That makes sense Pat with a long cut like that buried in a big sappy softwood I can see the binding problem. Bars and chains get over loaded with too much chip fiber jammed into the bar rails can loose alot of power then seize up .
I have a reconditioned 60" bar for my 090 that Sam Madsen gave...
Real nice, thicker bar rails with a .050 gauge too. The few loops I used up on my big work saws still have lots of meat in the cutters to go for another long time. I just switch to the round file when their about half used up.
I have no idea why Oregon made that chain in full comp sequence...
No wasn't planning on selling it, just gonna hang onto to it for any 30 years:lol:
I had plans to run it on my bikesaw but since Stihl introduced a timbersport .404 "high tooth" chisel bit chain it's no longer practical.
I've used up a bit of it on my 395 with the Alaskan mill and did a really...
Pat, I kinda figured that chain might have been old Oregon .404
With a 51 stamped on that chain's drive link that would make it a .058 DL gauge chain. If yours is .063 then it would be 52 chain.
Here's a half roll of very rare extinct .404 chain I own. Oregon 50AL which is full comp sequence...
From what I see in Reg's pic of his 3120..... sure looks like a full skip .404 to me. Wish I could zoom it in to see what brand that chain is , from the looks of the side links might be Stihl.
Actually those old medium contour sprocket tips were a better match for those long bars......a full size 2 7/8" radius with more bearings and larger sprocket for more strength and better cutting action with it's larger radius.
Yes very generous Pat . PNW loggers are a loyal bunch.
