Speed Test
« on: January 16, 2018, 07:10:25 pm »
Not to sound like a jerk but I see plenty of cookey cutting to test saw speed on a log, But what about cutting a 16" Oak log for 12ft, milling I guess you'd say. What kinda performance would be needed for a sustained cut? WOT for 10 minutes, that's about  what it takes me in Red Oak of that size.
 Just a thought cause I been milling some 18" and less stuff and wondering how the ported, high compression saws would hold up or do better?

I did a lot of milling with ported saws. Some 26" wide cherry 6' long was 6-8 minutes. I was testing fuels and oils that way. I made an oak cant 12x12 4' long to test fuels. 3/4" thick is about as thin as my mill will cut

I never milled with a ported or compression modified powersaw. A stock Stihl 090AV or a stock Husky 395XP is all I use on a 36" Alaskan running square ground chisel bit .404
I milled alot of 16ft 2"x12" DED killed American elm. You won't find much hardwood tougher then thst dead elm.
Good edge on the chain takes me 5 minutes for a 16ft cut making 12" cants.
Another thing I do is mill in winter time when it's -30 below. Carb is set richer for that cold, saw has no chance of overheating, chain runs cooler and boy that extra cold oxygen sure make those saws run nice.

That temperature would kill me,

 but the 660 pop up piston got me thinking, high compression and high rpm's or lower compression and rpm's for the milling or long cuts

You quickly learn how to dress for it and you don't want to be restricted in movement by wearing senseless bulky clothing.

Far better working conditions working in 30 below then trying to stay cool while working  on a hot day.

You don't want crazy compression starting it on its side with a mill. 185-195 is fine. I've run all kinds of ported ones on the mill. I've milled at 10-100 degrees.

Big concern for me is the extra heat generated with a too high of a compression ratio on those long cuts at WOT.

Once you try milling with a square ground or filed chisel bit chain,  you will never want to go back to round sharpening.
