I think a lot of the trees we see in woodlands and edge lines are self seeded and have a lot of genetic diversity whereas a lot of planted ash were grown from selected seed for better timber, often from abroad, and thus had less diversity and were particularly vulnerable. Jo Clark at future trees is growing stocks from trees that have shown better resistance, they graft the collected scion onto another rootstock to enable an earlier seed crop. She says no ash are totally resistant so as the spore load goes down those with better resistance can cope. On our site we had ash, growing over a clump of yew, that appeared less affected and she put it down to the spores from leaves that had fallen not having been able to get through the yew to infect the new ash foliage.

Could anyone familiar with these old Stihl saws have a look at this picture to see what they think may be wrong, the brake is held on because the distance shown by the red arrows is not far enough to cause the knuckle circled in blue to go over centre and hold the band off the clutch drum. I cannot decide whether the front handle may be bent, the brake actuator handle wrong for the saw or the part circled in blue worn or defective. I'm not very familiar with Stihls but have had 4 dropped off after they were retrieved from the workshop of a dealer who ceased trading. Not much else wrong with this one apart from a cracked rear handle, broken coarse thread screw stuck in the top AV and fuel filter clogged and carburetor full of fine dust.

If they were on his property the conveyance should have flagged it up. Until the council prosecute there is no loss. If they do prosecute and win then there may be a case against the conveyancer but I don't think you can get compensation for the cost of a fine in a criminal offence. He had the tree felled and ignorance is no defence so it will be interesting if the council do get involved.

The regen function connects both ports of a double acting ram to the supply, so the force extending the ram is the hydraulic pressure acting on just the area of the piston rod cross section. The forces on either side of the rest of the piston being equal and opposite. Some log splitters use it to quickly take up the slack before the ram contacts the wood and start the split, once the supply pressure exceeds a limit the rod side of the cylinder is dumped to tank, so the pressure is exerted on the full area of the piston. Gas struts work in this "regen " configuration.

Thanks, have you a part number for a 3/8 drive sprocket or rim for the 2100. I'm guessing an 89 drive link 3/8 chain.

Imagine you want to strip the bark off a tree cleanly, when would you do it? this is when you would avoid laying it as you need the bark-phloem-wood interface to remain intact.

Check out the RHS site. I had no success with mine but @Peasgood is the orchard man.

I've dug out an ancient unused 26" Husqvarna bar 501 60 31 01 BAR 26'' 3/8'' I want to know what the mount is in case it would fit my 2100CD , I would have to change the clutch sprocked from .404 to 3/8 else would it fit my Jonsered 920? The 920 is missing its dogs and I need to verify the part number is jonsered 5382419-92 if any one knows? @adw I have swapped bars off the 929 and they seem to be the same mount

My take on it: I think growth is in full swing and a bit earlier than usual and would now wait till September but I aam no hedgelayer.

You need a clean cleft and the proportions of the flexible and elastic sapwood on the outside of the bow with the strong in compression heartwood on the inner. Yew woods grown with competition between the trees to yield a clean stem were the preserves of royalty, I did work in one, owned by a knight but not royalty, who established it just after the war. I was clearing up after some unscrupulous fellers had ripped off a load of veneer butts in an older part of the wood.

Difficult to say without more context, was the initial bark damage from abrasion by a tree stake. The damage is a few years old and subsequent damage likely from insects living on necrotic tissue. the size of the gallery and exit hole suggests a larvae has bored its way out, maybe a goat moth.

No need really, we have mains water and the sewerage rate is linked to our usage ( not intending to go down the composting toilet route) so I have to pay the standing charge and our daily average is 70ltr so no real cost savings are possible. I flush the loos mostly with greywater.

Sounds good. My well is only 12ft deep and filling a couple of water butts will empty it but it generally refills in a day. I normally rely on rainwater as it's a faff lifting the cap and dropping the submersible pump in. From what I can gather it never was a traditional well but a hand pump shared between the two cottages. It looks like it was used to dump old bits of pipe in before it was capped and the mains was connected. If I were younger I would dredge it and should have done when I was.

I don't know about diggers, I haven't owned one for 35 years, but while I agree in principle most of the Chinese made stuff I buy is only available from there. Our business owners sold out and gave them a real monopoly.

I cannot remember having a handle for mine. It did turnover for a while before it started.

Yes Morris minor could be had new in 1970, dunno about 2CV never played with one. My 1973 LRs definitely had starting handles, not sure when that stopped, my 1990 110 didn't have one. I think my 1967 imp had the shaped hole in the bumper but just a bolt on the crankshaft rather than the spragged orifice .

As @rapalaman says I was flagging the query up for you as the original poster is potential competition for you 😀 -
I remember starting a Renault in the snow after a girl had left the lights on for a party with the starting handle it would have been 1969 when the only other cars with starting handles tended to be automatics.

One of the things w saw with scots pine stobs and posts is that the sapwood absorbed water borne preservative well but the heartwood did not, such that over many years the middle of the posts rotted out but the outer layers (which actually got an overdose of preservative because of the way the chemical was measured in and out of the treatment cylinder) did not rot.

No it wasn't on rail, Spring 2010 NR suddenly pulled all the funding and there was a few weeks scrabbling around until the started awarding work again.

Yes but the difference is gnat's piss in the scheme of things. I think a 4 stroke small liquid cooled engine running a DC charger at constant optimum power into a battery would be more efficient than running a flywheel and its fan at constant speed but it would need a rethink of how it chipped and probably load. I expect all the chipper firms will be investigating, hey @PeteB? I see, advertised here, that Timberwolf have a hybrid with a small engine (beneath the size needing pollution controls??) that stores power produced at high idle, between chipping, into super capacitors which then feed an electric motor to increase power on demand. What they don't mention is the energy capacity of the system and how long the assistance is available before recharging.
