Trimming broken limbs
I need to trim off some broken limbs 8-10 inches in diameter that broke off from the wind last week. I can handle the lower ones with my reciprocating saw. What's the best way to attack the ones 8-10 feet off the ground? I want to stay away from pole saws and chain saws.
I'm thinking about fastening my recip saw to a piece of 2x2 aluminum angle aluminum. I'm a metal fab guy, and by I mean bolted and supported properly with metal brackets, not fastened with duct tape. But I would rather have something specifically made for occasional homeowner use on limbs. Anyway, any other ideas besides these that you have used for occasional homeowner trimming? |

I just climb up and use chain saw wearing goggles. I have nothing to worry below from falling limbs. |

But I would rather have something specifically made for occasional homeowner use on limbs. Anyway, any other ideas besides these that you have used for occasional homeowner trimming? There are basically three "remote" options: - manual pole saw (i.e., a regular saw on the end of a long pole) - a small (typ electric) motorized saw on the end of a long pole - a remotely driven (motor at the user end of the pole) chain saw All suffer from the "remoteness" aspect -- you're trying to position and control a cutting element many feet distant from your "actuators" (arms). All also suffer from a typical naivite of operation that typically leads to "torn" limbs or "collateral damage" (from the saw's continued, but undesired, action after the limb has been severed). The "motorized saw on pole" is often unwieldy -- too much mass on too long of a lever arm. I suspect your sawzall-on-a-pole would suffer a similar fate. Your arms get REALLY tired, REALLY fast when working above your head/shoulders. For small limbs, I like a manual pole saw as I can be much more precise in the amount of "damage" I do to the living tree in the process. For large limbs, an OVERLY LONG motorized trimmer (so I can hold the bulk of the weight down at waist level instead of overhead). For really high limbs, I hire a monkey to do the work for me. (there are other, safer, ways I can save money than climbing a large tree just to lop off a branch!) |

The electric pole mounted chain saw I bought from Princess Auto for $70 a number of years back was one of the best tool purchaces I ever made. A ricip on the end of a 2X2 aluminum angle is just an accident impatient to happen. They jump around enough when held close to the body with 2 hands. |

I would rethink the pole saw. The one I have uses a detachable electric saw that is also handy for cutting up the stuff you drop. |

I can handle the lower ones with my reciprocating saw. What's the best way to attack the ones 8-10 feet off the ground? I I had a whole tree like that a couple summers ago. It was still attached at the ground, but 25 feet of trunk went over my back yard, about 8 to 9 feet high. want to stay away from pole saws and chain saws. Well sure. I only owned a small electric chain saw because one was for sale at a yard sale, but I've used it a lot. They're now designed so both hands have to be where they are safe, and if you put safe holding first, and safe climing the ladder a step or two second, I don't think you'll have more trouble than I did. I spent quite some time deciding where to cut first, so when cut one half of the trunk wouldn't spring up out of my reach, and the other half wouldn't fall down on my bushes. I have an aluminum 6' step ladder and only had to go up two steps if I also held the saw above my head. 4 steps, I could have held the saw straight out, but the first choice seemed better. If I had someone to hold the ladder, maybe it woudl have been the second choice. . I'm thinking about fastening my recip saw to a piece of 2x2 aluminum angle aluminum. I'm a metal fab guy, and by I mean bolted and supported properly with metal brackets, not fastened with duct tape. But I would rather have something specifically made for occasional homeowner use on limbs. The saw I happened to buy is one size larger than the one that comes with a pole attachment. In fact the handles are the same and I could attach this one to a pole, but I don't own the pole and it would really be too heavy as Don writes below. I did borrow it once from the friend of a friend, so that's how I know. Anyway, any other ideas besides these that you have used for occasional homeowner trimming? There are basically three "remote" options: - manual pole saw (i.e., a regular saw on the end of a long pole) - a small (typ electric) motorized saw on the end of a long pole - a remotely driven (motor at the user end of the pole) chain saw All suffer from the "remoteness" aspect -- you're trying to position and control a cutting element many feet distant from your "actuators" (arms).

