The high speed tracking we had worked on the standard flow but halved the number of pistons in use in the final drive, thus halving the torque but potentially doubling the speed. I imagine modern diggers use much more sophisticated variable displacement pumps. You could put a priority flow valve in the circuit but these work on black magic and can overheat the oil unless they are positive displacement ones (which I have never seen used)

I'm well out of commercial work now but could pop in to look, I was a woodman for over 35 years buying standing and selling to mills but retired from that for last 20 years. Where are you? I'm in NW Surrey
-
This was my first thought too, even though I was not aware you couldn't track and cut. It probably only draws a few hp and a 5hp power pack for my jussi only cost 500 quid IIRC.

Meetings with remarkable trees, the Arbtalk version
openspaceman replied to Steve Bullman's topic in Picture Forum
Expected but so sad, a good bloke and knowledgeable too from conversations on and off forum. -
I've not bought any new big equipment other than cars but can affirm if you are unlucky enough to require warranty work it tends to be begrudging and shite. Being non specialised in which tree work I did I tended to need a variety of equipment that could sit idle for months, finance on new stuff did not fit well with this.

Alright for you Gunga Din, not something I would risk with a shredder blade in rough areas as it can fling bits of metal with a fair force, mind I am happy to use it with the standard Stihl guard with the black rubber strip removed.

Thanks I'll have a read tomorrow

local wildlife (fur,feathers and beasties)
openspaceman replied to Adam Bourne's topic in Picture Forum
I was thinking colarado beetle and mentioning potatoes seems to confirm it. Still notifiable in the UK IIRC -
The salient point being in hardwoods the extra cellulose give strength in tension (the top of the branch) and in softwoods the extra lignin gives strength in compression (the bottom of the branch).

I expect you argue conscientiously. I used to enjoy odd days in the yard running the log processor etc. nowadays I'm bushed by 13:00

Finding a home for arisings from habitat maintenance is a problem the wildlife trusts just don't seem to want to address, on heathland sites they bale, scrape and dump stuff in the treeline and that's no long term solution. Burning (swaling) would have been the way to promote new shoots in the past. For over 20 years now I have advocated making use of it for heat and co production of biochar but get no interest.

I've been debating trying this on a stihk where the flywheel key has sheared but not felt courageous enough yet. I'm guessing one must mark TDC and whatever advance it needs, assemble it and then use a strobe to check how close you get.
-
Quite but in an earlier post he said just up the M40 in Bucks. I'd guess for someone who knows a bit about what they are doing who's at a loose end about £120/day for 8 hrs including travel.

No, tell us about it. Where are you?

What comms/Bluetooth helmet or ear defenders
openspaceman replied to essexjack's topic in General chat
Any chance of a photo of the helmet mount? -
I don't know how it will affect carving, you'd need a wood scientist for that but look at the way the heartwood does not coincide with the annual rings. Generally reaction wood is denser than normal as the growth is affected by the extra strain, so the tree expends a bit more energy laying down wood to counter the stress. Oak sapwood is very perishable.
-
Looks like sessile oak and 2" of sapwood at the narrow bit would not be at all unusual. The thicker sapwood is reaction wood because it is a branch
-
Yes I would expect a slip clutch to be at either end rather than the middle
-
Yes she was a hornet but I have seldom seen one close up and not flying. She had a damaged wing and I'm not sure if she managed to fly off.
-
Thanks Paul, I thought the brown band on the abdomen by the thorax was a bit too wide for a common hornet. Here's a better picture to confirm before I let her go.
-
Can anyone identify this feasting on a rotten pear. I'm a bit worried it is not a common hornet.

Sweet Chestnut and Walnut
openspaceman replied to trigger_andy's topic in Forestry and Woodland management
None left here but they were plentiful in my mother's childhood. I've only seen them in the lake district. Anyway they prefer pine woodlands and I don't think their tastes are quite as catholic as greys. Greys outcompete dormice here because dormice wait until the hazel are ripe. Sad anyone would run reds over. When you plant I'd advise planting a few small trees rather than standards and thin them out as required. -
Sweet Chestnut and Walnut
openspaceman replied to trigger_andy's topic in Forestry and Woodland management
cobs are just hazels with ten times the nuts, very nice roasted that's what is in cadburys wholenut. Presumably you have the advantage of no grey squirrels. Down here they destroy them before they are ripe. -
Sweet Chestnut and Walnut
openspaceman replied to trigger_andy's topic in Forestry and Woodland management
Even as south as I am chestnuts are much smaller and slightly bitter tasting compared with ones you can buy from Italy but that may be because the varieties grown were mainly for producing coppice poles. Have you ever managed to pick walnuts, chestnuts, cobs or cherries that were edible locally? There is a reason that oats are grown rather than wheat as you go north. Also vegetative storage rather than seed crops, e.g. neeps or tatties. I'm not saying it cannot be done as I've never spent an autumn that far north. -
I don't know about the 165rx as I only had the one 165r and then moved on to little Husky 240s, I still have one. I then went for Stihl FS380 which is the one I mainly use with a shredder blade.
