Yes it leaves an air space, wood without the airspace has a density of about 1.5 times that of water. PEG poly ethylene glycol is used to displace water and wood treated with that is heavy.

also at the bottom of the page next to another "view unread posts" is "mark site read" which means you only see new stuff next time you log in

On a desktop PC using firefox I see "view unread posts" in the top right corner, this seems to list all recent posts in a reverse chronological order (newest at top) On those posts next to the username is a small black dot or star (what difference I don't know) this takes you to the last unread post

I don't know how the link ended at the top of my last post but what I should say is the link came from our local RFS secretary and he identified Diplodia as the problem with scots pine in Surrey.

https://www.forestry.gov.uk/pdf/fcin068.pdf/$FILE/fcin068.pdf I've seen the pictures now, the blueness of the foliage suggests scots piune? It would be easier if you posted them as jJPEGS rather than PDF. It doesn't look like red band needle blight. Is the dieback only on the current years growth? Have a look at:

It's a while since I did one and that was a 490 but you need to remove the clutch cover from the engine, it looks like you have the machine screws out already, it should pull off. Then as you say you need to release that circlip, it's difficult but doable with a long screwdriver

Well done: elements of the original and the derail. Cscope also do Cable Avoidance tools which work on an entirely different technique from the detectors. Detectors depend on the metallic object changing the capacitance or inductance of a circuit in the detector whereas the CAT attempts to pick up a signal being given off by the metallic object. Hence if you can induce a signal in the metallic object you should get better results, normally only possible if you have access to one end of the wire but as I said earlier it may be possible to induce an eddy current in a ferrous object which would give of a signal.. With the CAT there are two receivers used in induced signal mode and the difference in time between the signals being received is used to calculate the depth.

I have an infestation on my apple tree which I would like some advice on. It is the main feature of a small garden and I haven't done any pruning in 35 years. This year it had a bad attack of blossom wilt also. I think the infestation has got worse over the years such that 50% of the fruit has fallen already. So, as there are no other apples in the immediate vicinity, is it worth removing all the fruit for a couple of years in order to reduce the population of overwintering as pupa? Or similarly maybe pruning back the fruiting spurs so no fruit for a year and maybe controlling the wilt also?

I cannot see the pictures atm but likely candidates with be: Fusarium circinatum pine wood nematode Dothistroma Needle Blight Depending where you are and which species, Scots pine is affected by the latter less than corsican or lodge. Another new to me but lesser evil was mentioned ata recent RFS meeting in Surrey but I didn't note the name

For completeness rather than feeding under bridge dwellers: "To make a Damascus gun barrel, ... The steel was often something like well used horseshoe nails, nails, work hardened by being hammered against the road many ..." The originating site is down but the precis is still found b a search engine

Mea culpa, anyway I was told that one needs the wood to pass through a coil to get the best detection. I would have thought with high power MOSFETs you could induce a fair current in a piece of ferrous metal to increase the signal, non ferrous being less of a problem if small.

You want jam on it too?

Seems okay in firefox under mint17

"In 1806 J.Jones was granted a British patent for the production of gun barrels using iron from horse shoe nails and steel from coach springs. The Damascus barrels were made by layering anything from 8 to 24 pieces of alternating strips of iron and steel and forging them together. These strips were then twisted into a spiral and used to make a 3 or 4 piece plait. The whole piece was then beaten flat into a ‘ribbon’ that would be twisted around a central mandrel (solid rod). Clockwise for the right hand barrel and anti-clockwise for the left. This ribbon was then hammer-welded together (forged) and the central mandrel removed to leave the barrel ready for boring and striking off." Now not every patent gets used but...

Apparently shoe nails were used to forge blades from as it was thought the constant pounding of the hoof gained them something, which was actually lost when they were reheated. Are limes associated with farriers or blacksmiths? We had 5 outside our local farriers before it was redeveloped and the one nearest the door was riddled with iron, I managed to fell it but gave up crosscutting it and half burien it elsewhere for a stag beetle to find.

I used to drive a 6tonne Smith's electric out of Merton and up the A3 to Tooting in my holidays when I was 17, it had a good payload but frightening joining the dual carriageway at 12mph even back then. I don't thing there was a weight limit on a L category then. That was in the days there was a separate category for a trolleybus and that didn't come with the car test. BTW my mate in Hemel has a milk float for sale, he used to drive it to the shops.

Swarfega orange now has cornmeal as the beads and seems to work just as well as the Goodstuff orange

Viburnam opulus guelder rose??

AFAICS and I have never owned or used a fast tractor: ag, forestry and horticulture are allowed for both tractor and rebated fuel but as soon as a load is carried or hauled the radius restriction is 15 mile after which operator's licence is required. Thereby hangs a tale about shipping chipped forestry tops to a power station using fastracs the perpetrator was fined but claimed he was better off as it forced him to use lorries and his overall costs went down. Except that running on rebated fuel is allowed for domestic tree surgery, but not hard landscaping. You are free to used DERV and HM Revenue & Customs may be happy with that and turn a blind eye about licence and op licence infringements, or probably don't realise the requirements. The problems arise when working on trees in commercial or industrial sites, then they take the view you cannot use rebated fuel as it is not ag hort or forestry related, then of course if your outfit exceeds 7.5 tonnes you are in the situation of evasion of road fund duty, require a HGV licence and tacho, operator's licence and driver cpc. There is also the anomalous situation whereby you could drive to mow a school playing field using rebated fuel on a self propelled mower but not in an agricultural machine with mower. It is also confusing that HM Revenue say it is only interested when the machine is used on roads maintained at public expense which is very different from land covered by the road traffic act, I'm still not quite sure of the position if I took my county and trailer (over 8.25 tonne so more than my C1+E allows) to a local show, I know I should use DERV after flushing the tank but what about the rest? Having said all that I was only ever stopped for not displaying a number plate and I know several firms that transport diggers behind agricultural tractors, my old firm shifted yards using the JD and low loader with no problem.

I only know him from posts here but please send him my best wishes for a good recovery.

It has been resolved it's just that it's arcane and there's not much logic to it.

Pardon?

Brilliant, did it float?
