V8 Chainsaw (Predator) by Rotax Robert

Ekka · 2nd March 2007, 08:12 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.

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.

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

TREE-SURFER · 3rd March 2007, 11:25 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 · 5th March 2007, 09:26 PM

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

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 · 17th March 2007, 07:06 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!.
