Best Notch Cut

[dbabcock]

Russ,
The stuff in the picture is used for characterization of integrated circuits. That's why you see the binocular microscope head. The IC's characterized here contain very high speed LINEAR or analog circuits which, unlike the binary (1's and 0's) nature of computers, operate in modes which offer a continuously variable characteristic. A good analogy would be that a computer type circuit is like an on/off light switch and a linear circuit is like a dimmer light control. Everything we experience and interact with in life is fundamentally analog in nature, namely, varying degrees rather than absolutes. Computers make doing many things easier, but in the end we live in an analog world so we must somehow convert the analog things that we understand into and out of the binary world of computers.

When I tell people that I design IC's for a living, 99% come back with a statement such as, "Oh, you design computer chips", or something of that nature. At that point I just nod my head and agree with them.

Hey Doug, how long have you been designing computer chips?
John

 

[dbabcock]

Never designed a computer chip in my life. If you mean IC's, then the answer is: longer than you've been a logger. Hmm Hmm Haa Haa.

Rob, thanks for the advice . You should have been here a couple years ago when it was really windy. These giant evergreen(3 ft diameter) were falling over. It take about 3 seconds . Very surreal. The wind did not seem worse than a normal storm. There is a bunch of trees that fell down 30-40 years ago and i always assumed it had to be hurricane.

Fiber Cost

Doug let me know when you need more patch cables, I can beat that price of 500 beans. I have been running alot of gb network lines the last few weeks and tons of fiber.

As for the Cisco kid learn Linux "squid servers" less overhead and tons of power in an IDE box. I have my Cisco Cert but love working with the 2.0 kernel. Here's a job I did a few months ago all Cisco with 2 T3 as the Back Bone.

 

[dbabcock]

Hey Mark,

It's coaxial cable, not fiber. Sorry about the confusion.

Isn't it great how we can work in this OT nonsense as long as the thread title has something to do with chainsaws? My next thread title is going to be: "Mapping 385XP Transfer Port Flow: A Finite Element Approach".

Trying to build a linux box right now. The project is on hold right now because the budget is dry. Sytem is going to be a Pent. II 233 mhz processor, Ram ???. havent ben able to power it up to see what the BIOS says. would have replied sooner but school keeps me busy and have also been sick the past few days. well better go. my medicine is kicking in and starting to see double from drowsiness

Into my 6th year now of running Linux exclusively.  The gateway/DNS/NAT/etc. box here is a P-166 w/32MB RAM. I've been waiting to put more RAM in it so I can run squid, but first I was waiting for a year of uptime, now I'm waiting for the uptime counter to roll over at 497 days.  That'll be in about 30 days 2 hours.  This box is a P-II 233 and I think this instance of netscape has been running now for a couple of months anyway.  Wouldn't touch Microsoft crap with a 100 ft. pole.

Gotta say I love my 036 (to get a little on topic).

linux Notch

Linux go www.astaro.com download and burn the iso for your VPN and anti virus don't worry about the pII just load up on the ram. You can take Celeron 1GHZ and run a file server on that.I will start a thread on the Off Topic and post some of the machines I have been building. Nextweek I have to go to the Hospital and get operated on so I will have sometime to post more overthere. Also make some phonecalls I have been blowing off.

I have been running linux for sometime and you know it never fails, at our shop we sell windoz but that's were the loot is for workstations. Anther site is www.linuxfromscratch.org you can put your own OS together.


I have to keep this on the topic of notches if Doug gets that 200 acres underway I would like to see Rob's Skidder :Monkey: at the staging area. By the way Gypo what is a staging area when you are logging?

John did you get my email?

 

[StIhL MaGnUm]

Man and I thought me and Willock got off topic here we have a coaxial cable open face humboldt plunge cut notch the highest tech of them all ...

Later Rob..

I was hoping to hear more about that fancy notch Gypo'd used up there in his <a href="http://www.arboristsite.com/attachment.php?s=&postid=63314">357xpgg beech.jpg</a>.

I think I could fairly well duplicate either of the two subjects of the poll in this thread starter, but that one in the beech looks to be a bit beyond my capabilities to pull off.

 

[Gypo Logger]

Hi Glen, I think that picture is my best yet, even if I do say so myself. Although it looked bigger because of the snow, it was about 28" where I was cutting it off. It obviously was a blow down. The 357 blasted thru uncomplainingly. It isnt necessary to cut completely thru this type of wood, since you can snap the remaining holding wood with the winch, or simply bunt it with the dozer blade on the skidder. It will make some nice firewood.
Anywho, gotta make some finishing touches on this woodlot. I will make some nice trails that go thru the woodlot, so I better go and put in my 2 hrs.
John

 

[dbabcock]

Man, you're getting close to getting the hang of the DOF thing, John. We can talk about this picture tonight. Good work.

