Friction Hitches



What that we ever come up with is totally original?   



Jump to: Doc Shigo Profile Page- What much of trees would any of us know if not for the pioneering against the accepted knowledgebase of former Chief Scientist for the US Forestry Service; Dr. Alex Shigo, "The Father of Modern Arboriculture"!  That in fact did write the book...

Douglas Dent Profile Page-  Mr. Dent really lit the way for mechanical analysis of all of the forces and leverages on the hinge machine we use in his book; so aptly named: "Professional Timber Falling - a Procedural Approach".

TreeBuzz.Com Pro Climber's Site-  Forum Owners (Trainer Tom Dunlap & Many X's World Climbing Champ Mark Chisholm) offer a climber's, riggers etc. an open forum, including of course contest dates, results, info etc.

ArboristSite.Com All Tree and Chainsaw Folk Site-   All Tree and Chainsaw Folk Site for from climber to logger, pro to amateur,  Chainsaw builder, Chainsaw racer, user etc.

View Map  The Tree Service leader and  benefactor in specialty and ordinary tools, educational materials etc.

View Map Dave Spencer applied his clear thinking and correct  math openly, giving freely system design expertise on the discussion boards mentioned.

WesSpur  Serving Climbing, Safety Gear, other specialties to the tree and plant care industry.


The Price is Right; they say that if you think the price of education is high, try ignorance; well that is especially true, when your life is on the line, and someone will give ya the education FREE!  This is my best of free education of tree care, fascinating rope work, strategies etc.  i can't say which is better, no BS guides!
