Chain tension

Those solid nose bars do behave strangely - I think they were good back in the day when saws did not rev so high and sprocket noses on bars failed more easily....

 

These days they are a pain - the chain goes tight - you slacken it - the chain runs then starts hanging off the bar - you tighten a little - suddenly it goes really tight!

 

You just can't win! You can only look to manage the bar as best you can - ie keep altering chain tensioner to suit.

 

Stihl are behind the times here not producing a 4ft sprocket nose bar - they have the 36" and 59" so why not a 48"? It's odd....

I've been looking at getting a 3120 but it seems husqvarna only do solid nosed bars as standard. Not just still who are behind the times.

When milling you're asking the saw to work much harder and keeping the chain in contact with full width timber for a lot longer than when using a saw to crosscut.

 

From a mechanical point of view, it's a lack of lubrication due to this extra work causing the heat and associated stretch. Therefore surely a cheap additional oiler should be the first point of call?

It could seem that way - but when using a sprocket nose bar these issues don't happen - same length bar, same wood, same lubrication yet it just doesn't happen to anywhere near the same degree with a sprocket nose bar....

 

 

 

That said an additional oiler would certainly help - but really why not just put that cash towards a new bar?
