Errr, Geee, Hmmmm
I'm a little worried about you there mate. Some of those questions, errr, bit scary, do you cut a notch etc?
Palms aren't like normal wood and they do some wierd ****.
Make sure you got relief cuts in.
Notches do a few things, they provide direction for the felled piece and a hinge. All equates to control. In this video they were all notched, I just edit that bit out coz it's pretty boring and pretty much std stuff ... so all you see is the back cut.
I think for starters you should watch some vids, I rec these.
Foam trilogy series ... I dont lower palms (extremely rare for me)
Draw .... hook and bungee lanyard so no losing your saw
1/4 cut for Jedi's ... shows wing cuts, or relief cuts, or fibre cuts or whatever people call them.
Hey, be careful, how long you been doing tree work?
