Electric Saw 24 Volts

[Kenskip1]

Ok here we go. I have been viewing the picture of the Predator. It apears to have been on steroids for some time. The weight of this beast is in a class of it's own. The noise could possibly be heard for miles. The fuel consumption is way out of this world. The safety precautions may have to be added. Spark arrestors?
Now my challange is simple. Come up with the worlds first high speed Electric chainsaw. The simplest way would be to start of with a portable Electric motor. A V-16 Caterpillar starter would be a grand opening! The Electrical supply would be two 12 volt batteries wired in series. A foot operated switch will be used to start this thing. Not only would the EPA be happy, so would the operator. Any other suggestions? Ken

First thing would be to gear up the motor. The torque from the starter motor is huge, but the rpms are too low for a direct drive.

Good idea but it has already been done, and yes, it will give the Preditor a run for it's money.

I think a starter motor would require some changes, like addition of a cooling fan and vents. They're really only designed for a few seconds of opertation at a time and would overheat without being altered in a saw application.

I'd think for a RACING saw, electric might be pretty competitive. Since there only cutting for a few seconds at a time the battery or even just a capacitor wouldn't have to be that big... There are electric cars right now that will beat a Viper in the 1/4 mile.

Although I can't see Rotax Robert converting the predator to electricity anytime soon, not enough noise and mayhem to put on a good show!

The Predator is cool, but this bad boy would turn it into tiny pieces real quick!

We built these where I work. We bought the cutter drums and built a combination steel and aluminum housing/frame to lighten up the heads. The aluminum shield around the drum is lined with UHMW plastic for wear resistance. I've seen it in action it's pretty awesome. The cutter on this machine is flail type. It can start about 30 ft up cut the tree into and just keep lowering it down to the stump nothing left but mulch. The old brush cutters used bush-hog type blade and occasionally it would throw one through buildings, cars and even a mobile home once along the side of the track. We don't have that problem with this design. It has a 675hp Cat engine supplying the electricity to the traction motors and the pumps for the hydraulics.
