Carving for smooth healing?

(1/4) > >>

Sorce:
One, Does anyone use carving on a wound intended to callous over?

If so, do you switch bits to keep them cool, so they don't cook the live tissue?

And, Direction? Do you grind the tissue edge towards the wound or away from the wound?

Meaning, is the bit sweeping the edge in or out. 

Direction makes a huge difference, just wondering if anyone has mastered this.

0soyoung:
I don't think it matters with 'slanting' a chop, but if your tool tends to tear the bark from the bole, go the other way so that the rotation of the bit is inward, toward the center of the cut or use a different bit. I use 'structured tooth' carbide bits in a Dremmel tool that make a fairly smooth cut. If I've erred and made a ragged edge, I finish by making a clean cut of the exposed cambium with a grafting knife. In the case of dieback of a branch, though, I try not to damage the branch collar other than incidental knicking of the inner ring. Again, accidents can and do happen and I just clean up the ragged edge with a grafting knife in the end.

Sorce:
Thanks Oso.

scottroxburgh:
I've only ever used hand tools, knob cutters, small chisels, and a grafting knife.

I too would be interested in what others use.

Gaffer:
Gota use a Dremel. They have bits that cut very clean. When you recut the Claus make sure your first cut is lower and when you cut the callus keep it low to the callus. Does that make sense.
Good luck
