I am readying some tools to thin out the soundbox of the harp I recently made, including a tool to get into the end grain at the top end of the harp and another to slice wood off the inside edge, Its more tricky working this way but the rewards will be a richer and more balanced instrument.
I made an extra long Olive Ash handle after the ones Robin Wood uses for my Bent blade,
This tool is used two handed and slices across the grain. Most effective on green wood!
Alongside this is another tool, a commercially available hooked knife by Mora. Still a few more tools needed to do the work I need to do. Updates in a few weeks!
