Chainsaw Repair

Your welcome W262.
I milled with almost every brand of LoPro 3/8 chain since the early 1990's. Oregon 91 is just as strong as Stihl Picco.
I just started a few years ago milling with the 63PS chisel on my 066. Cuts even better then the PM. I just sold my 066 but have another 066 (bit newer) which I'm setting up with the Picco spur sprocket drum.

Stihl has sold the 066/660 7T Picco spur sprocket drum for years (longer then I remember) under the Logosol brand name . I also got the Logosol Stihl bar.

Now to explain better. I mill the slabs off the big logs 20" diameter and over with my 090AV or 395XP with 36" skip tooth .404 square filed chisel chain.
After I get the squared cants made I mill the lumber or beams off with the 066 with 16" Picco b/c.
The reason for the narrow kerf Picco is I can get an extra piece or 2 off a cant.
Think of an extra couple of 2"×12"×16ft pieces of lumber.
