  1. Hamadryad, the CAD course I'm doing at the local college it is two hours a week for 34 weeks.

    There are two assessments as well as on going assessment of your basic computer skills. The cost down here was £220.

    The tech cert exams are split with written ones being done in the summer- not too bad if you know the syllabus.

    And the autumn management exercises covering id, development, tree condition and woodland management.

    The only external help I received for the whole course was the Tree Life prep course for the management exams, this is well worth the investment. The problem with the exercises is exam technique, the one section I failed was the one I was most confident about.

    Bundle 2 the replacement for the prof dip I am hoping will be easier for external candidates as it is going to be unitised, therefore being awarded when you have a certain amount of units, although I'm not sure if this is the case.

  2. Thanks for the replies, they are really helpful.

    I have passed all but one of the tech cert exams, and am confident of passing the last one on resit.

    Luckily I have no children so that is a bonus and have a HND in an unrelated science.

    Oh BTS I am doing C&G CAD at the moment, what luck.

    I think I could do it but was keen to get some idea on what course was like as I heard bad reports about the on line tech cert course.

    My other option is to wait and see what replaces the Prof Dip Arb.

  3. I was interviewing at an arboretum and cemetery to do preventive maintenance, and one of their new hire's was riding around on the grounds with us in the truck. I was talking about my experience, and their need to have someone out there on a regular basis, etc, to manage these old trees, etc.

     

    Well, the new hire kid gets the idea to go to some arborist school over there, swarthmore or somehing, to get "certified" to come back and try to be their "arborist" (with O experience) So...

     

    I am writing this in response to this thread, because its easy for a american average joe, to go over to your country, spend a year in this program, and think he's going to come back as a "certified arborist because he passes some classes, even practical tests, etc, and thinks he can come back here with credentials. This to me is not a good policy. I know here in the states, the ISA requires at least 4 years experience working with another firm, etc, and be studying a relevant topic, etc, before certification. This should be a little more regulated I think.

     

    ACUF

     

    ACUF I have sat the Tech Cert long after becoming an ISA Certified arborist,

    while your comment about experience is valid our tech cert exam is far superior to the ISA credential.

    Its not multi-guess for a start. I sat and passed the ISA cert arb with very little work, but have missed out by 4 percent on one part of the tech cert exam after more work and more gained experience.

    In other words you are not in a position to judge the achievements of the guys on here. The US do not have the best systems/ professionals/ sportsmen/ or anything for that matter, they are just insular and have an inflated opinion of themselves.:001_tt2:

  4. Member of the AA at the moment. I will rejoin the ISA next year as it is my re certification year.

    I have been disappointed with the benefits of being a member of both.

    AA come across as very professional, but they tend to let them selves down as they do not meet the standards that they require of others in their approved schemes.

    ISA have a great model but service is sporadic and the web site is not touched from one year to the next.

  5. I have also been climbing for 6 years, in tree work for 9, I dont claim to be the worlds best climber but I do love rigging, the more difficult ther job the more interesting it is, however, I also love simplicity and I think finding the simplest way to complete a job safely is the real challenge of dismantling.

    I did my first speedline job a few months back, I had gone 5 years without doing one because I had always found a simpler way, eventualy a job came along where a speedline was the simplest way.

    I think what you can see in this vid is the simplest way of getting the job done.

    and if you think there's too much slack you should have seen some of the stuff I did today, we were felling out tops of a multistemmed euc from 8 feet above the pulley... Why? because it was the simplest way of getting it down the pieces only weighed 50-100kg and there were plenty of leaves on them to slow their swing.

    I am sure that Mike understands the laws of physics and that if her was butt hitching 1ton lumps of oak hed use a bigger pulley and have less slack, but as he's a seasoned pro he's learned where rules can be bent and where they can't, just like a few others on here.:001_smile:

     

    Personally I would not be bending the rules in a video to show to prospective clients

  6. It was the only article I had time to read, I refer to the corrupted photographic evidence the HSE submitted to the courts, and the judge subsequently threw out. I take it by they you mean FJ, not the HSE?

