Reeds 'n Stuff Oboe Pregouger (Push Style)
The Oboe Pregouger by Reeds 'n Stuff is the push style device. Placed on a flat surface, such as a desk, it has two legs that work best at an edge with right angles, to lock onto the edge of the desk. Then place split and soaked cane, piece by piece, into the bed of the pregouger, and use the included pusher to push the cane against the blade. The cane comes out pregouged and ready for use in your gouging machine.
Another option is available by Reeds 'n Stuff for the pregouging step.
