wood dust in the carb hard on the saw?

[Hermio]

I don't recall, honestly. Must not have been very impressive.
For posterity how about you re post it?

Go back to the oil thread and re-read it.

 

[Hermio]

Thank for proving my point!

Are you really suggesting thet thermodynamics has something to do with rheology? Pathetic!

 

[MacAttack]

Is this thread still about sawdust?

i have a Mini Mac that I ran for about 25 years before I realized it was missing a rubber washer that kept sawdust out of the intake so it was probably eating sawdust the entire time. It never lost power or compression the whole time, but I haven't taken it apart to inspect the piston skirt.
I also have an old 10-10 that was ingesting sawdust before I got it that has some scuffing on the intake side of the piston but has great compression and runs perfect.

What's really pathetic is your autistic, old azz.

I did. Not impressed in the least. A CE that specialty is simple mixers. If you were good at what you do you by your advanced age you would have been a senior VP or some such for years by now. Instead your a sporadically employed mixer donkey. The other thing is any CE worth a damn is working on large view process related items, not essentially doing the job of a ME.

Walker. I like you really. But, take a pill. Jesus.

This could be the first thread about sawdust that gets closed by the admins...

Just diverting the attention from your ignorance rather than addressing the issue, I see.

Fluid agitation is not at all simple. What I do involves mass transfer, heat transfer, fluid dynamics, rheology, shear, etc. My clients include large engineering firms, who do not have staff that are sufficiently knowledgeable to do the job internally, as well as many end users. As for being a VP, technical talent does not necessarily translate into managerial talent. I know myself well enough to know I would not perform well in a managerial position. If I had somehow been promoted to a VP, I would not have been happy in the job and would have likely failed at it. I have been content to excel at the technical and communication aspects of my career, and leave the managerial stuff to others.

I bet you co workers through out your career saw you for the autistic weirdo you are.
At least you recognize this..

No. Just stating the obvious, Greg.

Do you think I provided that list to impress you? I bet you would not be impressed if I walked on water. No, it was not to impress you. It was to demonstrate my qualifications and to challenge you to try to match it. How many things have you gotten published?

I was never diagnosed with autism, but I think many engineers and scientists have it to some degree. Since my colleagues were also engineers, whatever tendency I may have in that direction would be viewed as pretty normal. But I am sure your colleagues really love your anti-social personality.

Don't kid yourself, you were never viewed as normal.
I have worked with alotnof engineers. The good ones are not autistic weirdos like you. And that's why the are running company's and not designing poop agitators.

None of what you posted makes you qualified more than anyone else here to comment. In fact your demonstrably less qualified in practical matters of chainsaw operation and design.

Once again, you demonstrate your lack of reading comprehension.

Amazing what a bit of fines can do to ones brain, let alone a saw.............

Actually, I conceded long ago that you have more knowledge of small engines than I do. But your knowledge of fluid dynamics is basically non-existent. No one with any knowledge of the subject would conflate viscosity with film strength, much less thermodynamics with fluid dynamics. I have shown that viscosity and film strength have different units and different dimensions, and that higher viscosity does not necessarily guarantee higher film strength. A practical example of that is gear oil. At my old employer, large gear drives were part of the product. Field experience has shown that oils of the same SAE viscosity index produced different results. Specifically, the gears lasted longer with oils that had an EP additive package, which gave them higher film strength.

Except that statement i made in regards to viscosity and film strength was made with caveats and under certain conditions. You conveniently gloss over that because you're an autistic weirdo and it doesn't match with what the college course you took 40 some years ago said. In short you lack any sort of critical thinking skills beyond what a book tells you. And that's why your an old fart that's still designing poop stirring devices.
And no chit an EP oil works best in a EP application.

You claim I am autistic. I did not say that, and no doctor has ever said that. I guess you claim to be a doctor, too! My knowledge of fluid dynamics is not based only on what I learned many years ago in books. It is based on over 40 years of practical experience working with fluids every day, and I publish technical articles on the subject. Your "caveats" do not remove the fact that you said viscosity is essentially film strength, and you are also confusing film strength with film thickness, which is in fact dependent on hydrodynamics, even to the point that air, which has an extremely low viscosity, can produce a film thickness sufficient to prevent metal to metal contact under certain conditions. BTW, I am not working on agitating poop. Today I am working on a project for Shell Oil to design a continuous flow multistage reactor with non-Newtonian viscosity characteristics that change as a function of degree of reaction conversion. I calculate residence time distribution and stage efficiency, accounting for backmixing between stages.