     

    Andy, I don't know the case you are talking about.

    I am refering to the Rigging research, commissioned by HSE and completed by Liam at Treevolution in conjunction with Brudi & Partner TreeConsult.

    361 pages, available by download on the HSE website.

  7. I did no such thing!!!!:mad1:

     

    Sorry thought that your post:

    Jeazzzzzzzzzzzzzz!!!!!!!!!!!!!!!

     

    Its no wonder so few post vids!!!!!!!!!!!

     

    I think it was awesome, if I wanted advice on doing the job I would sooner ask a guy like Mike than the NPTC.

     

    was just that.

  8. Swing Cheek pulley's are almost always used in any kind of rigging now days.You can install them mid line and on the ones used in cable logging you can replace or tighten up the bearings easily.Actually with the exception of the tiny Petzel fixed Cheek micro pulleys I think you would be hard pressed to find a light weight fixed Cheek unit.

     

    The ammount of distance you have between where your peice is attached and where the pulley is does matter,but not alot it you keep it sensible.In my opinion having a longer distance with some room for error if the hitch should slip or you need to clear a bump is preferable to having it in a notch or notches close to the end of the log.

     

    Limbing when Spiking up is a great technique in the right situation.However trailing 150FT of line and dropping all the branches onto it takes alot of the speed out of it.If I am Spiking up I normally wear my Rope in a Back Pack already attached to my Harness with a Fig 8 and terminated with a Loop Sling.If I should get into trouble I can choke the sling to the Stem and come down.

     

    Yes,even one handed.

     

    At the end of the day its up to me and you to choose techniques that we feel comfortable with.I have only been doing this 14 years now.Like anyone in this industry there is still alot for us to learn.

     

    Mike I will apologise about the comment about the pulley as I can not see the exact model.

    The debate is not how you tied your section on but the slack in the pulley attachment

  9. If Blake is who I think he is, then he knows his stuff and i respect the points he is raising and the work he does for uktcc:thumbup1:

     

     

    And yes thats Qtip in the pic, i'm much better looking.

     

    No I'm not him.

  10. Six years, although it does not have any relevance on the laws of physics.

    What is everyones problem?

    There is a way to reduce the forces, why not do it?

    The forces are not huge it is a small piece, but the concept is correct.

    It would be more critical when you are getting closer to the SWL, so why blow smoke up each others arses for doing something that could be done better?

    Skyhuck chose to rubbish correct techniques at the start of these exchanges, why?

    That is why I pointed out training does not cover laws of physics, but uses the principles in the application of correct techniques.

    I do not know why skyhuck has such views on training, I have to assume, I may be wrong in my assumptions. I try to give balanced views and listen to other points of view, if I do not understand a concept I either will research it get training or not enter into discussion.

    Several members here can't debate, and resort to inane comments like "So and so has been doing it for years", It does not mean that it is right.

  11. It still doesn't matter, the increased energy is just dispersed over a longer distance so equaling the smaller force over a shorter distance :001_smile:

     

    Why have you stopped the smaller force over a shorter distance?

  12. I know nothing of your work, as you have not posted, pic's or vids.

     

    Is Mike a magician?? if you a are right how come it all went so well??:confused1:

     

    Skyhuck as I said with the forces and size sections we normally work with, it should go fine. BUT WHY INCREASE THE FORCES WHEN YOU CAN REDUCE THEM

  13. sorry mate, you're wrong

     

    No I,m not.

    If the section has accelerated, which it has if it is falling it now has converted its potential energy to kinetic being accelerated @9.8m/s/s

    This increased kinetic energy has to go somewhere which you are trying reduce by the friction device.

    The friction device turns some of the kinetic energy to heat energy( feel your portawrap next time)

    If the section is being slowed earlier by rope and not falling, the kinetic energy value will be smaller as it has been decelerating sooner so the forces are lower.
