I'm after a chainsaw. They span from £50 Titan to a lot more for Makitas. What should I look for? Are Titans good enough for occasional jobs? It won't get used a lot. 16" bar needed, or more.

When used for pruning when up a ladder, there is a lot be said for an electric one IMO, essentially because motorised chainsaws can be a pain in the arse to start while up a ladder if they stall unless they are easy to start by sort of flinging it away from you. Not a very good description but can't think of a better way to describe it. Electric chainsaws are also a lot less hassle maintenance wise, but are pretty useless if you mostly use them away from home to cut firewood for burning etc. Are Titans good enough for occasional jobs? It won't get used a lot. 16" bar needed, or more. Sounds like you mostly want to use it for cutting down trees. |

Daughter does a bit of chainsaw carving: https://dl.dropboxusercontent.com/u/5772409/Carving.jpg and at one Arb show where she was asked to put on some form carving demo they weren't allowed to run petrol powered saws. ;-( They were allowed to run generators (go figure) so used a 29 electric saw I'd picked up on special from B&Q to do some basic stuff and whilst she said it worked, it wasn't like her little Stihl 171. But to be fair, carving is a fairly specialised role. IOO, there seems to be as much rivalry between the Husqvarna and Stihl owners as there is Ford and Vauxhall etc. ;-) Cheers, T i m |

I'm also looking at making a frame/holder for it to slice up wood relatively accurately. Looking to make lots of small pieces that will end up on show hence not ripping off edges would be of value, if such is possible with a chainsaw. NT |

I think that may depend (as with any saw cut) if you can support the wood as you cut though, although with a sharp enough blade it may cut it fast enough not to tear the last bit. Cheers, T i m |

Cheers, T i m I had one for a few years until the engine failed. The place I had bought is six years previously had gone out of business so I went elsewhere who sold me a saw which lasted over 15 years of fairly heavy winter usage until the plastic failed body parts failed catastrophically. They then sold me an Efco. They said the Stihl had died because I believed Stihl that their brand of two-stroke oil only needed to be used at 50:1 instead of 25:1. So I won't buy another one.

I guess what I'm asking at this point is whether we'll run into trouble doing this with a £50 Titan. I expect it's what we'll get for now. It might do a day or 2 of chopping once a month. NT |

They said the Stihl had died because I believed Stihl that their brand of two-stroke oil only needed to be used at 50:1 instead of 25:1. I'm not sure about the Stihl brand oil thing but using it at 25:1 could easily be a reason it died. So I won't buy another one.

Nothing is going to spin tree trunks any day soon, no matter how much it tries. I'm not sure you mentioned the size of wood being cut before now? The first one is a couple of tonnes. Others will be all sorts of sizes, mostly smaller. It's the saw that will be put in a frame to operate like a chop saw. So not the way you might normally cut though 'a trunk' using the bumper spikes / dogs as a lever? The trunks will be on the ground at all time - or maybe a couple of inches off it. The resulting restraint of the saw must make it much safer I'd think. If the trunks were in a 'V' or up against something in your frame that might resist the more cylindrical ones rolling back then it might work (to be safer than a hand held saw doing the same). they can't roll back. I guess what I'm asking at this point is whether we'll run into trouble doing this with a £50 Titan. I expect it's what we'll get for now. It might do a day or 2 of chopping once a month. As long as you aren't putting any extra strain on the cheaper saw (that a more 'industrial saw might deal with better) then no, I can't see any reason why it wouldn't do what you want, especially if the 'day or two's worth aren't 8 hours continuous use (as the cheaper saws might not be rated for that (as has been mentioned elsewhere)). Well, it will be 8 hours straight, less a lunch break. Maybe a cheap Titan won't be upto that then. NT |

Your engine will now run leaner, and youll have to make jetting changes." I was thinking - bull****. You've gone from a 95% petrol mix (5% oil, 1/20th) to 98% petrol mix (2% oil, 1/50th). No way are they jetted that accurately. But I read the article. The crucial part is that the oil thickens the mix, so it doesn't go through the jet as well. Which might also indicate that re-jetting for a different _type_ of oil, not just mix ratio, may be needed. Andy |

