here is some second growth cedar out behind my house ,old growth around here is 6-8 feet across ,that is a 32 inch bar for reference .,seems like the 4-5 footers always have rot in them when fall them ,so lose 8 feet or so of first log
Had to rip the bottom one down the middle to move it with the skid loader ,got a lot of nice trim boards out of the rotten log still ,was all clear tight grain no knots View attachment 447402 View attachment 447403
The old growth here is almost always unsound for the first 6 feet, especially hemlock. Our trees are also much shorter than yours.
Our growing season is so short you rarely ever find old growth over 4'. The old growth I have seen is mostly all in a private old money club up here, called the Huron Mountain Club.
 
Not the results I read. Best I remember H1R burned the cleanest compared to the others.
I've never used H1R. I've used Belray mc1+ many years ago in my CR dirt bike.
I've used mostly 800 off-road in my saws and willing to try something else.
Was the test you are referring to the one that also noted that H1R required a large tuning change?
 
here are my 3/8 vs 404 tests

I think 404 RS is a little much for a stock 661. It's rough in the cut..BUT it depends on the wood type. Ported saw I'm sure would be way better. Time wise it's right there with 3/8ths most of the time...depends on the wood....sometimes it's faster even.

I think 404 RSLF is freakin awesome at any length on a stock 661. It's smooth and it's right there.

These are all new chains in the tests...the thing these tests don't show is what happens after you've been cutting for a tank or two? I would bet money the .404 stuff is doing better on speed because it's stays sharp longer.

vids if you wanna watch -







gotta figure out the 36 v 41". That's still in pieces...need to edit together.

36" tsumura 3/8ths RS 45.0 1:01.9


36"tsumura 404 RS first time using at this length ...stuck, then in 2nd cut I let it self feed 1:01.7 so .2 sec faster than 3/8ths lol

Lol!! I may have a MM390 that will probably make you drain the gas out of that 660 and put it on the tradin post!! Lol!!
LOL...I wouldn't argue with that. That's why I'm getting a 390xp if I can ever get if off lay-a-way. Too many family expenses (two girls in college and one in Jr. high). I wish my Grandpaw, deceased now, could have tried my ported 660. I think he used a Homelite during his Logging days....cross-cut saw originally.

I bet they would too. They were workhorses in their time though.

It could have been....not sure. I went from using Stihl 2-cycle oil to Redmax and a few other "chainsaw" oils. I've only been using 800 off-road lately but I might try the other oils AS members have recommended like Mobil and K2. I doubt my limited amount of saw-time will ever make a difference though. I don't use a saw professionally like you and other AS members. I do appreciate the knowledge and input though.
 
I run 16" and 24" 3/8 .050
Its up to you, but I am willing to square file a new chain for you.
If you dont want a new one, I have about a dozen used 84DL chains hanging on a nail ........ all square filed, cleaned gullets, and rakers set.
Run it and let me know how you like it, then its yours to keep.
You can send it back for the first re-filing free of charge (except shipping of course) ................

Just PM me any address that you want it sent to
 
I get longer life out of square than round. We milled with a 37" skip square yesterday on a 394. Jason had bought some R50 and it was smelling good around that wood pile with that and the VP fuel Rodney had.


So I should try the 36" 3/8 RSLF on the green wood next time I get some(was saving it for cookie cutting wile still square),
And I'll do a video rslh in hard wood just cause :) or keep it for some pine I have lined up down here
Been using A3EP gradually taking it to 10 deg, now it there finally got some good results,

Also I'm using 32:1 @98ron turned down a bit for the mill
