Inboard: top cut is further in than bottom cut .

 

Outboard: top cut is outside the bottom cut.

 

Learn it, pass, forget it.

Been a while since my 39 but this is what i remember it to be:

With regards to "step" cuts, place the undercut in first then with an outboard cut place the top cut further out than the undercut. With an inboard cut the top cut is closer to you than the undercut.

The difference in effect of the cuts are, if you are letting the branch drop, an outboard should drop flatter (if cut right), an inboard should let the branch drop tip first.

If you are cutting then holding the section it will help whether you want to snap it off downwards, upwards or sideways if placing the cuts at the side of the branch.

 

Hope this helps - good luck.

Many thanks guys i think i understand it alot clearer now. Under cut 1st, then either cut above for outboard or below it for inboard

Step cuts....

 

Freefall cut: undercut first then top cut either towards the trunk (inboard) or towards the tips (outboard)

 

Handheld cut: top cut first then bottom cut towards the tip (or side to side as already stated.

 

Should you learn and then forget how to do a proper handheld step cut, you risk spending the rest of your tree cutting career looking a bit of a dweeb :-)

Naaaaaah, I didn't mean forgetting how to do it for the assessment, I meant that many people pass the assessment by doing it all good, and then forgetting the theory and doing it 'wrong' forever more!

With a freefall cut, the wood you are cutting is probably heavy, so you cut into the compression wood first and then the tension wood (you don't want to trap your saw).

 

With a handheld cut, It does't matter if your saw gets pinched as it is only a bit of light, manageable timber.

 

In fact, with a freefall cut, it is an advantage to get the saw 'pinched' in the undercut, as this shows you have cut enough - this is why you cut into the compression wood last.

 

Piece of cake. :-)

Take your time and enjoy it.

 

It is soooo much easier than getting your basic felling ticket (as long as you get really good work positions).
