    cutting blow down & snags that are hung up is even more tricky than falling cuz now you got a tree half assed down and you can't just leave it like that especaily on a ski run or bike trail, so things could go a lot of ways

    Wedges are a big help so I always have a hatchet on my belt & 2 wedges in my cruiser vest

    cuz if you don't carry the stuff on you, instead of doing the right thing you will try and fudgeit

    and yes you are going to die ... but hopefully later than sooner

    That butt log averaged maybe 2' in length. The 90 ton crane's load cell said it weighed about 6500 lb..... In the spring redwood can weigh close to 70 lb per cubic foot, meaning is heavier than most US woods, save live oak!!

    Very cool. Canít imagine swinging a 72Ē bar. Good to see you back on here. Very curious what a job like that costs roughly?

    If you are doing a lot of blow down- look up the fence posting technique for hung up trees- life saver (life prolonger?)

    I'm not messing around with anything too big. I'll just go around.

    Yes! The Humboldt undercut, my personal standard. However, it would have been a lot cooler if they’d spelled “Humboldt” correctly.

    the technique I was thinking of was basically this:

    Although I was taught to take the bind first - then do the undercut in a way that will allow the tree to come down in a controlled manner

    in my brief experience, i find a lot more tension / compression (high energy) in blowdown than trees that get hung-up. I slowly work to ease the tension/compression. I'm getting better at not pinching my bar. I get tricked about where the compression is on occasion.

    Alder and maple you gotta watch your ass. Honestly, I would leave both to a pro. You need long bars (get as far away from the tree as possible), big and fast saws, and a fucking sharp full skip chain for equipment, and a whole lot of skill with a bit of a willingness to die.

    Cut a bunch of blowdowns today. This thread has really elevated my still very low skillset.

    This one is fucked. I just hope it falls...and not on anyone. Right next to a trail.

    That last picture: hard to tell from the photo, but Iíd consider getting a rope around it and pulling down, perhaps with a simple rope come-along pulley system thatíd allow the puller(s) some leverage and the ability to be out of harms way.

    Yeah, it's a tough one. I thought about what you mentioned and it could probably be done, but I would want help with that. Was hard to get a pic with any sense of scale. To the right there is two main branches compressed up against another tree. I think ideally is climb the thing and cut from up top. Not something I can do though.

    Understood. Hard to tell from a single photo. It looks like a pretty big limb.

    The chainsaw thread...

    Anyone use their chainsaw to cut rough timber to use on mountain bike features? What do you use for a mill jig? Iím not looking to rip anything big.

    Something like this? https://m.northerntool.com/shop/tool...xoCCu4QAvD_BwE

    You should get the SCA trail work book.

    hmmmm, I don't see any mtn bikers doing that ^^ instead they buy wood and figure out how to get it out to where its needed, the local mtn bike association in some cases uses treated beams like for under a bridge which makes sense looking at it from the very long view instead of replacing an entire bridge 10-20 yars down the road ?

    My understanding is you need a pretty good pro quality saw the bigger the better, which is then heavier/ more expensive/ burns more fuel and then you got the jig which all presents more logistics problems if what you are doing is trying to mill the wood on site ?

    also every cut uses 1/4 " of your wood one of the reasons why bandsaw mills are better, I know people who have bought a bandsaw mill did the wood to build their houses and sell the mill to the next guy

    I did that. Welded myself an Alaska mill to plank out logs for wood features on trails.

    It works, but I concluded that my saw just isn't big / strong enough to efficiently rip logs. It just takes too long. Went back to buying / hauling planks.
