[Harp-L] re:Repair question



Hi John,
To remove burrs I use a draw scraper on the sides of the reed supported by a thin piece
of shimstock.Burrs that are invisible can cause problems as well, and can sometimes be difficult to see. Burrs can also occur on both sides of the slot.
The rivet needs to be properly peened and secure. There is more lateral movement
on lower reeds, but if any reed is insecure problems such as movement against the slot,
tuning, buzzing, and general misbehaviour result. When pushed hard an unsecured reed will float.
Hand tools are preferable for reed work. A dremel is too powerful and can cause burrs itself.
Good luck, I hope this helps.
ATB,
Jimmy





I mostly play Special 20's and have been generally satisfied with their out-of-the-box quality. Recently, though, I've had two harps which buzz on a deep draw 2 bend. I've opened up one of the buzzing harps and checked both the draw & blow reeds on hole 2 for burrs and alignment problems. I think the buzzing is coming from the draw reed--when I stabilize the draw 2 reed and do a deep bend, allowing only the blow reed to vibrate, I get the bent note with no buzzing. Why would the draw reed on hole 2 buzz when the blow reed comes into action while bending? I used a dremel with a fine grit to burnish off any burrs on the draw reed but that didn't fix anything? Is it the rivet? Any ideas/suggestions appreciated. Thanks, John
