I am sweating bullets on this thing! It is about 3 1/2” in diameter and 3” tall with an entry hole of 3/4”.
I am about halfway done with the hollowing and the finished part has walls of about 1/8” However, the tool is starting to get a bit jumpy and grabby.
As this is a sugar maple burl from a farm that has been in our family for well over 100 years the wood has a lot of sentimental value. As a result I DO NOT want to blow it. Figured I would step away from it for a while before doing something stupid. :-)
