This is why long bars cut faster than short bars.......

They give the impression of cutting faster mostly because of more teeth and they stay sharp longer. Letting you cut more wood per sharpening.
 
I will say this, long bars are harder to match cuts for me than short bars.

Everything has its place.

For me the weight factor does not increase speed because I usually cut sideways or up at a angle;)
 
In that second video, you can't use that FLIR gun to measure temperature unless you calibrate it, and you can't use it again bare metal like he's doing. You will get false readings. I use one at work and that's a common mistake that people do with them.
I have noticed that as well.. Where I used to work we used them to measure gearbox temperatures, and it was a polished aluminum case. It would burn you when you touched your hand to it, but when you pointed the gun to it it said it was about 120F or 50C... Put a piece of electrical tape on the gearbox and it would jump to 160 or more. They have their applications, but they need to be used with caution indeed

Yup, I've seen that a lot. It has to do with the emissivity of materials. Using black electrical tape is a great way to get an actual reading. There are several time in an electrical panel I'll see pretty much a reflection looking right back at me when scanning the panel. The same is with those laser temperature guns. The further away you are, the more area you are taking an average of and if you try shiny metal, it can give a false reading.

My experience is just with the laser guns.. though the laser is nothing more than a pointer for cats to chase
 
Long bars cut faster because they are attached to a bigger power head!!!!

Phew.....that's good to hear! Thanks redoakneck!!! I just bought an 066 with a 28" bar because my MS260 with an 18" bar was too slow in big wood. This thread just about had me convinced to return my 066 and get my $50.00 back!!!!!
 
A longer rifle barrel is exactly like a low exhaust, the farther the charge can drive the projectile the faster it will travel.

Why that's not true at all. Up to a certain barrel length yeah, but assuming two identical rifles with the same charge/projectile, beyond a certain length the remainder of the barrel just creates drag and slows the projectile. Modern powders burn fast and get done early. Plenty of short barrel versions of the same rifle produce higher velocities than their longer brothers. Plenty of evidence for this all over youtube with people who are setup to do this type of testing recording the data.
 
Jesus man u read a lot into that don't u? I didn't say a barrel 10 foot long is better nor a exhaust at 110, there's a point with anything that u start going the other way.
 
I am in my prime but there's lots of manopause on this thread. Glad me and my Stihls were made to endure an elongated peak in our respective power curves.
