Ported 088 and 3/8" chain

[samdweezel05]

Should I worry about tearing chains apart with a ported 088 wile milling in bigger 32"+ wood? I broke a 3/8 chain with a ported 660 on the mill this summer. I have milled with big saws and .404" but I want to try 3/8 but I will need to buy a bar just for 3/8 chain.

I wouldn't know till I tried it. I would guess it has some to do with how hard you run and how aggressive you are on the chain setup. Just thinking out loud. Good quality chain should hold up I would think.

I think your gonna snap chains if you really get on it.

send me the 088 and you wont have to worry about this anymore


.404 on that saw

hey phil,
did you get those pictures i sent ya ??

If you g

. . . but I will need to buy a bar just for 3/8 chain.

Roller instead of sprocket nose bars solve this problem.
If your chain is setup setup right you should not be breaking 3/8 chains.
I would be interested to see a photo of the broken 3/8 chain from the 660? Take the pick fully side on as large as you can so that it will still be in focus.

It was a brand new Windsor 36" full skip fresh off the roll. I had never taken a file to it. I usually run new chains as is until they need to be sharpened. Then I go down to 10 degrees and set my rakers accordingly. I only ue stihl chain but I had this Windsor given to me.

And now that I think of it, it broke the connector link.

I'm glad I saw this Phil. So milling will be your 088s main job? I port saws differently depending on use.....

 

[mad murdock]

Windsor chain is softer than stihl chain, don't know by what value. Stihl chain is also pre stretched making it a bit tougher. I would surmise a good ripping chain in 3/8" should perform satisfactorily.

Milling is its main job but it will fell the ocasional tree, buck the occasional larg log and have a 9 pin rim with a 25" bar and 3/8 chain for fun stuff at get togethers. Sounds simple enough, right?

You'll need to be able to start it in the mill, and it will be making really long cuts. That means no timing advance and less compression than my "normal" builds.

I wouldn't worry too much about that. I don't mill stuff big enough to need refueling in the cut. I am also not a little guy. The old 075 wasn't an issue to start with out useing the decomp when laying on its side. If the long cut times are the issue, then by all means, build it how it needs to be built but don't worry about too much compression for starting in the mill. I will probably put 3 gallons a year though it on the mill. I am not a production miller nor do I mill a lot of stuff that wouldn't be faster with the 660 anyway.

The starting in the mill issue was directed more to timing advance......that can make an 088 hurt you.

So the compression issue is more about heat I would assume? I just want a srong saw, that's why you have it now. We will call it a milling, bucking, felling race saw

Listen to the man Phil ,when i have to restart the 660 on the mill after been running it ,the too much compression makes a difference,I am glad there is a little button on top of the 660 now ,quiet after running for 6-10 hours is a plus too ,i have 2 mufflers ,a stock one with the tiny hole and baffle ,and the Mastermind dual port,i recomend the narrow kerf ripping chain too ,stuff gives the boards a real nice finish,am glad have the 2 066's now ,one for strictly milling ,one for play

 

[samdweezel05]

You won't catch me running a saw 6-10 hours a day. I'm not telling him how to do anything just trying to be accurate with how it will be used. Anything will be an improvement over what it is now. I am curious what he finds when he opens it up. I am having him do crank bearings and seals too.

How many tanks of gas before you resharpen?

Depends on the type of wood or how clean I make it before I mill. I milled all of this and never sharpened the chain. In fact, this is the log I broke the chain on. The last cut was just as fast as the first. I sharpen when speed is down.

 

[BobL]

I touch up every tank of fuel whether it needs it or not. When using a powerful saw it can brute force it's way through smaller softer woods and not seem like it is even slowing down. Even though a powerful saw can do this it still pays to ease the load on the saw by regular touching up.

OTOH it sounds like you just came across a weak link.
I have milled more than 100 hardwood logs (some of them much harder than dry hickory) with 3/8 chain using an 076 and an 880, I have hit rocks, glass, steel and concrete, but have never broken a 3/8 chain.
