Flatness Tool with Reedplate Claws and Holder

Developed by Andrew Zajac.

The fundamental improvements you can make to a harp are to make each piece fit together perfectly for an airtight seal. This is one of the most straightforward things you can do to make a harp play better. Use these tools to flatten the comb and reed plates.

The Flatness Tool™ is used to measure flatness. It is an extremely precise straight edge reference. It has a reed groove so that it can be used on both reed plates as well as the comb. One you find where the comb or the reed plate is not flat, you can correct it. The Flatness Tool™ can also be used to make combs extremely flat.

Use the Reed Plate Claws™ on both the blow and draw reed plates. On the blow plate, the reeds get in the way of flat sanding so all you need to do is straighten them using pressure and counter pressure.

The Reed Plate Claws™ are designed to fit safely between the reeds.

The Reed Plate Holder will help you hold the reed plate steady as you straighten it with the Reed Plate Claws. Once you get comfortable with the claws, you may no longer need the Reed Plate Holder.

It has two slots to accommodate many different sizes of reed plates. Use the smallest
slot that fits.

The Reed Plate Holder ships with a sticker on the under side. The adhesive will help hold the plate in place. Once it loses its stickiness, you can peel it off and replace it with any kind of tape you have on hand. If you no longer need the additional help from the adhesive, don’t bother replacing it.
