily (sort of a satin finish). I would say try two or three coats of the oil, steel wooling CAREFULLY after each coat (the wood comb IS fragile and can easily be broken) to provide a good seal against moisture.
Of course now I play Golden Melodies so I don't have this problem...
