Going to in red oak this weekend
I calculated it a 15,500+RPM if he's is truly pulling over 10600+ RPMThat's a lot lot lot of rpm for a 660 not sure if I would ever run one that high. I'm sure it would make a great cookie cutting saw.
Bad things can happen, but there are plenty of saws running over 14.5k.Only time I've seen a saw run past 14.500 was when I ported and decked my 044 and that was just to much lots of bad things can happen if you're not careful so I guess when he post the videos of him running it with the 11pin and the 8pin we should be able tell just by sound how hard he's running it at least I will anyways that's what happens when you are legally blind like me you hearing is more sesative to sound. Lol
Or making a living.Bad things can happen, but there are plenty of saws running over 14.5k.
Most aren't out cutting firewood though.
I'm not thinking rupdog is talking about a stock chain.Brand new RS chain .
Yea i had a ex logger bring me his fire wood saw ms390 and man I could count the little bits of the aluminum off the piston in the bottom of the crank cover ask him if he strait gased it and nope so I ask if he was messing with the carb yep and he said it was screaming like he likes. I said. Lol. Well go fin another saw this thing is all but junk now.I'm not thinking rupdog is talking about a stock chain.
RPMs along don't equate a fast saw, heard many saws screaming, screaming to their death because they were under no real load because of a dull chain, I actually just picked one up with a lightly scored piston, the chain was on backwards lol.
Can you post a picture of the tack that will shut me up I'm not trying to bad mouth you I just want to see what you saw is turning for rpm buy tack.Again purchase a $1399.99 fluke 820-2 stroboscope and you too will see the formula is wrong the saw runs at 13042 engine rpm on the tach not 15500 like the formula all of you are stuck on that is wrong . I have the instruments and I have proven it's wrong. That all but anything I do can be followed if someone is willing to spend the time and the dime for the test instruments.
Here's the red oak test log and the video with a 8 pin 25 inch bar or the 660. This will be the same log that test the 11 pin on also
What size and kind of wood?The 660 did run a faster cutting time with the 8 pin and slower times with a seven pin...
