I ignored this fine old piece bought 35 years ago from Frog tool. Used it as-is for some log joint work, then threw it in the tool box and occasionally used it to remove glue squeeze out. Glue left on it obviously caused pitting on the inside.
Pics show what I mean.
I want to know how best to clean this up so it can be well-sharpened. As shown in the pics, what you see is the result of me taking a piece of soft wood, shaping it with a block plane to try to match the concave grind of the sweep, and then sanding with 120 grit paper.
It is going to take me a week of hand work with the sandpaper to get through the pitting.
What is a better approach?
I've a 1x30 benchtop sander-grinder, and a 3450 rpm bench grinder, and a collection of waterstones from 600 to 8000 grit, but no shaped stones for working on carving tools.
