I guess I'm about 3/4 of the way to having replaced all my old kit that I got rid of 7-8+ years ago... A few more little bits to get, and a few more to try before I buy (hopefully Wednesday I'll get to F R Jones to play) and I'll be ready. Then its on to the one thing I really should have done 20 odd years back... getting some certs'.

Think this is as large as they go now... Makita UK - 5143R - 355MM CIRCULAR SAW

Danwill... got any pics?
-
try one of these... Simple, very light, but only good for about 10 minutes a burn. Really sorry about the annoying tune... [ame=http://www.youtube.com/watch?v=fbHHQrh9m58]Capillary Hoop Stove - universal - - YouTube[/ame]

Think it'll be fine as a heater/cooker... will weigh an absolute ton though. made out of steel girders. Great for a shed or similar though.

Special!!!

30.04 Tony... one of the hardest to catch in the land mate. (no joking either) I'll stick a couple of other pics up of it if you like bud?
-
Not what I thought you meant there then... lol Same end result, I just wasted more time getting to 4 ton...
-
Its the thought that adding the first pulley up the tree actually doubles the force that messes my head. Tie the weight straight to the tree and it is just the mass ie 1ton in this case, that is taken by the tree...
-
is that the sort of thing you mean Pete???
-
Oh, it used to be easy... I used to be up a tree like a squirrel. Then I attained a paunch, got out of practice, and found the TV remote... not good:lol:
-
SRT, just looking to make things as easy as poss... so I can sleep through it if possible...
-
Looking at another pulley involved... A and D are now 0.5 each, whilst B and C are now 1 ton each... (I think:lol:)
-
Point A is 1 ton, simply put, the effort to hold the weight is equal to its weight. If point A was up the tree, and where the weight is, was the branch and the lowering item was on point B, then with point B being one ton, the other two point (if all was equal) would be 0.5 ton each.

had to get up a tree today for a mate and decided that it was way too much like hard work doing as I always have (pulling myself up whilst walking the trunk (if that makes sense)) so once I was back on terra firma, decided it was time to get some mechanical help. Thinking about left hand with foot strap, and right foot combo by petzl. Is this system any good? or should I look at other makes or set ups??? Cheers in advance, Martin
-
Cheers Dan... And thanks for the chat last night.

Safety glasses are far better than just the visor... Always used to get chips flying around inside the visor, so started wearing goggles as well. Don't mess with your eyes, they damage far too easily.
-
Thanks Pete... Always thought that was the case, but then got questioned about it today and really couldn't work it out...
-
Below is a very simplified diagram. I have been looking through lots of pages to find out the forces involved at differing points on this pic, but nowhere I have looked explains the force at B. By my reckoning, A should be working as would a fixed point in a 2-1 pulley system, the weight should be working as the pull/effort in the set up, which would make B the effective weight of the pull/effort x 2??? Is that correct? Please note that although the pulley at B is fixed to the tree, it is the force on the tree that I want. thanks in advance.

Or you're constantly doing stuff for free... I have a mate that usually helps out as a groundie, but sometimes I'm relying on an ancient bailiff, so I'm up there with a bow or silky, trimming what needs trimming.
-
One of the things we do on one of the angling forums I visit, is shuttle peoples purchases along between us... May be worth a bash?
-
Would this work as well? Meaning no staps/slings???
-
Yeah, the great idea of having half a door closed, and the top section that sucks out and creates an inch gap at anything over 20 mph...
-
Where from? where too?
-
You sure that's not you're groundie?
