Glad to hear you are going to bring out a pro to access things - usually no charge for an estimate, but that may have changed since the '60's, (that's 1960s, not 1860s):laughing:
One close call is usually more than enough to make folks not want to chance another one. And as a rule of thumb, if you think you might want the help or opinion of a pro then you need to follow the instinct, IMHO.
Personal experience: was working with a Vietnam Vet who was several years older than me. When he pulled the saw away from the tree I was helping to push on to try to make sure it went in a certain direction the chain cut through my jeans just above my knee, but did not catch any skin- fortunately. Needless to say I was pissed and refused to work anywhere near him from then on. BTW, he was not a bad guy, just too careless for me to work around for my own sense of self preservation.:confused2:
