Mr. Gypo i watch your scrawlings, your observations extend to mine in the tree, echoing sometimes hauntingly.
With the same gear we shear and set the same princi-pals to the same host. The comparisons that hold true in both can be the most defining in there consistancy, even though you walk your forces out to the far end, i can exercise them in more situations, perhaps more times in a day, for i can top diffrent leads of the same tree like small removals 40x+; i can turn the same set of rules sideways and try to keep track of all of the elements and test and further define them like that,as you further define them in the shear number spectrum.
But, i can not take credit for all of that, for in Dent's Book i found the quiet notion that he evacuated and dealt with tension and compression in hinging fibre in the exact diagramed way by the flow of the forces and recognzing them as in felling. For they are exactly the same but, just kinda diffrent!
i am just getting around to writing this, but it has been ringing in me to do so since you posted. In the diagram, i show another Duthcy that Dent defines, in this, that has been my dogeared bible that i always had to come back to; cuz i didn't get it the first few times, for sure!
As far as Dutchy's just being in felling, i find the same principles elsewhere too, equally set, so in that sense call them collectively the same. If to save lives the definition is just to restrict danger, okay to that higher order, but in terms of learning and definition, just as like the rose of any other name.
i myself, may venture to this SwingDutchy for felling, but not immensly, slamming it to capitalize on the push/lift of the stepped Kerf Face on the LeanSide of the hinge, more as a better triangle hinge pattern as holding wood on the controling, offside of the lean with soft help from the step lift. Certainly not the Swing Duthcman of lore that sweeps the spar across a slanted face suddenly.
In Dutchys for felling, i still think that save for a few with the feel; should be restricted otherwise due to the forces they invoke, and the immense scale and leverage of force they set it to being so far out of range, off the charts. i think that the main education is to recognize, how imperfections in cuts, faces, hinges, decay can invoke a Dutchman unrecognized looming. That includes how decay can affect the way a hinge pulls, or make one decayed face give out as the other side slams; and if that will help or hinder you possibly to task.
So, if the definition of Dutchmans is restricted to felling, what do we then call that which encompassess these same principles played out exactly the same way and the duthcmans collectively?
From Dent's book i have defined for myself the Dutchman mechanics as an interuption causing premature compressing in the face at some point(s) as the commonality of all of these things. Is that that far off?
