Diesel Chainsaw on its way

Simple question can we run it on red:001_smile:

If you think 2 stroke fumes are bad, try diesel fumes:thumbdown:

 

Ok, I know some of you love 2t fumes.

I believe that neither diesel, nor battery powered chainsaws will ever become mainstream for professional users.

 

The reasons:

 

Diesel: Weight. Diesel engines have to be heavier given the power requirements.

 

Battery: Bulk, weight, power, price and recharge time. Bulk is getting better and may be fixed with new battery technologies (lithium-ion or newer technologies). Weight is getting better. Power can be achieved (look at the Tesla car), but at the cost of bulk and extremely high costs. But recharge time is going to be a problem. A pro saw have to be powered by a 3.5 HP = 2900 watt engine. You'll get about 5 minutes running time (at best) on a battery pack, and recharge time will be 30 minutes minimum. This means you can work 10 minutes every hour, or you'll have to have 6 battery packs for your saw AND have access to a recharger on the work-site.

 

Don't believe it until I see it.

 

For home owner saws with low power requirements and low duty cycle, sure. But never for pro users operating far from electrical sockets.

 

Wouldn't say never mate. Not in our lifetime, maybe. But necessity is the mother of invention and all that. When we need it, someone will figure out a way. Would love a quiet saw, no more ear defenders. Make the job a lot safer.

Battery / electric saws could easily become reality

They've gotten around this.

WRONG, WRONG AND WRONG! I spent 13 years in diesel exhaust emission research (uni of plym, uni of leeds, uni of glos'shire) so don't get me started!

The last thing I want to do is get you started TCD, as I know you know your stuff.

After a long earlier life of working on Ag diesels, and now have been away from them for 10 yrs, I now feel physicaly sick when exposed to fumes from the odd diesel I service.

 

I expect its in the mind.

 

Oh, and I re-read your thread, the bit about veg oil in the saw, so I probably should not have posted the bit about diesel anyway:blushing:

[blazer]

Maybe 'landrover' are making one - will leak oil, weight a ton:sneaky2:

 

Hang on a few yrs and we could have a reliable Jap one:thumbup1:

[fergusonforestry]

it wont last long and cost a fortune for parts then!

Is there any were to put a nuclear reactor ? you could put were the air filter was then you could cut for the next 300 years stopping ! Sorted .

You would need to fit a urine catheter to the operator then, or an 8-generation relay team, that would glow in the dark.

 

Don't even think about putting one in a submarine:001_tt2:
