removing paint from guide bar or tip

That was kinda funny

Science is not funny. It's fact.

...this is serious business.

Where does the heat go? If your theory is that the paint is keeping the heat in the bar because of its' insulation properties that insulation exists on the air side of the paint, too. You're claiming that the absence of paint is making the bar run cooler, if more heat was able to escape after the paint removal the bar surface should measure hotter, not colder.

The heat being produced by friction doesn't magically disappear because the paint got removed. The bar is never going to get hotter than amount of heat being generated by the friction of the chain moving along its' surface, unless you have a bearing failure or some other issue that increases the heat produced.

Please explain to me how the paint is keeping all the heat in the bar but still allowing your temp gun to read hotter on the outside surface. If the heat is being blocked from escaping by the paint how does it escape to your temp gun?

So how do you figure Redbull is getting consistently lower temp readings with his methods? He has already stated that he doesn't know how or why, or that he even cares. All he cares about is he is consistently getting lower bar and jug temps.

Diffision and radiation?

I wonder why they dont paint AC condensor and evaporator coils and why do they use cleaners on them? Wonder why they paint chainsaw bars and put grapics/names on them?

 

[Keith Gandy]

If we painted the radiator on our vehicle what would happen?

 

[KenJax Tree]

A radiator getting too hot is a problem, a bar is not.

Thats not the point

What about motor paint? Why doesn't it make motors too hot? Paint on mufflers? Or does hi temp paint release more heat?

 

[Keith Gandy]

Vehicle engines have internal fluid cooling systems that carry the heat to the radiator but paint the radiator and see what happens

A motor is powered by a divorced source. An engine uses fuel to make its own power. Hope this helps.

Does a motor depend on the block to dispate heat or the fluid called water traveling through the engine?

Is the bar (perhaps unintentionally) a heat sink of some manner for the cylinder?
Doesn't seem likely because I think the crankcase would be hotter than the bar.

IF On the other hand the running temp of the saw and heat generated at the bar are constants.
AND
the entire saw is a heat sink that has a constant additional temperature added by the engine running.....

crap I had a coherent thought but it escaped me as I tried to express it
carry on

Does everyone realize we r talking about powder coating and not paint on these bars? Do a goggle search on thermal conductivity of powder coating . Why do most highend automobile makers paint brake calipers instead of powder coating?

I think the unpowdercoated bar will dissipate heat to the lower surrounding ambient temperature instead of heat sinking to the cylinder. Sorta thinkin the path of least resistance

 

[KenJax Tree]

What im saying is does a painted motor run much hotter when it's painted or the same temp?
