I found a calculator for you for computing weight of logs: Log Weight Calculator at WOODWEB (imperial) It doesn't have Poplar, but you can use Aspen for similar density. Input: Species: Aspen, Quaking. Small End Diameter: 28 inches (my best guess at 70% of large end diameter). Large End Diameter: 40 inches (your 10'6" circumference divided by 3.14) Length: 32 ft Resulting estimated weight: 7979 lbs (which is 3620 kg). The metrically inclined can use this calculator: Log Weight Calculator at WOODWEB (metric)

Being from the continent, I have to convert everything to metric units before I can do any calculations (sorry). * 10'6" circumference = 3.2m, giving a diameter of (3.2/pi) = 1.02 m. * 32' height = 9.75 m * Fresh poplar density = 600 kg/m3 An easy formula for calculating the volume of a cylinder is (height*diameter*diameter*0.78). Total volume, assuming diameter of 1.02 through entire length = 8 m2 As it is likely that the circumference was measured at breast height, I would guess the actual volume to be about 30% less (which would assume a top diameter of 0.7 m) = 5.6 m3 In that case, the weight would be 5.6 * 600 kg = 3,360 kg.

The Distel Gecko's are without doubt the most comfortable spikes around, but that comfort comes at a price... Distel Gecko aluminium climbing spikes, leather straps | F R Jones and Son

Here is a previous thread about the TreeMotion Super Light harness: http://arbtalk.co.uk/forum/climbers-talk/57527-treemotion-super-light-harness.html
-
As above, except if you frequently climb old pine trees (thick, loose bark). The short (pole) spikes will often cause you to gaff out, so would recommend the long spikes in that case.

Here are a few earlier threads from this forum about this exact subject: http://arbtalk.co.uk/forum/chainsaws/65001-2-stroke-oil-fuel-ratio.html http://arbtalk.co.uk/forum/chainsaws/28661-50-1-vs-25-1-a.html http://arbtalk.co.uk/forum/chainsaws/29906-fuel-mixture-query.html

Use whatever mixture ratio recommended by the OIL. What oil are you using?

It's a Maasdam Rope Puller. Very handy and a lot lighter than my Tirfor winch. Rope Pullers & Cable Pullers for Tree Care Operations http://www.treestuff.com/store/catalog.asp?item=117

I wouldn't use beech for outdoor furniture. It will discolour within months and start to rot within a year. Use Oak, Cedar, Larch or Douglas Fir, or even Spruce/Fir/Pine which will all last considerably longer.

I have been using this home made ground anchor for pulling smaller trees with a 400 kg winch. It is made very simply from 2 meter chain and 7 pieces 10mm/70cm rebar stakes. Chain segments welded to end of stakes to ease pulling up and to assist holding down the chain. It will easily hold in excess of 400 kg pulling force. Total weight <5 kg. Total cost about £12.

* Negative (black) terminal to the tool. * Positive (red) terminal to the scrap metal. Lots of info on the web https://www.google.com/search?q=electrolytic+cleaning+tool+rust

Quite a few threads on here about this subject. Have a look at some of these: https://www.google.com/search?q=working+sweden+site%3Aarbtalk.co.uk

It is not easy to lengthen the RopeGrab when the lanyard is under load. For the ultimate (and sap tolerant) solution, mount an ART Positioner (with swivel) on a 13mm wirecore lanyard. Expensive but really comfortable. ART Positioner 2 with swivel | F R Jones and Son

The nerves to the little finger, and the little-finger side of the ring finger do not go through the carpal tunnel, and they are therefore not affected by a constriction of the tunnel ligaments.

Had the operation done four years ago to relieve the symptoms of Carpal Tunnel syndrome. It puts you out of action completely for two weeks, and you shouldn't do heavy work for two months. Symptoms are completely gone. Symptoms are: - Numbness/tingling sensation in the palm, thumb, index finger, middle finger, and thumb side of the ring finger. - Weak hand grip. You can reduce the symptoms a little by sleeping with the fingers stretched out (e.g. hand wedged between the mattress and the pillow). Pictures below: 1. During operation (taken with my mobile phone, local anesthetic). 2. Nine days after operation

Well, the OP specifically requested PN for Oregon, and that is what I referenced, so 5.5mm it is

Look it up on chainsawbars.co.uk Oregon chisel 3/8 .058 84 drive links (73LPX084E) or Oregon semi chisel 3/8 .058 84 drive links (73DPX084E) And as it is a 3/8" chain, you'll need a 5.5 mm (7/32") file

As Spud already said: Carb gauze filter might have become blocked. That would prevent fuel from getting into the carb.

Apple (iOS) or Android?

It could also be that some weak clutch springs made the chain creep, and the user applied the chain break to stop it. Or someone didn't know about the chain break (it happens), and tried to gun it, to make the chain move
-
It could also be the actual contact that has a bit of sawdust wedged inside it, preventing it from short-circuiting the ignition (which is how the stop switch works on all saws). In the meantime, you can stop the saw at any time by putting on the choke.

Hope he doesn't take exception to that comment
