The F Tool™

By Andrew | 6:43 AM EDT, Fri June 05, 2015



***Please note I am no longer offering this tool. I have a new tool set which takes its place. Please see The Flatness Tool™ and Reed Plate Claws™***

The F tool™ can find and correct air leaks caused by a reed plate that is not perfectly flat.

Use it on Both the blow plate and the draw plate.

How to use the F Tool
These instructions use the French Tuner to measure flatness instead of the reference bar. The newest version of the F-Tool includes its own reference bar. Use it in the same way.

This tool includes shim stock.
