Stihl Jet Saw

[Tree09]

That's pretty cool!

 

[BeerGeek]

I figure you'd need to wear welder/fireplace gloves to protect your forearm from the exhaust.

 

[Burnham]

Oh my...that is pretty scary .

People continue to be amazing in what they will come up with, eh?

 

[Mick!]

Doesn’t appear to be that quick through the wood though.

Combining the volume of a 2stroke, with the awful whine of an electric. The perfect saw!

Could cook your lunch at the same time.

 

[BlackSmith]

I wish the KMS4 would’ve worked out.

 

[Nutball]

I'm Stihl waiting for the ms900 turbo diesel.

 

[gf beranek]

Was that Jet Saw a factory build? Or a private build, proof of concept? Pretty interesting. Though hardly practical.

 

[Mellow]

I would have said Tim Taylor but there were no explosions and nothing burned...

 

[gf beranek]

El Cheapo Chinese 090. Has the look and the sound, and boy is it funky, terrible.

The guy in the vid is humble but doesn't know a lot about saws. But he will when he's done fixing all the bugs in this one.

 

[Bermy]

...I'm hooked, will that thing ever bed in and cut like it should?
The test cut was painful to watch. Sounds like he's planning to put it in a chainsaw mill to slab logs...good luck. His shoulders were slumped by the end but he's got hope.

 

[BlackSmith]

That WAS painful to watch. I would’ve sold him an empty cardboard box cheaper than $450.

 

[gf beranek]

I wonder that, myself. There's a follow up video. I'll see if I can find it.

Here it is.

Damn, it's actually cutting. But I'd pull that govenor out. Then it would really rip.

 

[lxskllr]

Does that seem about right for an 090? It doesn't look that torquey like I hear the old saws were. I want to say my 661 would blow that thing away. But hey, it's cutting wood, and no major component replacements. I'd call that a win for a Chinese saw.

edit:
I'm gonna have to fire up my 026 to refresh my memory on how it's behaving poorly. His slipping clutch in the first vid reminds me of the 026. I've been fixated on the motor, but it might not be a motor problem... If I remember right anyway. Something easy to check anyhow.

 

[gf beranek]

That thing is blubbering bad, smokey. It needs to be leaned out, and the govenor removed. Though that would void the Chinese warranty. Just kidding. With a little tuning that cheap 090 could run much better.

 

[BlackSmith]

I don’t think 105cc=090. Anyway, it’s Chinese, made out of chinesium, from China, home of the Red Plague. Dood should have his man card revoked.

 

[Nutball]

You can get a Chinese big bore cylinder to make it a 090, though I don't think China makes the big clutch which adds some torque.

 

[Burnham]

That's pretty sad, from first to last. Fellow needs some experienced tuning advice to call on, at the very least...first word might well have been, "wtf were you thinking?" .

 

[gf beranek]

I had (2) 090s, external clutch, rim drive. The centrifugal weights in the clutch had bonded brake linings. Easy to smoke the clutches if you were not careful.

 

[Burnham]

A whole lot of things it was easy to go wrong with when you put that much hp and torque in a small package. Add a bar longer than your truck bed to the mix...more than many could/can handle safely.

Reminds me of something Squerl once said when I was posting idle thoughts about upgrading from my 370 hp Jaguar to a 520 hp version...something like "once you get past 500 hp, it's mighty easy to run out of talent".

Running an 088 or 090 is rather like that.

 

[pantheraba]

That's a great saying!!

 

[gf beranek]

Brian has a keen knack for hitting the nail on the head.

Combining the volume of a 2stroke, with the awful whine of an electric. The perfect saw!

I'd say that's way over the awful electric whine. I saw a demo of such a small jet in a big RC show. That move the ears qute a bit! Less than the heavily moded saws, it isn't the same scale, but the electric saws would still look more like a whisper beside the micro-jet.
