never start with the angle cut, ever, regardless of which flavor cut you prefer, only exception would be a birds mouth.I can't believe some said that Humboldt is easier. Im a beginner and I was teached with conventional starting by angle and finishing by flat. I have tried several times cutting an Humboldt and I always endup not matching the cuts together whereas making conventional works perfectly the first time. I must do something wrong when i cut the Humboldt. Do you guys have any tricks for helping me ?
Its a lot easier to line up your angle/slope cut to a level cut (gun cut) and its a helluva lot more accurate to keep the saw level when "gunning" the cut hence "gun cut"
once you've established your gun cut, its just a a matter of eyeballing what angle you want your slope cut to be, then you cut only until the slope/angle cut is INLINE with the gun cut, if you fall short you can recut it, if you find your self too low on a humboldt, just stop and chunk out the face, if you are to high (a dutchman) then cut a little more out until you have the cut opened up. WHATEVER YOU DO DON'T CHASE YOUR GUN CUT, stop and look make sure you never go past the line of your gun cut on either side of the tree.
This little detail is what makes the Humboldt easy, its forgiving, you can be low, and as long as you stop and clean out the face, it will still go where you want
Starting with a slope cut your are adding multiple angles to deal with and account for in aiming the fall of the tree, any time you add more variables you add more room for errors, start with the flat level cut aim carefully, take your time on it, then base all your other cuts off that cut, once its established, its ultimately the one cut the effects the trees fall more then any other.
Another trick with Humboldts, is to set your felling dogs (they aint meant for bucking FYI) just a little low of the gun cut, point the bar at where you intend the tree to go, lower the tip until you get the desired slope angle, then use the dogs to rotate the saw through the cut, 90% of the time with a small amount of practice you'll be dead on
