Chainsaw Repair

Found a post from 2010 I made.

For you guys talking about stihl and oregon chain cutting speeds. I tested cut speeds of stock chains and machine grinded and atop square guide filed chain. I dont think I had a fresh loop of LG to try. The atop chain was oregon LP 058 goofy and square filed and then my 30 min square atop filed.

I was a little disappointed in my round grinder results I tested for fun too.

I found a nice clean 10"x10" very dry poplar cant in the barn that has been there for well over a year now.

Saw was a 357xp 7T running 93 octane 32:1 and a rich 13.8k. 3 cuts per chain, which allowed for the unseen knot hit and operator error in some of the times.

Chains were work chains tested.

I know factory sharp chains are not the sharpest out of the box, but I wanted to have a base to go off of. So RSLK, RSLHK, CL, RS, factory sharp were tested.

Kevin, what angles and what kind of wheel was used on the RS?

Old chain test 2010. Bump for member looking for info.

CL is the square version of the LG round. LGX replaced LG.

Mike didnt you do cuts comparing LGX and RS.   I compare LGX right with RS in the cuts but never timed them.
