I'm really curious as to what job you are doing that would require those properties. Anything flame retardant isn't going to be flame retardant once it's soaked in chain oil. Is this to protect against arc flash around big electrics? I can't see why anti static would be necessary. Are you felling inside an electronics lab? If it's for working around flammable vapours then your chainsaw is going to be a much bigger problem than your keks

Tree surgeons taking all the women Good old Daily Mash: "Researchers found that 82 per cent of the UK’s female population currently has feelings for trees surgeons, who are strong and brave but also know about nature. Professor Henry Brubaker of the Institute for Studies said: “‘Tree surgeon’ isn’t so much a real job as a contrived female fantasy."

al least you can roll the logs there!

I add tweezers, two eye wash pods and a small bottle of iodine to my personal kit.

The other day a mate of mine had to explain to someone who has a PhD in Physics why driving up Brassknocker Hill in Bath (1:10 with 100m vertical ascent) at 4mph in second gear slipping the clutch the whole way would "make the car smell like hot brakes"

I find my 181 is very fussy about stale fuel. It gets used very infrequently so if I buy a gallon of pump fuel I find even after about 3 weeks it won't run or will be an absolute c**t to start and I have to chuck half a gallon away. No problems since I switched to Aspen.

CS30 is the cross-cut and maintenance. CS31 is the felling.

Personally I think you'd be best off doing the full course. The home-owner thing is aimed at you cutting up some firewood on a saw horse in your back garden but with five acres of woods you'll need all the felling techniques etc from the full course. I found my CS30/31 course to be five days of genuinely useful training. I had no idea how much I didn't know until I was shown it. If you're looking to save some £££ then don't do the final day for assessment if you don't need your tickets.

Also the Moon would be 2.5mm in diameter and be 276 mm away from the Earth. you could fit about 30 of the international space station in the diameter of a human hair and they'd be 0.3mm off the surface of the earth. This is fun Massive thumbs up for doing this with your kids! More kids need to do fun stuff like this and realise science isn't about sitting in a classroom being bored. The thing that always makes me appreciate the scale of these things (and the fragility of the Earth) is the 'Pale Blue Dot' photo taken by Voyager from the edge of the solar system and Carl Sagan's description of it here: [ame] [/ame]

Neptune is 324m away so your road is long enough but is your eyesight good enough to see a 3.5mm planet at that distance?

The sun's diameter is 1,391,684,000 metres so our scale factor if the 'sun' is now 1m in diameter is 1/1,391,684,000 which is 0.000000000719 This means that Mercury will be 41 metres away and about 3.5mm in diameter. Venus will be 77.7 metres away and will be 8.7mm in diameter. Earth will be 107m away and will be 9.2mm in diameter. Just type distance from sun to Mars and diamer of Mars into google and multiply the value by 0.000000000719 to do the rest. n.b. don't forget to add an extra 3 zeros onto the 'real' numbers before you convert them so they are in m not km.

Thanks everyone. Lots of genuinely useful info there. I'll see what he wants to do. I'd lean towards having a crack at doing it in-situ with a hoover and a load of grease then blue roll on the piston. Quite interested in the flogging it on ebay and buying a new one plan though!

Hi All, A mate of mine has an MS180 that he says has just blown the spark plug out of the cylinder head. Is this worth bothering to fix given that a new MS181 is around £200? Presumably it will have to be stripped down into bits before the head can be drilled out and helicoiled? or is it possible to do it with the saw mostly assembled and blow the swarf out of the cylinder with an air line? Do you think it was running lean to have caused this and will it have damaged other things like the piston and bearings? Cheers.

beware that you get what you pay for... the cheap chinese crap will likely be poor quality LEDs which will fail before long or they will not even achieve their rated output when new. Like this guy who bought some from ebay to find that they are very dangerously wired up (they've used hot melt glue to attach the earth lead to the case FFS) and 10W LEDS sold as 20W EDIT: you get what you pay for but you also often end up paying premium price for dressed up chinese crap too! I have no useful advice as to how to avoid this
