By Andrew | 8:09 AM EST, Sat December 29, 2018

Embossing tool

(New version 2021-06!) This tool is made from tempered high-carbon steel and both tips are finished by hand. The tips are carefully sharpened to the correct specification to allow it to emboss the slot effectively without shredding or otherwise damaging the slot. I ensure that each tip is perfect.

The Flatness Tool™ and Reed Plate Claws™

By Andrew | 12:04 PM EST, Sat December 30, 2017

Use these tools to flatten the comb and reed plates.

Straight, flat reed plates fitted to a flat comb are the best framework for the reeds. Even a thousandth of an inch of space between the comb and reed plate means the reed will be less efficient at converting air flow into decibels.

Shim Stock (three pieces)

By Andrew | 12:51 PM EDT, Sun July 16, 2017

Shim stock is very useful to have on hand. Use it to de-burr after over-embossing or for measuring air leaks.

I tried sheets of tempered shim stock but ran into trouble. I can't cut small pieces easily without crumpling the edges and that defeats the purpose!

Grobet Tuning File

By Andrew | 8:25 PM EDT, Sat May 20, 2017

Grobet USA, Made in Italy, Swiss pattern file.

0-Cut is right on the margin between coarse and fine. It's perfect for removing brass with a light touch. It's coarse enough to have power but doesn't leave scratches and tracks on the reed.

Warding shape: Like a flat triangle with teeth on every side.

Raise or lower the pitch of a reed with the reed plate on or off the comb.

This file works on Brass, Stainless Steel and Phosphor Bronze reeds.
