12 volt wood saw ideas ?

[todd]

Please post the efficiencies of a dedicated generator and a car/alternator setup.

Circular or sawzall? There are battery versions for both.

I'd like to find a 'plug' that I could wire myself to do exactly that. Otherwise, I suppose could make one from wood. A twelve-volt car battery is used to putting out more amps than a saw draws.

Would it not be difficult to use a bandsaw for cutting up pallets?

I'm curious, why isn't an electric chainsaw an option? IMHO, it is the ideal tool for hacking up pallets.

First you would have to compare apples to apples. Most any automobile engine runs more efficiently than your typical portable dedicated generator engine. Any you could probably run 15 alternators on an automobile engine if that was all that was expected out of the engine.

Ironically the Green energy hybrid automobiles with the huge battery arrays that are suppose to pollute less really don't. They pollute worse in a different way. Those toxic batteries have to be disposed of every 60-75 thousand miles and that is a nasty problem. I am shocked that California allows these cars to be sold there.

[Leon]

True, however only for "very" short bursts at a time.

Or get an after market alternator for your car that puts out 120 volts. Actually automobile alternators produce A/C current and the internal rectifier bridge converts the current to D/C. IIRC one of the Pontiac SUV's has 120 outlets.

Hello Fred

Just the oil, want to sell the wood so trying to keep it clean for the customers. Plus as a woodworker i have a 'thing' about oil, not allowed in the workshop, messes up everything.

[todd]

Fine. I'm just asking for the numbers. You seem to know it's the case, so pulling some numbers with a source should be no problem.

Common sense will never get in the way of a good Californian.

[Leon]

I agree that pulling the numbers should be no problem, I suggest that if the numbers are that important to you, do a Google search and or request this information from the manufacturers.

Hello Fred I like that idea, with an electric chainsaw you only need to lubricate. Anyone used the 'ex deep fry oil' for this ?

However if you are going to make an assertion that on the face of it seems unlikely (a 200 horsepower engine running at near idle to provide the couple of horsepower necessary to run a bandsaw is _not_ going to be more efficient than 2 horsepower engine running full throttle unless that 2 horse has something badly wrong with it) and then not support it then the rest of us will decide that you are a loon.

Why not just use a cordless saw? There are vehicle chargers available for most systems.
