What aspect of your insurance do you think would be effected by you climbing on SRT. I assume you mean public liability insurance, so how would your liability to a third party be effected by SRT?

One hour should always be a lot more than an eighth of your day rate if that makes sense. Its called economies of scale or something. Thats why a large jar of marmite cost less than 4 quarter size jars. So what I do is charge double for the first hour and the last hour is free. So if I do four one hour jobs in a day I get paid double for each, but if someone want me 7hrs or 8hrs then its the same full day rate, I cant make up that extra hour. This means I would get paid more for two half day jobs than I would for a full day, and that is how it should be. The client is not gettting great value per hour but then they only want a tiny stupid job doing and that has to be more exensive. Large multiple day jobs are far better value to the customer but then its only one quote/visit so much easier for me aswell.

Its just that to get things to actually hang vertically you usuall have to go much further out than you think and into much weaker wood, or cut off more at the fat end to give extra weight which again means you deffo need a strong attachment.

Adam, I dont think tip tieing should be done by actually tieing onto the tips of a branch. Your tieing on to a potentially heavy branch at its weakest point. Half hitches at the end are ok to keep it aligned, but the rope (or slings) should continue along the branch until you get to a strong enough point. Much easier to achieve with slings than rope.
-
Thats ok, you dont have to reference my thread but it might be useful. Its probably my best so far in terms of taking time to explain things.
-
Do you pay rent or a mortgage?

maintaining the rope as weakest link help?
Rupe replied to wrekin tree care's topic in Rigging and roping
Ideally a 16mm rope should be used with nothing smaller than an ISC medium cast pulley. -
Also, remember that the redicrect is not just a redirect, its taking some of the load and so should not be too much smaller. Also it changes the direction of force on the main top pulley from a downward force to a sideways one. Its is very often a good idea to put an identical redirect on the opposite side of the tree just to even this out a bit.

Isn't Bergen the wettest place in Europe?

Most old t shirts will do that.

Well said!! Its a fricken T shirt, what do you want it to be good at?

Even in those days there was some H&S. The sad thing about fred is that he was old school and cheaper than the "pros" of the day who would have used explosives. We love watching him work, but then we moan about people getting cheap treeworkers in to do our jobs. Fred was not much different, proffessional firms were around in those days but he was just cheap! And the police etc who were there at the time wouldnt have known any different so it went ahead.

Yep, if the line remains taught the whole time, then it doesnt matter where its tied off. But the maths of it is quite simple, you use the distance to the COG to calculate how far the thing is falling, not the distance to where its tied. Of course the top end of your log falls a long way, and the bottom end falls not so far, but the COG takes all that into account, and its still irrelavant where its tied on. The reason you dont tie beyond the COG is cos you dont want the piece to flip over, and tieing lower (nearer to the gob) will help the piece to lie vertically when its being lowered, so still could be a good idea, but has nothing to do with the distance of the fall.

That dibnah one is still the best! I wonder if the modern demo crews go home and watch dibnah videos on blastalk.com

The list is endless mate. Specialised is one of the few that still has its original founder still on the board, the rest are just brand names that get sold back and forth and many companies make bikes under lots different brand names. Trek and giant make lots of other bikes. There are some independent companies still going but the bikes are expensive. "independent fabrication" is probably the best and is run by the original frame builders of "fat city cycles" which went busy years ago.

Peter, how many clicks per rotation on a Hobbs?
-
I don't think you would get anything with a fixed bollard, the friction is there to slow down a large lump so unlikely you could pull against that friction fast enough if at all.
-
Yes it's VERY smooth now. We rarely ever take the fixed bollard, I would only use it with the 19mm for proper big stuff. The winch unit will handle everything and you have it there for the times when you didn't know you were going to need it.
-
Anything like this one?
-
How is that an advantage? I see them as both the same in that aspect.
-
Kind of been answered already, but, you dont need to crank it at all, your not trying to lift or move anything against gravity. Cranking can only be done when you have the full amount of wraps in place and then you wouldnt be able to lower it, so potentially dangerous when topping out, or negative blocking ("snatching", isnt really the correct term if using a decent bollard) So, you just put on the number of wraps that you need for the piece being cut and pull tight (by hand) before the back cut goes in, the GRCS rotates as you pull tight so its very easy, then as the peice goes over you pull in any extra slack, and then release. Usually only ever amounts to a foot or so, or one pull in of your hands from full stretch to the body, if that makes sense.

My first mountain bike was the exact same model as the yellow one in the picture and that was stolen within a few months from school. Then I had a further 3-4 stolen throughout the 90's. One benefit of these olds bikes now though is they are less likely to be stolen, its all the 3k full suss bikes that are getting stolen to order. The thieves put together lists of what bikes live where by following people home from mountain bike centres, then they find a buyer for any one of the bikes on the list and then steal it, drop it straight off with it new owner so they only have possession of it for a short space of time.
-
Thats not actually true, its the distance the centre of gravity ( COG) of the piece you are cutting is away from the block that that defines the amount of travel. As long as you tie on between the gob and the COG then its irrelavant where you tie, as long as its not beyond the COG. In fact, if you tie on as high as possible (still below the COG) then the groundie can pull in more slack as the piece goes over and that will reduce the amount of travel. GRCS works well for this.

I did have this orange bike for about a week. Its a '90 prestige, so not that great but ok for some parts that I needed.

Saracens were only halfords jobbies after halfords bought the brand, got them made in malaysia and it all went down hill from there. Before that, saracens were handbuilt in derbyshire, unfortunatly "halfords" has ruined the image of the brand, but the same can be said of cannondales, they are now just mass produced junk. The yellow one is an '88 saracen tufftrax, so very similar to the muddyfox courier.
