V8 Chainsaw (Predator) by Rotax Robert

Eric Frei · 3rd March 2007, 02:12 PM

For those of you who dont know Rotax is the brains behind the worlds fastest chainsaw.

I'm in the process of putting a vid together, but here's a classic off the net to let those of you who don't know of him and his saw what it's all about.

You Tube

I believe he's a machinist/engineer bloke for Boeing, so has the techno skills for building a monster like this with accuracy and fine tolerances. I believe he had to build many components including the bar etc ... aint no saw shop helping you out here.

Enjoy, and Rotax, keep winning.

Oh, and here's his most serious competitor, the Binford saw.

A legend!

Drouin Tree Service · 3rd March 2007, 11:16 PM

Really well put together Ekka,how is the throtle used on that saw Robert?certainly alot of time and preperation building it.

TREE-SURFER · 4th March 2007, 05:25 AM

That Binford Ekka, you can actually see the chain lifting off the bar. Some piece of kit.
Wonder what horse power it runs at. 0-60

Rotax Robert · 6th March 2007, 03:26 PM

Throttle is a thumb lever like they have on ATV. Nice work EKKA I'll get you some video this comming season.

Rotax Robert · 15th March 2007, 03:49 PM

This is my Double Ender Racing Chainsaw cutting a 34" dia log. This setup has never been defeated.

That doubled ended job, an engine each end.

Sorry, I just thought if that chain busted some-one is gonna wear it, there's no safer end?

There's no doubt about you guys with ya saws, ya'll friggin mad!

I really enjoy the entertainment, it's surreal.

TREE-SURFER · 18th March 2007, 01:06 AM

Rotax - Revving those beasts up for the first time with a chain on, does it not make you a little bit nervous. They look awesome. But like Ekka said, ya mental...I'd poop maself using 1 of them..

Found these pix of old saws at Myerscough College taken when I was there training. (The Pictures - not the saws..

) Savage beasts...

Hi Rotax Robert,
The heat from the harley engine must have been bloody hot wright beside your arm,did you get burnt or at least singe you arm hair??did the Vtwin feel like a small version of a 8 ??and was it a shovel or a evo??.It sounded good!.

it would have to be a Evo,

Evo, and yup on the double ender you will notice that I am not on the dummy end.

Rotax Robert · 22nd May 2007, 05:18 PM

Had the 1st show of the season and the mighty Predator came out on top with a 1.04 second cut. Here is a pic and I will get some Video off to Ekka to put here when I get it down loaded.

Eric Frei · 22nd May 2007, 06:11 PM

Hey, that looked like a HD Camcorder on that tripod, I can process wide screen HD no worries and even format in HD WMV WIDE SCREEN.

Haven't had a camera capable yet though so that one on the tripod looked like the candidate.

JohN Dee · 22nd May 2007, 07:14 PM

Great Saw Rotax!

So many times when we are bucking up HUGE logs I think in my head: If we had that predator saw here, we'd be done now

Rotax Robert · 23rd May 2007, 09:11 AM

The camera belongs to CMT "country music television" we were doing a tapeing for an upcomming special on TV so I wont get the unedited version I am sure. It is supposed to air on August 3rd.

Rotax

Rotax Robert · 23rd May 2007, 09:13 AM

I had these guys in my boots with me all day. It was fun though.

Rotax Robert · 15th June 2007, 01:17 PM

here is a vid of the Predator last weekend.

Eric Frei · 15th June 2007, 04:54 PM

What was the official time on that winning cut?

Rotax Robert · 15th June 2007, 05:11 PM

I think it was 1.5 or 1.6 thru a 32"+ log

Eric Frei · 15th June 2007, 05:14 PM

That's larger than normal log right?

When you win what do you get, like prize money, maybe $1K or more or less?

Or maybe bugger all but a shiny trophy.

Have you pulled down the engine since you built it?

Rotax Robert · 16th June 2007, 09:16 AM

Normaly we shoot for 30" diameter, this one was 32+ but I did not get a chance to measure circumference as I usualy do to get a true volume of wood. This show you just get a trophy as all the $ goes to Busted up Loggers.

Rotax

Eric Frei · 16th June 2007, 09:35 AM

I bet you have a shelf full of trophies then.

What about Guiness Book of Records, you in there yet?

Rotax Robert · 16th June 2007, 02:58 PM

Heck, they don't have a class for saws as I could see.