 

[glens]

John, I have the advantage of "knowing" you a bit by having lurked here for a couple of weeks before registering.&nbsp; (In fact, if a "best of" forum gets created as is being discussed elsewhere, it might piss me off a little.&nbsp; It's taken me that much time to get even marginally up to speed with what's been going on here.)

I was being a bit smartassical about the beech "notch".

That tree looks and sounds to be about the same size as one I was able to take last year. (I've still got somewhat less than a cord of it in my Indiana hardwood smorgasbord right now, just waiting for winter to actually arrive.)&nbsp; It was healthy and solid but the one in your photo appears to be not quite so, as beech is wont to become well before it volunteers to quit standing in these parts.

The photo is nice. &nbsp;I don't know what kind of gear you got, but it might have been nice to get another with that same depth of field yet focused on the plane of the saw.&nbsp; I'd probably stick the saw, lock the focus and set the timer on the camera, and run back.&nbsp; Sometimes those things are a little difficult to pull off alone, though.

I hear you about "putting in my 2 hours", I'm (somewhat less successfully, lately) self-unemployed too.

Hi Doug, thankyou for helping with my pictures. If I get one good one out of ten then I think Im doing ok. I cant wait to get the D1.
Glen, if I was more creative, I would take these sort of marginal stems and mill them. The best figured grain comes from highly stessed trees during various stages of decomposition.

Sorry Doug, I forgot to mention that I did build two transistor bistable vibrators in 1969. In case you dont know what I am refering to, this is the fundamental building block of all computer circuits. Judging by your supposed credentials Doug, may I suggest that I dont think that your elevator goes completely to the top.
John

 

[dbabcock]

Well John, if you built two transistor bistable MULTIvibrators, I might take you seriously, but unfortunately, any idiot can build vibrators with a battery powered motor, an offset weight and ZERO transistors. At least get your terminology right. You been surfing the net with Beavergirl again? "Your" the one who's one french fry short of a happy meal.

i prefer coming center apex on back cut to wide face; i can see where Willock might be trying to preserve wood and or/ save making a stump cut and getting stump free without leverage, and might not be able to make as wide a face realistically.

i prefer being in more of a ready to move position than crouched on the ground as Willock. But lower also maximizes leveraged pull on hinge, a slow cut forces this more power will show as power in hinge and not speed in hinge. Giving stronger forced hinge with lil extra weight. This lower cut can also give more leverage to a slight head leaner, making more assurance of direction.

The Lambert, could be open face for farther possible travel on hinge, unless shorter travel/control is desired. It comes deeper than the widest part of the tree, sacrificing some directional control by forsaking most leveraged path and position of fibers agains leans perpendicular to the fall. If a slight head leaner, can give more leverage at given height of cut by coming in this deep, to change lean angle pivot more to the rear, accessing more of the lean's potential leverage of length. ~Possibly taking a more forward hinge that would show a slight backlean in tree compared to it, and moving the hinge deeper like this, and now the Center of Balance is leaning forward (toward target) from hinge, where it would have fallen back from the other hinge. Or at not such a slight angle, but more easily to fight head wind etc.

So, in specific circumstances i would use either.

Crossing, kerfing the face cuts can cause dutchman type pushes in the face from it closing early across it's length or on one side. The most innermost hinge with shortest sweep will command most, even if it is a kerf cut. i think that bringing the bottom face cut farther than the top gives more of this effect and is more predisposed to barberchairing by design.

i assume an imbalance perpendicular to the fall and look for it and how to equalize it in all cuts felling, bucking, climbing, rigging, many times with tapered hinge, fat against lean/ downward pull. For extra help, i will bring towards a swing dutchy, by adding to the fat hinge against the lean, a dutch step under the lean to push off against the lean toward the hinges fatside pull, also moving back the compressed pivot part of hinge for more leverage slightly. i'll do this by placing a slight kerf under the lean side on the front face of the hinge, and preserve hinge pressing into that step purposely on the back cut. So, do beleive that some light dutching is safe and helpful; but beleive most are made accidentally from improperly/non inspected faces.


Orrrrrrrrrr something like that!
:alien:

 

[chainsawworld]

sorry i got here late. i have been dealing with many personal situations. as soon as i can i will read all replies. for the time being, neither knotch are by any means safe. marty

Aspirations are a wonderful thing, but keep in mind that while toys are great to have they are not what really makes life worth living.

B.S. total B.S, toys are everything!!!
