Spuds Porting and Tuning Thread

You remove the corner of the tail. It helps make the chain smoother as well.

You would buy it because it was one of the more affordable 3/8 chain available at the time. Since you would be grinding on it, you wouldn't bother starting with square chisel. RS is out, the teeth stand shorter than it does on Oregon chain. Oregon chain, with the taller teeth, have more chip clearance.

 

In any case, that was to show you the basics of how to make a chain faster. I would assume most would get the idea.

 

I accept your point about LP being taller than RS - its very noticeable if you put them side by side and explains why Stihl recommend a smaller (5.2mm) file for 3/8 chain.

 

However LP and LG are both round ground chisel and it must be difficult to grind the LP's drivelink down with the raker in the way.

They likely wouldn't be doing the bumper link by hand. In any case, if it is bothersome, use a non bumper chain...

Just clipped the heels on my 357 chain, not gonna do it on the 560! 357 is on 15" and took forever! Don't fancy doing an extra 3" of chain!

I forgot to lift a saw out the shed this morning, will do it tomorrow and get into my work and get the finger file in about it:biggrin:

How did it cut after?

I finished it an hour ago! The saw itself cuts like it's on speed, but it's ported and has a muffler like a colander to stop it burning pistons.

My boss, who traditionally is against porting, wouldn't put the saw down!
