Bar wear

Hello,

 Not having much luck with bars recently.

Worn out 3 different makes of 60cm bars in 2 years on saws which are hardly used.

Averaging 2 chains before they not longer cut straight. Kox, Stihl and Sugihara all consigned to a nail on the garage wall.

I use Aspen bio chain oil.

This is fine on the climbing saws and bars up to 45cm but it seems not to give enough lubrication on longer bars. My 500i oiler is on it's max, the saw is always clean and yet barely 2 chains in, the grooves are worn. Before that the 441 Kox then Sugihara met the same fate.

So I've a fresh Sugi bar, sprocket and new chains on the 500i. Tomorrow, before starting felling I'll empty the Aspen chain oil back into the combi can and trial mineral oil exclusively on this saw.

See how many chains I get through this time.

Stuart the aspen bio was the single worst bar oil I've used. Destroyed loads of bars. Make sure it's ok in the drums as it can go like jelly if not used up quickly. Tbh the stihl bio was the only one we ever got on with but at wear was always at least twice the rate of mineral oil. We had to switch back to mineral on bigger felling jobs especially saws like the 560s and 500i as the bio doesn't lubricate well enough on the faster saws. If your switching flush the oil tanks out on your saws with petrol as they don't mix well

Sounds like you're better off going back to bonfires and bowsaws mate

I mix proper chainsaw oil with new rapeseed oil 50/50. Works fine for me

First chippers now bars, your not having much luck mate.....ever thought of a new career ?

Poor man. Hate it when things stack up against you. I have use just veg oil in my saws, works well. Engineering cutting oil with water too. Dont have much faith in sticky oil. K

Do is a favour and post a photo of one of your chains freshly sharpened, from a couple of different angles, and preferably about 2/3rds worn

Years back, my local chap would routinely use a surface grinder to dress out a bar. He would also assess the gap and depth for us. Yes, we paid, but it was a good relationship and paid dividends in terms of freeing up people to do work and he was always there for us. Shame that his son didn't want to carry on the business. He couldn't then get a Stihl account then but we still brought stuff through him although it would have been cheaper to buy from a catalogue  (no internet in them days), as he always helped us at every turn. Top man!

Keep hearing this that if you mix veg and normal oil it turns solid maybe thats an old wifes tale then?

 

Who is right?! ?

 

I gummed up/knackered an oil pump when using veg oil but heard same happening with normal chain oil. Could be related to saw saw sitting awhile un-used in cold shed more than oil type?

Perhaps not so much with pure rapeseed oil; it's the last in the queue to congeal.  I use nothing else in my saws and have no problems but then I rarely use a big bar though I recently spent a day ringing up 24-36" with a 30" bar and don't seem to have suffered undue wear.

I never use any other veg oil; I think they do congeal.  Of course even rapeseed oil will over months.

Yeah might of being sunflower i used. 

 

You ever pull the clutches to clean out behind?

 

Thats where it all acumulated...
