Thanks for the clarification... makes sense that the pressure in compressed wood, will cause the cells to be denser. Denser seems like it would be stronger to fight compression, but not necessarily tension. Don't know about the speed of sound thing.. but I do like watching falls in super slow...

heard somewhere that all good hinging trees were strong in tension.. going to bed...

It was just a theory Jay.. one that makes sense, but may prove to be wrong.. your explanation sounds a bit simplistic.though. I thought there were different types of wood strength.., strong in tension vs strong in compression. also thought that conifers tended to put on more growth in...

Perhaps one important consideration would be to include "when falling with wedges". I think that is the crucial difference here Stig, especially on side leaners, where the fibers on the tension side do the most to fight the lean. Makes sense eh? That's a much different scenario than pulling with...

Any comments from you (Stig) or Tucker on the above pic? Those center fibers aren't toothpicks.. huge holding power.... I don't remember the tree Jed.. Looks like a Norway maple..not sure why I nipped that corner, but it seemed like a good idea at the time...

Not sure what you guys are talking about... the monster fibers in the center of this hinge tell a clear tale.. extreme holding power of both fat hinge and center fibers.. (just happen to run across the pic today).. ps al.. bpz is branch protection zone (don't mess with mother nature)

Mostly they get hollow from improper pruning cuts.. very prone to unstoppable decay once the BPZ has been violated...

I don't recall ever having used a step cut with a "thicker than necessary" hinge.. the two have different uses and do not combine well... if you took the time to watch a few videos, you might get a different impression.. I use what is needed in any given situation... with a few extra tricks in...

Me too Al. I use thin hinges on backleaners, 1" or so on many, and gut if needed... thick hinges are for side leaners.. check out 5:15 of this vid.. silver maple, notoriously waek hinging.. side leaning stick over a little apple... You can see and hear, especially ion slow motion, how well the...

We have a difference of opinion on this one.. I have no idea why you would say that. I have found over many trials on some tricky falls, the exact opposite to be true. You and Stig obviously have a lot of experience..... Have you done a lot of pulling with the skidder winch? There has to be some...

cool ... you sound solid... so you on't watch vids? if you did .. wonder would you laugh or cry?

When you're pounding wedges, "fatter than necessary" means beating away 'til yo9u're out of breath, with nothing to show for it.. Different jobs, different tools, different perspectives = differences of opinion... as a logger it makes sense that a fat hinge is nothing but a ball buster at...

ya... the gut and the yellow hard hat are sure give a ways. Been on that cut since 1989 Al...

We have a different point of view... I have plenty of experience and experimentation to back mine up... maybe its a difference in species... I mostly go with thick hinges in the poor hinging species.. never really needed them on anything else... they hold remarkably well if you have enough power...

They may be important in preserving a logs value, even crucial... And that's not what he said... "bear in mind that a thinner, more flexible hinge may well hold better in this scenario, than an unflexable beefy one!" maybe thinner is "preferable" in some scenarios... less resistance on a back...

I keep trying, but it doesn't do any good.. you;re still spouting the same nonsense about heartwood and thin hinges...

Here's a comment I just got on a youtube vid of pulling a backleaner.. no step, just a couple of wedges to keep the bar from pinching on the release, just as Stig suggests.. "Seriously, what the frig good do you think it was putting those wedges in?! Then standing in the pie that the wedges...
