Stilh 066 7 or 8 rim sprocket?

[Trigger-Time]

For milling Red & White Oak, 16" wide or less cant's is 7 or 8 tooth better?
Would like to here from some that has tired both sprockets
It would save me from trying to find out for myself.

I used 7 and 8 tooth today, but when I put the 7 on, I also put a
new chain on and it cut allot faster, I know a new chain makes a
very big difference so, it was'nt a fair comparison of the 7 verses 8.

Also some pics of White Oak milled today.

Nice pics. Trigger. I dont believe I saw the new toy in any of those pics. I think Ive heard some of the other guys in here say that you will get faster chain speeds with the 8 tooth sprocket.

Faster chain speed, yes. But not really what you want when milling...You need the grunt of the saw. Not to mention the faster the chain spins, the less oil you are getting on the chain.

More speed equals more friction too, which equates to more heat in the chain and bar, also things we dont need to add to a milling situation.

Thanks for the milling pics trigger... nice looking clear white oak slabs. Don't let them dry too fast right away. I have never used anything but 7 sprocket, so don't know what the 8 sprocket would do for ya.

Nice pics TT. What were you getting time wise per cut?

I'm going to use the new toy on the mill after the 90 day warranty is up.
So if some dose happen to it, I will be-able to honestly say no it has not
been on a mill.

About the 7 or 8, I know the 8 will have a faster chain speed, but at
some point it would be like going up hill in your truck with a load on
and needing to down shift. I was hoping that some could tell me when
to down shift so to speak. I would think after a cant is so wide that
a slower chain speed, but more power would be better.

A few more pics, And dusty for you one with the new toy.

Thanks, Gary

TT, Ive had a 20" bar on my 660 in the mill cutting 13" Ash, and I still wouldnt have wanted the 8 tooth rim on there.

Casey Thanks, That makes sense to me.

For the 15"X6' = 3 1/4 min. with chain that I had used a file on, then cut
the cant,and had the 8 tooth on. Put the new chain and 7 tooth on
turned the cant, it tapered 11.5" to 9.25"X6'= 2 min

Woodshop, I'm going to put the lumber in the barn, it has a old corn
bin in it for ear corn. the bin has a concrete floor. The bin was made
to store corn and also let it dry, I was thinking it would be a good
place to dry wood.

I ordered the book (Understanding Wood ) by R. Bruce Hoadley (Hardcover, 2000) that you have talked about. I need all the help I can get!

Thanks, Gary

That White Oak is a B**ch isnt it?!

Yes, But I really have not done a enough milling to know.
Lighting got this old tree 2 or 3 years ago. I have only milled
a few slabs of dead red oak and eastern red ceder. Man that
ceder is fast milling wood 10"X8'= 1.5 min and the chain stays
sharp lot longer.
