Fasciation, its when the meristematic cells divide wrongly, maybe as a result of excess plant hormones though in the past it often was from a whiff of 245t, a man made plant hormone mimic.

Yes it seems to have gone up by 40 quid delivered since I bought one in march 2015, good basic saw but a bit heavy by modern standards.

It was the family car from 1973 to 1984 when the youngest was 8 and it got too cramped, we used a LR88 station wagon bought at the same time for gymkhanas. Never had a breakdown but started using oil at 120k miles so I rebored it, only done 10k since

I was a bit hesitant about showing this as it's by no means concourse but it has sentimental value, We've had it 44 years but my wife can no longer drive it (MS) as it has no power assisted brakes or steering. It's good mechanically but rough inside and out. My mate Danny gave it a blow over earlier in the summer, mostly to protect it as the paintwork was failing. I have yet to flat it down and polish. The bag of pellets is stored in the back as a bit of ballast, I've burned the other three.

Yes that or some mite, they're too small and frequent for spider and the blisters would have been bigger.

I remember seeing melanistic?? grey squirrels near Boston 15 years ago, they turn black in hot weather, a similar thing has been reported in Norfolk within the last few years. So are these common greys, Sciurus carolinensis?

I'd say spider bite, the hard whitish bit in the middle being a small blister?

ANSI is a private not for profit organisation, who owns BSI? A quick Google shows it is also a not for profit company with a royal charter, no shareholders

You won't be responding to my thought that it is strange that a more entrepreneurial society like USA releases much its government assisted publications into the public domain (many will be viewing this using software developed from such a programme) yet UK makes its public bodies and first steps agencies charge for their output.

I started a similar thread and BMP01 told me how to start, this one was run with no oil, I don't believe old petroil mix would cause lack of lubrication though it could cause other problems, principally poor starting. It's uneconomic unless you do it yourself as the saw has little value. I only replaced the piston with a chinese one as meteor weren't available. NB the piston skirt slightly fouled the bobweights so needed relieving. I used Hylomar blue for the gasket sealant. It's long-winded and fiddly compared with changing the piston on a conventionally barrelled engine as, being a clamshell, everything from front handles to flywheel, ignition coil and clutch has to be removed before the two halves of the clamshell are separated and then the whole crank and piston reorientated to slide out of the casing. Good luck

It's the tension in the sling that is supporting the load and the doubled sling suspension assumes there is no friction so the tension is the same throughout the sling. Put a knot in it to prevent the load moving and then the tension is no longer uniform throughout the sling.

Not that I can think of if the valve is rated for the flow from the pump. If you want to try it with a standard valve you can put a rotary diverter between the piston port and rod port and tank such that in normal mode the rotary diverter blocks the flow from the piston port to the rod port and the rod port is connected to tank via the double acting slice. To increase speed on the forward stroke the diverter blocks the return to tank and opens the piston port to the rod port, it is then operating as a single acting ram. Of course then the ram cannot return until the diverter is changed and if system pressure is reached it can make the diverter more difficult to turn. If it is the pump and hoses that limit the system pressure (e.g. often rams and steel pipes are rated at 4000psi but pumps only 2500psi) the corollary is that a similar idea can be used to intensify the force by using a higher pressure as long as the working parts can stand the stress, albeit with a slower speed. So one could have 3 differing speeds and forces from one pump but nowadays it is often cheaper to have tandem pumps and switch one out to tank as pressure increases.

This looks like what was called a regeneration spool, when it is high speed mode the oil is delivered through the line which is connected to both ports on the ram, so oil being forced out of the piston rod side of the ram is delivered back in to the piston side. Because the pressure is the same both sides the force delivered to the log is the pressure times area of the piston minus the pressure times area of the piston minus the rod on the other side, so the force is much reduced in regeneration mode. When full force is required the valve slice moves back to a position where the oil just goes to the piston side and the rod side vents to tank. You can achieve the same result with a diverter tap in a line between each port. Regenerative valves are often pressure sensed so that as soon as system pressure reaches a limit (e.g. the splitter reaches a tough part of the log) is drops out of regenerative mode into normal for full force to be applied.

