The Jeanne Gouging Machine is a "double radius" machine, which produces increased stability in the reed. It is designed for the oboist who wants to have complete control over his or her reeds, with the ability to personalize the gouge in order to achieve the desired qualities of timbre, response, pitch stability and tip opening. The Jeanne gouging machines were designed by Valarie Anderson, in consultation with John Mack, in 1992. The Jeanne gouging machines are built so that everything can be adjusted, allowing for the greatest flexibility. This makes the machines more expensive to manufacture as any engineer or machinist will tell you. But our gouging machines, like our shaper tips, are available only through direct sales from Jeanne Inc., giving a higher value at a lower market price.
The shape of the guide is critical to achieving the desired end results. The guide on the Jeanne machines has a modified curvature of 12 mm with a slight incline from the blade, allowing the guide to hit the cane directly in front of the blade. Our machines have a minimal space between the guide and the blade to eliminate tearing problems. An eccentric bearings built into the carriage controls the manner in which the guide hits the cane.
The carriage of our machine rides on special linear motion ball bearings which in turn are fitted into the carriage eccentric bearing. It's the unique ball bearings that give our machine such a silky smooth action. The carriage of the machine needs to be level; otherwise, the cane can be pushed to the side of the bed creating an uneven gouge. We put eccentrics in the posts of the Jeanne machines which can be used to raise or
lower the carriage rod.
The blade has both a depth adjustment to control the amount of cane removed with each swipe; and a side to side adjustments, which controls the rate of fall-off from the center to the sides of the gouge. The side measurements of the gouge can also be controlled by moving the bed. Both methods are necessary as the results are completely different. The gouge thickness is controlled with a simple set of parallel bars. There's a compartment built into the bottom of the base that stores a special wrench that's used to make these adjustments.
We have created a manual with full-color images and detailed explanations of each aspect of the assembly and setup of our gouging machine including sharpening the blade. This manual is for reference only and any adjustments to a gouging machine should not be undertaken without a thorough understanding of the machine parts and their relationship to the gouge.