Yup, and now the fuel to air ratio goes up, the engine runs lean and (contrary to what most might think would happen), it runs hot (lean) and heat seizes or melts a hole in the piston etc. Which might also indicate that re-jetting for a different _type_ of oil, not just mix ratio, may be needed. Yup, especially if you are looking for optimal performance and / or reliability. However, ITRW and when talking about 'everyday engines' you can often get away with a lot but sometimes it can all add up. ;-( FWIW my old British Seagull outboard motor used to run on a 10:1 fuel / oil mix but is was *designed* to. Cheers, T i m p.s. And I wonder how much of Stihl's 'recommendation' to use 25:1 if not using their own oil might be to make the cost difference such that people simply don't bother to use alternatives? Do we think Stihl 2/ oil is that much better than the equivalent competitors oil that couldn't also be used at 50:1? Is that the original meaning of the term 'Snake Oil'? |

Inevitably it will end up being used in climbing too, but primarily ground work. I'm also looking at making a frame/holder for it to slice up wood relatively accurately. My safety training told us that was very dangerous with a chain saw. Jonathan Which, using saw whilst up a tree or using saw with a frame to hold wood? Using a frame to hold wood. There is a tendancy for the saw to catch and spin the log dangerously. Much safer to sut it on the ground, if worse for your back. jonathan There's misunderstanding somewhere in all this. Nothing is going to spin tree trunks any day soon, no matter how much it tries. It's the saw that will be put in a frame to operate like a chop saw. The trunks will be on the ground at all time - or maybe a couple of inches off it. The resulting restraint of the saw must make it much safer I'd think. There are plenty of "chainsaw mill" type attachments that allow you to use one for producing accurate planks and slices etc. I guess what I'm asking at this point is whether we'll run into trouble doing this with a £50 Titan. I expect it's what we'll get for now. It might do a day or 2 of chopping once a month. You may need to get it some decent quality chains (and a set of files for sharpening) -- Cheers, John. /================================================== ===============\ | Internode Ltd - http://www.internode.co.uk | |-----------------------------------------------------------------| | John Rumm - john(at)internode(dot)co(dot)uk | \================================================= ================/ |

Inevitably it will end up being used in climbing too, but primarily ground work. Saws designed for climbing are usually small light "top handled" designs, rather than the traditional layout with a top and rear handle. They tend to be fairly specialist and aimed at the pro arb market. (some dealers are also reluctant to sell them to people who can't produce the relevant training certificate for them). I am not sure I would fancy climbing with a normal electric saw. -- Cheers, John. /================================================== ===============\ | Internode Ltd - http://www.internode.co.uk | |-----------------------------------------------------------------| | John Rumm - john(at)internode(dot)co(dot)uk | \================================================= ================/ |

As with everythng else you might need at the top of a ladder you tie a rope around it and just take the rope(s) up with you and pull them up afterwards. Small stuff in a bucket etc. All of which can also have loops to hang it from branches or hooks The beauty of small battery drills which fit in a pocket is that its possible to screw in as many hooks as you think you might need rather than rely on branches to hang stuff from. michael adams .... |

Not really advised to drill holes in live trees or work from a ladder (especially if the ladder isn't roped in etc). They don't often 'spike' up a tree that they aren't going to cut down for the same reason (risk of infection to the tree etc). Cheers, T i m |

Speaking only for myself if somebody can't handle a saw chain without cutting their hands to ribbons then they maybe shouldn't be allowed near chainsaws in the first place. Assuming they can ever get the thing on in the first place, wearing these "thick protective gloves". So what do you think ? michael adams .... |

The theory is fine but in real life it makes almost no difference to the mixture at all, I have tested this on a Dyno with a villiers starmaker engine, cyl head temp/spark plug temp and plug colour. 2T Lubrication is marginal at the best of time this from your link is proven fact based and not EU eco emissions 50:1 ******** All the major manufacturers produce two-stroke racing engines in their off- road motorcycles. Virtually all of them recommended 20:1 or 24:1 mix ratios. 3. A second test they performed was to run synthetic in two identical engines and one was run at 24:1, the other was run at 50:1 The engine that ran 24:1 had less piston skirt wear, and less rod bearing wear, but had the same main roller bearing wear as the engine run at 50:1. - |
