Vcarving wooddough

hello folks,
I am carving a LARGE Project!
Over 6 feet.
The problem is that there is a knot in the middle of the wood where I need to do a vcarve.
When I first went over it, the vbit shredded parts of the knot area.
I have made a mix of titebond III and sawdust, and filled the area back in.
I am going to allow it to dry for 24 hours, then try to carve it again.
I am wondering what settings to use for a sawdust/glue mix?
Any suggestions would be greatly appreciated.
Thank you in advance.
Martin
