Chain for Aluminum?

[trimmmed]

Carbide cuts best, in particular a carbide blade designed for cutting aluminum. On a circular blade it would have a triple chip grind on it. The triple chip tooth looks like a reg tooth with the sharp point chamfered off.

But with a chain............ the heck with that, no recommendation here, aluminum is very "grabby"

I have heard of chainsaws being used to cut up airplanes! A friend went to salvage the engines off of a crashed twin. Out came the chain saw and the engines were laying on the ground in about 5 minues.

get one with many teeth as possible for best performance...

This needs to be posted in the "women with chainsaws" thread...

Try this if you want fast. Lots of PPE, a 12" 40 tooth carbide blade on a Stihl cutoff saw. Fast but dangerous. Tried it to take a stump out. cuts fast and doesn't get dull the first time it touches dirt like a chain. Just remember the stihl has a 20mm arbour and the blade will be one inch, you need a 25 cent bushing/spacer to mount it. (redneck stumper)


BE CAREFUL!

I wouldn't.. Kickback is severe.. and the carbide tips come off like bullets. Stihl has a nice video of a guy that lost his head when the circular saw blade came off... a big no no...and in the operator manuals of cutoff saws.

On Stihl cut-off saws: The 25c bushing or those supplied with 1 inch blades DOES NOT WORK, and even if it appears too, is a disaster waiting to happen. The supplied bushings are only the wide of the blade. The construction of the holding washers on either side of a stihl cut-off saw leaves a wide gap. The bushing will slip to the side and the blade go eccentric. I see this all the time on abrasives when someone buys a 1 inch set with adapters. Stihl has the correct bushing (it's 1/2 inch or so wide) - it's only a few $ and is available in plastic or brass.

Make sure you use a homeowner saw. Would hate to you get shocked when you cut through the 110v power feed with a mag case saw.

No Fred, It was a Felony for me too.......




What kind of notch do you prefer?



.

I think he uses the gap w/snipe notch.LOLOL :rockn: :biggrinbounce2:

Uh, 110v would be like getting tickled. I would figure more like 277v or even 440v. opcorn:

Hahah...

Just remember that current is what kills, not voltage. It only takes a fraction of an amp to do the job.

Yep! Just a few milli-amps through your heart may cause it to go into fibrillation. Cut a 110v hot wire and you will burn a small hole in the jaws. Cut a couple of legs of a 277v line and you will have a proportionally larger blow-out hole. 277v hurts. One tool buddy of mine wasted his Kleins when someone turned on a breaker on a lighting circuit he was terminating. (Needless to say he was pissed). I can only wonder what would happen to a chainsaw and operator if this might happen.

Take care.

Well........ Great tip about the bushing, didn't like it when I put it together.. As for the carbides coming off, the blade is rated for 6000 rpm, don't think the old saw is set that fast. Didn't experience any kickback, but then again it was a small stump and I was being DAMMED CAREFUL! Had the saw on the ground rotating it around on one corner of the wrap, kind of on a 45degree angle to the stump, just taking little bites, a lot like a small version of the vermeer we have at work (other than the angle). NOT something I'd do very often. If I had much to do I'd get a proper stumper!

The carbide comes off not so much due to the speed, but gets broken by shock loads. Even demo blades for 7 1/4 saws have "blunt" teeth and large shoulders behind them to support the carbide.

277v hurts.

Hail, I remember when I was felling some bigger stuff, I think it was 45000V ... taint nothin some rubber boots won't stop!

I've used a few chains for rocks at work before. Unfortunatly they don't do too well afterwards, the chains that is.
