  1. Hi, did the pti with similar experience, and passed it. I had the basic tree inspection course too and had done surveys and inspections a bit. As a climber you are doing inspections on every tree you climb, ie is it safe to climb or to rig off. Hope that helps. Jan.
  2. I have gone cheapo. All bags from aldi or lidl, have lasted 2yrs already and no issues.
  3. Rob, You provide lots of useful videos online for people to educate themselves i found them very helpful buying and setting up the mill. So I think you do a good job as a teacher already. If someone can't work it out from the vids then they probably need proper training. Have you thought of offering an Introduction to Milling course? Obviously you would be charging for this, participants could maybe get a discount on milling products subsequently purchased. A number of years ago I went on a one day chainsaw course for home users, we had to have PPE but no tickets required. There were about 15 people there so even at £40 a head it could be a profitable day. Just a few of my thoughts. Jan.
  4. I was over 40 when I started, 10yrs later and I cope with the work no problem. I run my own business now and have some younger guys working with me who are keen to climb and learn, so I don't climb every day. I wouldn't fancy working for someone else and having to climb 5+ days a week. Not sure i could physically manage that, being over 50. [emoji69]

  6. Hi Tom, I hope it's a busy edin/Borders office, not a ...'bust' one!
  7. RR668: Evaluation of current rigging and dismantling practices used in arboriculture WWW.HSE.GOV.UK This report presents the results of a comprehensive study into a number of topics related to riggingoperations used in the dismantling of trees in the UK. The information it contains should enable thearboricultural industry to determine good practice
  8. I cant remember the exact figure from my rigging ticket. There is some good research by the hse on rigging forces. They were dropping some big sections and I think it was 4 to 6 times the weight of piece. Its a few years since I read it so best check for yourself. The pulley doubling effect is why things like the safe block and x rings are popular, and natural crotch, as they add friction at the anchor point and don't double the loading. J.
  9. Sorry jules, you are totally wrong on this, very unusual for you to make a wildly inaccurate statement. I decided to do a we demo. Photo 1, drill on weighing scales. Approx 2kg. Photo 2, drill on pulley with rope, approx 4kg. To hold the drill steady, you have to apply a 2kg downward force on the other side to oppose the 2kg drill, total 4kg. RIGGING POINTS EXPERIENCE DOUBLE LOADING VIA PULLEY. J.
  10. Hi Pete, I was just expanding on your answer for the OP.
  11. Two times loading only applies to a static load. When pieces are freefalling (before the slack is taken up) the forces multiply significantly. Up to 12 times the weight of the piece, although up to about 6 times is more the norm. With a good groundie letting stuff run and slowly decelerate that greatly lessens shock loading the system. If you have a 100kg piece, rigged from below, with 1 to 2m slack, stopped dead you could create a force equivalent to 600kg on each side of the pulley, meaning 1200kg at the rigging point.[emoji15] Something to think about. J.
  12. I got given a pair of old North face gore tex salopettes, they were great at keeping me dry. They were a bit nippit when I got them and after a few years were too tight, so i passed them to my groundie. I now have some bergaus ones that were over £100 new, and they work fine too. J.

  14. Coombe Abbey is a great place. I grew up near there, I saw beechwood yard when I drove past with the family last time I was down visiting family. There were always some big fish in the moats there.
