Bore cutting without chain brake?

[mainer_in_ak]

On a job i just quoted, have a coupla cottonwoods that I measured at 32" diameter with my loggers tape. One has a heavy lean and will need to be bore cut. Only problem is the only saw I have on hand that will do a clean bore cut on such a large tree is a ported cs 1201 with 36" bar. This fkn thing has so much torque, it has snapped .404 chain. Chaps ain't stopping that thing if she spits the cut.

I feel a little stupid/scared bore cutting with a saw like that. It's like Jake Paul about to box mike tyson, and acting like everything is a-ok, because the tyson or the 1201 is an "old" design.

I keep getting images of the fkn thing spitting out of the cut and cutting my torso off my legs.

Anybody ever have issue bore cutting with .404 and no chain brake?

I've got a ported cs 8000 that I could get a 36" bar for. But I'm kinda limited on time to wait for the order to get to Alaska.

Start the cut with a smaller saw. A foot in and you should be ok

Well, think of all the leaners felled via bore cuts…before chain brakes were invented.

Well, think of all the leaners felled via bore cuts…before chain brakes were invented.

And of all the wooden legs...

Ported saws or not, a big lean, and no chainbrake... well, Id sooner be alive than make a few bucks..
...just sayin...

My experience with massive cottonwoods:
The closer to water they are, the heavier they get. These two are right beside a dmn creek.

They're brittle, so the hinge wood has to be a bit thicker. You can't just come out of a bore cut either, you have to bore cut only 1/3, then come in the the back side, leaving a second sliver of tension wood.

They're unpredictable. No matter how much u plan a cut, they don't cooperate.

I guess one guy showed up, frowned, shook his head, said he hates big cottonwoods, quoted the property owner $8000 and left.

Fk man, yep I'm not gonna bore cut with no chain brake on an uncontrollably powerful saw. I feel like an idiot even considering it. Now, bore cutting with a jumpy saw, I can CONTROL 81 cc. It's happened, stumping with the cs 8000 and all was well. I'm just gonna wait for a 36" bar that will fit the cs 8000.

Now that I've thought about it this morning, while drinking coffee:
Heavy, waterlogged cottonwoods tend to set down on yer fkn bar. Where it'll set down is on the top side of the bar as I plunge into my borecut, nearest the hingewood. The ported 1201 is the wrong mamba jamba .

If I was in my 20's I would've impatiently, mildlessly done this job with what i had on hand.

I'm in my fkn 40's, self preservation has prevailed.......

bore from 2 sides. you really need only 50cc saw and 16" bar for it

Nope. No way am I walking behind a leaning cottonwood to finish a borecut with a short bar.

 

[Woodwackr]

Had one sit down on 3 wedges...after I'd pulled out...wood just formed around the wedges...never seen that. Big excavator even had trouble pushing it. We finally gave up trying to get it to go in the optimum direction and let it go into a plowed field. 3' base Cottonwood.

Do you know the twisting the handlebars trick when bore cutting? I’m not suggesting trying it for the first time on a big tree with a big saw and no chain brake.

Be safe, we want to hear from you how the cut goes instead of from an obituary!

Could you lop off plenty of branches from the side its leaning towards, to help against the big lean problem then maybe it would be easier to just fell it in the usual way. Or if you can take enough weight off like this, then maybe you coukld fell it in a different direction. I have felled trees making 2 whole bore cuts, then shoving long logs through the bore holes and using a damn big jack to fell in the direction I wanted. But mainly I used a tractor mounted 10 ton winch... sometimes with blocks to increase the pulling tonnage, you need a w.m.d. proof hinge on stupidly awkward stuff. Even had tractor upside down one time. All good fun....

Hy sht gorilla! I found your theme song. Play it on a jobsite speaker next time you pick up a saw. And PLEASE film it, you'll be famous:

Ha Ha Brilliant.. cheers dude

Well, just to clarify a lot.. the government were paying for everything and time was irellevant. We did loads of tree surgery, and so climbing and chopping bits or lots off here and there was just a bit of a daily challenge. We could do just about what ever we fancied. there was a hardcore off road motorcycle track on part of our patch, naturally.. they gave us land-rovers for our off-road work, and well.. the winch tractor was used a fair bit recovering the vehicles from there. Best job I ever had.

 

[gorilla]

Did I mention the ice cracking on the frozen lake when we were sent to recover some debris... Land rover again...
Or when we used an inflatable dhingy.. we named the TITANIC doing much the same thing, what a laugh..

Finally finished that clearcut job. I ended up finding a cheap/used 36" bar and a $29 116 dl loop of older 3/8 lgx.

On the ported cs 8000, plunged right in with the 36" bar. I left the rakers alone as it was a brand new chain and I wasn't sure if the saw could pull it. The old lgx was very smooth in the bore cut.

I stayed low, near the base as the grain is more stringy and stronger. I kept the hinge wood 2.5" thick.

Cleared out what could barber chair then pulled out of the bore cut.

Came into the back cut to thin down the that secondary sliver of hinge wood. Tree came down fast. Felt like a small earthquake when she hit the ground.

New-found appreciation for my ported 81 cc echo. She pulls 36" full house 3/8 no problem.

Needed a 42" bar on the cs 1201, to mill one of the three big cottonwoods.

The straighter cottonwoods had rot and sure were heavy. I needed multiple wedges and beat my shoulders out of socket to get them to budge.

Mad respect to you!