The "motorized saw on pole" is often unwieldy -- too much mass on too long of a lever arm. I suspect your sawzall-on-a-pole would suffer a similar fate. Your arms get REALLY tired, REALLY fast when working above your head/shoulders. Not only that, but I woudlnt' be surprised if the blade stops in the wood and the rest of the saw goes back and forth instead. Since a chain saw goes only in one direction, pulling the saw away from you, you just have to hold it back and it cuts. For small limbs, I like a manual pole saw as I can be much more precise in the amount of "damage" I do to the living tree in the process. Of course his limbs are already broken off. For large limbs, an OVERLY LONG motorized trimmer (so I can hold the bulk of the weight down at waist level instead of overhead). |

Maybe philo woudln't like that either. with a ten-foot ladder, I definitely would have climbed higher and held the saw straight out. The OP doesn't need a pole saw if they are only 8 to 10 feet high, unless he has no ladder at all. I heard of someone killing themselves. |

It took me several days to do it all, though. -- Maggie My wife took out about 100 square feet of Brazilian Peppers with her electric chain saw.

I've learned a lot about cutting trees since I started heating with wood . I attach a rope or chain as high as I can get , tie the other end to a cable hoist or block and tackle that's attached to the bottom of another tree . Put tension on the tree towards where you want it to fall and put a notch 1/3 to 1/2 way thru on that side . Cut straight across from the notch , tightening your pull as you get deeper into the cut . I've had a couple that didn't fall exactly where I wanted them , but most land within a foot or so of the target area . My biggest problem has been the trees hanging up on other trees on the way down . I've got a couple that need to come down where I'm going to build our bedroom , shoulda taken them before I built the living room ... -- Snag |

Then when I'm done, I'll still have a drone and a laser. Hey, I just made this up but it seems I'm not the first. http://www.laserfocusworld.com/artic...a-in-1965.html "Tree felling with lasers: a big idea in 1965 03/01/2005 But some ideas, such as tree felling with lasers, never materialized. Although scientists seemed to understand that tree felling was not a practical application for lasers, that didn’t stop the visionaries of the day from telling the world about the ominous potential for laser tree-cutting technology at the 1964/1965 World’s Fair." Of course this article was written 10 years ago. If they have brighter LEDs now, maybe they have sharper lasers. "Woodworking, not tree cutting While it was first reported in the Feb. 15, 1965, issue of Laser Focus that felling trees with lasers was being researched by the University of Michigan and the U. S. Forest Products Laboratory in Madison, WI, a later story in the April 1 issue, “Woodworking-not tree felling-laser’s forte,” retracted the finding. The article noted that investigation into the report had, however, unearthed an interesting paper resulting from research done two years earlier by the same principals.1 Apparently, Norman C. Franz of the University of Michigan’s Department of Wood Science and Technology confirmed that tree felling was only an idea. “Equipment is not available at this time to even research such a project,” he said. Instead, the research subjected wood samples with a range of densities to repeated laser pulses of less than 1-ms duration from a ruby laser with a maximum energy output of 3 J per pulse. Although depth of penetration was less than 1/16 in. per pulse for a 0.03-in.-diameter hole, it was concluded that the laser could be a practical wood-machining tool if a high-power, continuous-beam, more-economical laser system could be developed. " got the lift for free because the club my wife works for had it all week and we used it off hours. The dumpster was $350 Next time your wife's club gets one, let me know. Hmmm. I have a friend of a friend with a bucket truck, but this tree is not close enough to the street; I'd probably have to drive on a lot of sidewalk and I'd break a bunch of that. "Tree-felling idea dies hard Despite the reduced ambitions of the scientific community in applying lasers to tree cutting, Laser Focus magazine ran a story in the May 15, 1965, issue, “World’s fair exhibit projects laser tree-clearing machine.” It seems that the technological visionaries for the General Motors Futurama exhibit at the 1964/1965 World’s Fair in New York City were not ready to let the idea die: in their “ride into tomorrow” exhibit, an insect-like laser tree cutter, designed to saw off trees at their base (see figure) preceded a massive jungle road-builder that was envisioned to make an express highway through densely wooded forests in one continuous operation. The visionaries cannot be faulted for wanting to apply laser technology to tree cutting; they can only be faulted for not anticipating the high cost associated with high-power lasers. Despite the ability of today’s CO2 lasers to slice through 1/2-in.-thick wood at 85 in. per minute, their multiple-thousand-dollar price tag still cannot compete with a $200 chainsaw. Cutting more than trees The ultimate display of the power of today’s lasers is exemplified by the Pentagon’s Airborne Laser weapons system-a bank of chemical oxygen-iodine laser modules boasting multimegawatt power levels (see Laser Focus World, July 2004, p. 15). Back here on Earth, lasers for cutting and machining continue to improve in performance and decrease in price. The ruby laser used in those early wood-machining experiments is now joined by high-power CO2 lasers with nitrogen and oxygen assist, solid-state lamp- and diode-pumped lasers, Nd:YAG, and excimer lasers, as well as emerging femtosecond Ti:sapphire lasers. Today, a 4-kW CO2 laser with oxygen assist can cut 12-mm-thick carbon steel at 60 in. per minute.2 With power levels exceeding 5 kW, solid-state lamp- and diode-pumped lasers, along with CO2 lasers, are the primary types of lasers used in industrial machining and materials-processing (see Optoelectronics Report, Jan. 1, 2005, p. 4). However, femtosecond lasers, first reported to have exceeded the 1-pW power threshold by Lawrence Livermore National Laboratories (Livermore, CA) in 1996 (see Laser Focus World, July 1996, p. 13), may eventually surpass other laser types for some machining and cutting applications. While the price of femtosecond lasers is still prohibitive for most industrial uses, solid-state and CO2 lasers with power levels sufficient for cutting wood have significantly decreased in cost. If costs and corresponding market prices continue to fall, perhaps tree felling with lasers will again be a big idea in, say, 2025? ?" Another problem is that they were cutting at ground level. I want my first cut to be about 30 feet high. Although maybe I cut lift it up there with a drone. They didn't have drones back then. Doesn't Woodcutter Barbie come complete with its own laser tree cutter and dreamhouse? |

