Saw cutting squint

[drinksloe]

Alright

 

Just wondering various causes of saws cutting like a banana!??

 

Now I realise most are chain bar related ( cutters or rakers unequal, poor bar maitanence etc)

 

S there much else can effect it?

 

I should say this saws never really been right since it got rumbled about about by harvester.

I had it behind a tree in a small ditch, knew it was within tree length but had so much gear to shift about and under presure, and not a lot of tree to fell. 

Thought it would be ok. 

 

Tree never hit it full on but the branches must have picked it up and dragged it under it as it was moved back and forward as it was processed.

Plastic chain brake, air filter cover, bar side cover and various bits of plastic slightly broken, bent slightly bent.

Think aluminium handle slightly bent too.

But saw seems to run ok apart from cutting squint.

 

Just put a new bar and chain on but I have to admit that new chains had a battering since ( which is not like me, usually look after them)

So it's not helped as much as I hoped and not cured the problem .

 

Just gave the chain a good going over and think got it right now so will see tomorrow.

Burt could it be the wrap round handle being slightly bent??

The rails being worn uneven so the chain cants over and the rails being splayed so the chain flops to one side are two very common issues!

I can't think of anything that's not bar or chain, unless sprocket is also knackered so the new chain is immediately battered. See recent threads by RobD.

Av mount damaged?

Cheers folks..

I'm on a new bar so will have a go with that battered chain if not I do have a spare new chain.

So hopefully tomorrow and really concentrating on  my cuts can try to minimise operator error.

Nothing worse than putting a new chain on and spending a few days cutting high stumps down, 1 compartment after been mounded.

 

It does seem worse doing back cuts, when u want things square than when converting produce.

So possibly handle/AV

 

It is a relatively new 372 so do have an old saw that still runs as back up and some knackered donor saws.

Might have to swap handle out.

 

I have to admit never looked that closely at sprocket yet. Didnae really think it would affect it

The damage to saw was more rolling back and forward than getting squashed.

 

Cheers again.

Out of interest do you have 2 spikes on it ?  Saws do tend to creep in oversize felling cuts with only 1 spike , particularly on backhand.

Do u know wot u could be on to something there.

 

Never had it out today, ended up smaller timber althou a few  on the right limit for my 15" bar, boring gubs etc and was great to have cuts meeting almost effortlessly.

Not too much operator error today, for a change.

Got 6 or so big 1s to do the Morro thou, so will see how see goes.

 

Cheers will look into an extra spike.

Take it no drawbacks to having 2 sets on?

I have double dawgs/sdpikes on my big saws but not on the smaller ones ( 60cc downwards )  as I find it makes snedding/de limbing less efficient .

[drinksloe]

Got double on my 660 but never sned with it, in fact it rarely comes out to play.

Good point thou stubby as do tend to sned big hairy 1s out with the 72, so mibbee not worth it.
