Newbie Question - rocking the saw...

[Chris Sheppard]

Seems a very common technique on youtube vids

 

But we all know Youtube doesn't mean it's rght though

 

Using the spikes on bigger stuff is naturally going to produce a rocking action of sorts, but I can't really think when I'd be doing a similar action without the spikes. It almost sounds a bit like you were "landscapering", which does make it look hard work

 

A well sharpened chain will pull the saw into the wood without needing to be forced (hence why on the whole it's those who use saws less frequently who tend to make t look hard work)

That's the key point with rocking.

 

The bar is straight, so the cutting face is straight. If you keep the saw straight without rocking, i.e. just pivot it around the dogs into the wood then you are making a fan shaped cut, so all teeth are cutting at once and you're using the whole bar (admittedly the back end of the bar is travelling less distance in its arc, so does less work, but it's still a reasonable approximation).

 

If the teeth are dull then they don't 'bite' and tend to skid. Similarly if the saw is underpowered for its bar length then it stops it from bogging down. These effects are reduced if fewer teeth are in contact with the wood. Rocking the saw creates a curved cut, so only a few teeth are in contact at any one time.

 

It is, however, more effective to just sharpen the chain or not buy an overly ambitious length bar