I had a 40-ft Mexican date palm cut down - mostly one long trunk. Trimmer climbed up and cut it down in 2-ft pieces, which I kept and used to build a make-shift retaining wall / plant stands. |

I've never seen a Ficus that big at a typical home property. I know if they get water they grow like mad. Next to a sewer septic line / field or near a natural spring. It is pretty wet back there and the water table is about 4 feet down. They are related to the Banyan trees. Ever see the one at the old Lee county courthouse? Many times. I used to be downtown several times a week. My neighbor has a banyan and it is a weed too. There is a very old picture of the "hanging judge", he tossed a rope over the banyan tree branch at the court house. Shown in the Ft Myers News Press. He used the photo for his election. (tough on crime) The name escapes me right now. Circa 60's. You didn't want to appear in his court :-) Would that have been Judge Hyram Bryant? |

I dont have it handy to look at the amps it uses. It's a Remington brand. If you got one from HF, it's good you returned it. It would probably be in the garbage by now. HF electrical stuff is pure trash! (Just my opinion, based on past purchases of the crap). |

Trimming broken limbs
"Snuffy "Hub Cap" McKinney" wrote in message ...
I need to trim off some broken limbs 8-10 inches in diameter that broke off from the wind last week. I can handle the lower ones with my reciprocating saw. What's the best way to attack the ones 8-10 feet off the ground? I want to stay away from pole saws and chain saws. I'm thinking about fastening my recip saw to a piece of 2x2 aluminum angle aluminum. I'm a metal fab guy, and by I mean bolted and supported properly with metal brackets, not fastened with duct tape. But I would rather have something specifically made for occasional homeowner use on limbs. Anyway, any other ideas besides these that you have used for occasional homeowner trimming? === Well, I got the trimming done with my old Harbor Freight recipicating saw and a 12-inch blade. Fastened it securely to an 8-ft 2x2, with the cord unplugged I locked the swich "on" and ran the cord down the side. Then I rested the body on the limb I was going to cut, plugged it and then set the blade down on the limb and let its weight do the work with no twisting or trying to rush it. While cutting I always kept the extension cord in one hand so I could unplug it quickly if needed. Just before the limb was cut through, I pulled the extension cord loose and sawed back and forth by hand. No binding, kicking, etc. No close callls. I'm always way too cautious and if something is not going right, I bail out and start a different way or just stop. I spent a lot of time trimming all around the bigger limbs to be sure they would fall straight down and not bounce toward me or the wrong direction. With one limb I tied it to another tree to be sure it fell away from of some plants which I had been giving specific instructions not to step on. Even after doing this fine, hiring a tree-trimming is the best way to go. I'm not recommending anyone else do what I did on account of I don't know your skill level. If you are not familiar with tree limbs & power tools I definitely would not do any tree trimming. Will try to upload a few pictures later. |