I'm no expert but when I've been bitten by what I think were spiders it has cause a small painful blister

PM cornishwoodburner on here, he hasn't contributed recently, he hires in big chippers to process his 3000 tonne per annum requirement so may be able to suggest tying in with his contractors. He's just NW of Plymouth

... and that is also why the offer wouldn't have made any difference as it only affects the claim for costs, and there cannot be any in a small claim. I had the same situation on a breach of contract claim I made, the other party paid half my claim into the court, I simply withdrew it and continued with my action, which they settled in chambers of the registrar when he said he was not going to hear the case and send it to the county court. You could have conceivably put in for un-liquidated damages of less than £5k but more than the cost of repair but in my view you had a good and just result preventing the guiltyr party getting away with it.

None now as I'm not working atm but was just pointing out that : 1) clefts can be more economical of resource than sawn planks 2) sycamore grown from coppice can produce clean straight grained wood, although often the pith will be slightly stained but this wood is discarded in the turning. Just a thought as bodging also traditionally used clefts of young beech

Looks like an ideal candidate for cleft billets. 5.5" squares to turn into 5" diameter allowing for shrinkage looks doable from 4 clefts out of a 14" diameter under bark log and we knocked over loads of clean sycamore coppice of that size and larger on railway jobs.

looked horribly like willow to me

I don't use my cellphone for reading arbtalk and never had the app but I’ve just tried it to view the site and I agree with Rich it' works well.

Just like we used to do but not having PA1 we'd just use ammonium sulphamate to help compost the stump

Many do sink when fresh, beech and oak do depending on time of year and part of tree but wood also contains gas spaces. Try it with a wood pellet, which has had the air spaces squeezed out of it and is only 10%mc wwb

I used to deal with this sort of thing with a small firm before I had to leave nearly a year ago so I may be a bit out of date: in the scenario you mention the material all comes under the EA definition of waste because it is the arising from the main contract (site clearance) which you would ordinarily discard. EA have a position statement on this and say that the "virgin timber", which includes whole tree woodchip" will not be subject to the normal waste rules, so it may be carried and traded just in the same way as if it had been produced from a forest. They do say that branch trimmings, such as hedge clipping and sweepings, remain outside this position statement and are treated as waste. It's only hazardous waste that requires consignment notes and this has recently been deregulated to some extent but covers things like asbestos contaminated waste, batteries, creosoted timber used engine oil etc. Other tree related waste that is not "virgin timber" will require a waste carrier's licence and transfer notes, it will also need to be "treated" to make it into a product that can be sold. This can be by a number of routes e.g. for compost it needs to get PA100 certification when it then ceases to be waste and can be sold on the open market, else it remains waste and will require a licence to dispose e.g by spreading to land. I am aware of a couple of arborists' yards which have applied for the relevant planning permissions, one which I was directly involved in still in process, and the formal requirements and reports necessary to get the application validated can involve expenses into 5 figures. The EA exemptions you linked to can be a can of worms but as you say many civils firms and Network Rail require proof of chain of custody. I personally don't think using the waste transfer notes as a proof of chain of custody necessarily negates the position statement about "virgin timber" if used to satisfy clients' audits (a bit like using white diesel in a tractor doesn't mean it's an admission you shouldn't be using red diesel). The main thing about going through the paper exercise of obtaining the relevant exemptions (mine were granted with no checks) is they are nullified if the site does not have the relevant planning permissions. IME very few arborists' yards have sufficient planning permissions for what goes on in them. Also bonfire sites on these yards are always unlawful if any plant material not produced on the site is used. You have to accept that once you take waste fencing, sleepers they should be taken directly to permitted premise for waste disposal rather than back to the yard. In practice everyone seems to turn a blind eye to skips kept at the yard for waste that comes back off jobs as long as the transfer notes and waste description are correct.
