Chainsaw question

PitbullMidwest · Nov 8, 2001

Has anyone ever watched the Stihl Chainsaw Challenge on ESPN?

I saw a show last Saturday, individual and team competition where they cut 18" white pine logs with chainsaws, single and double buck saws and axes. The last event was the "power saw", custom chainsaws run by snowmobile engines. They had to make three cuts through the 18" log and they did it in under 10 seconds! My 7 year old thought it was the coolest thing he had ever seen (dad thought it was pretty cool too.)

Anyone else seen this show?

Just curious...Do all of you have and wear the helmet and chaps? Except for tree trimmers (and not many of them), I don't think I've ever seen people wearing them.

Also, the sprocket (wrong term? the one connected to the engine) on my saw has a groove the whole way around it where the chain runs. When should the sprocket be replaced?

Stihl had a challenge demo set up at the Farm Progress Show. It was very cool. Big crowd, but I was still able to stand fairly close. Those saws must be razor sharp /w3tcompact/icons/smile.gif

I have two sets of chainsaw chaps, both given to me for Christmas presents the same year. They are a good measure of protection for a small investment when you consider the alternetives.

The hard hat with ear protection is NOT an option as far as I am concerned. I used to cut without one until the day I was cutting down a large maple tree with a few dead branches 20 feet or so up. Just the vibration from cutting the base of the tree caused one of the branches directly above me to fall. The branch, about an inch in diameter came straight down with the big end hitting me on the shoulder missing my head or neck by only inches.

Right then I decided the $50.00 for the helmet was a better deal than a dent in the head, or worse. I know what it felt like to have the branch hit my shoulder. Since then the helmet has taken a few bumps I have not had to experience.

A good pair of leather boots will go a long way at protecting your feet. Gloves I think are more of a personal preference, I feel I get a better grip on the saw without them. There is one thing related to grip that will help protect you in a kick-back situation. If you keep your thumb wrapped around the top handle of the saw there is a greater chance you will be able to control the saw if it kicks back.

Youare,

Some good advice.

Long pants, leather shoes, and gloves. A must!!

Looks like I should invest in the chaps and headgear.

Oh, honey, I need to buy...../w3tcompact/icons/smile.gif

Hi ya
Before we got saterlight tv i saw the adds and thought i'll watch it but it has not been on in nz for a while,, i have seen the mother of chain saws built just for show speed cutting it was powered by a alloy 350 chev 2 guys had to hold it but good cutting saw ..ok tighting chains frist work out why ya chain is loose blunt,lack of oil,wrong oil,etc etc if ya don't fix that ya will shorten the life of ya chain..ok now let it cool undo the nuts and tighting chain ,now snaping of chain helps to pull kinks out and seats chain in bar (pulling out and letting go a few times)some say 1/8 between bar and chain other say pull's out till 1/3-1/4 of drive link still in bar .the trick is a cold chain should have no sag and freely move with low restance ie thumb and 1 finger will pull the chain around the bar if needing both hands too tight ,pull up bar while tighting nuts ,note chain should be tested for slack in same place ...ok someone asked about sprockets a rought rule of thumb is 1 bar =2-3 sprockets and a sprocket = 3-4 chains,another thing with chains is files are better than grinders for sharping but if not very good with files then the small 12V grinders are good to use and ya always have a sharp chain instead of haveing to take them to town ..

For me, I wear the helmet if falling trees. More than once, a limb from another tree will fall nearby where I am standing. Only once did I have one push my helmet down over my ears and made me see stars. But they were lucky stars, as without the helmet I would be seeing them from a different perspective.

The sprocket is what drives the chain. What has worked well for me for 30+ years, (and was recommended when I bought my first Stihl saw) was to buy two chains with a new sprocket, switch them at major sharpenings (also flip the bar over at the same time), and when the chains wore out (no more to sharpen) buy two new chains and a new sprocket. That way the sprocket will wear evenly, I guess, and keep pace with the wear on the two chains. I understand it is best not to put a new chain on a worn sprocket, as one will tear up the other quickly.

Mike, I think they sound like a good idea, but the fact is that I've never even seen any of the chaps and have never seen anyone wearing the helmets, except professional tree trimmers and they usually only have a hard hat and safety glasses. I suspect it's at least partly because the heat would kill you in all that gear around here in the summer./w3tcompact/icons/frown.gif
