ToolsPosted by Dennis Hopkins Sat, January 06, 2018 02:50PM
An old brushcutter engine had carbon deposits in the top of the cylinder and piston, and in the exhaust port. It was decided to try to remove this because any dislodged pieces might damage the engine. For this I used some carburettor cleaner which slightly softened the carbon, a perspex scraper and fibreglass tip "pen". Of course it's essential not to damage the cylinder or piston, so using any tools harder than the cylinder/piston metal isn't recommended. The perspex is quite hard, part of an off-cut, and can be cut to shape with a hacksaw. The fibreglass "pen" is usually used to clean circuit boards etc., but worked well as a second stage tool here (the fibres are a health hazard to skin, eyes).
After a couple of hours most of the carbon was removed, except for some very hard material at the top of the cylinder, some of which was embedded in pit-damaged areas which will have to stay as it is. Some 1200 grade emery paper was used to lightly polish the piston (after photo was taken).
Of course this is also a good time to check the condition of the crankshaft, bearings, and wear on the cylinder, piston and rings, also that the ring(s) can move freely in their groove(s).
The engine seemed to run more smoothly after doing this, but it could be my imagination ... at least it ran.

I prefer to write "wintery" but that's out of fashion it seems.
It's mid-December and roses are still trying to flower, adding some welcome colour in the garden. Time now especially to feed wild birds, and it seems a squirrel, seen in a local garden ...
Trying to discourage all but small birds, this cage within a cage works quite well (outer part is a cylindrical piece of wire mesh).

It was around 15C today (9 March 2017), which brought out quite a few large bumble bees onto my winter flowering heather. I haven't identified the species yet - most were as shown in photos and the video
. I've put this post into the "Wildlife" category, but the situation was my garden, and the food plant is not native to UK. I wonder how the bees are managing in our disappearing and fragmented countryside ... Click for Video

I was impressed to see over 30 new buds springing from the stump of a young hawthorn tree I had severely pruned (planted in wrong place, oops). This was about 2.5 months after cutting. I believe these are termed adventitious buds, which are dormant buds springing into action if the tree is wounded, for example by incompetent gardeners, or more planned activities like coppicing and hedge laying.Feb 2017 +2.5 months after pruning
I'm hoping to keep the tree small in case the roots damage a nearby wall, and I intend to add photos to update the tree's progress in surviving my pruning.One of many information sourses on wwwApril 2017 +5 months after pruning (shoots ~ 20cm long)July 2017 +8 months after pruning (shoots ~ 30-40cm long)

I was impressed with this blue fungus growing on an oak post, initially thought it might be a lichen. A Gwent Wildlife Trust person suggested it could be Cobalt Crust fungus (Terana caerulea), later confirmed by the Gwent Fungus Group who recorded the apparently rare find.

Shopping - FinancePosted by Dennis Hopkins Sat, December 10, 2016 05:40PM... and not only the "bargains", things with price labels different to that charged at the till.
I've noticed in recent years that down-marked price labels in particular don't always match those charged at the till in some grocery stores (parts of large chains, for example SPAR
). These are sometimes known as "convenience" stores, to whose benefit I wonder sometimes. In a recent example, a printed discount label for an item showed a shelf price of £2.00, but I was charged the original price of £2.50 (shown on the receipt). When I queried this, saying a similar thing had happened many times before in that store, I was told that it was up to the customer to check that they were charged the correct amount! The story has often been - "there's a problem with the computer", "it's not updating properly" or something similar. Stated discounts for multiple buys are sometimes not applied.
I expect this could be a widespread practice, but I haven't noticed problems with larger stores, maybe they can afford better "computers". One day I may spend an hour or two filling out the rather large Trading Standards report form. In a recent purchase at a Londis
store I was overcharged at the till for a loaf of bread. When I pointed out the discrepancy the assistant smiled sweetly and said that's what it says on the till, didn't offer a refund, thus breaking trading law - training required?
It's obvious to me that in most cases this is not a genuine mistake. For one thing the price at the till is always higher
than that marked in my experience. It's organised theft. The shops rely on customers not counting up their bill, and even if they do not wanting to quibble and hold up the queue or create a fuss. Customers could be especially vulnerable at petrol stations for one example.
PS: I just heard a whisper that I'm not
"one of the best" customers of a store with poor price labelling and charging co-ordination performance. So to be "one of the best" customers one has to behave in what manner I wonder. Probably to not notice or complain about pricing discrepancies would help. Not wishing to be a sub standard customer I'll avoid this store.
Update 13 Feb 2017:
An example of what can happen reported by the BBC (I haven't noticed a problem with this store chain myself): Tesco customers overcharged by out-of-date offers
As of 14 Feb the above article has 845 comments, some criticising the BBC for pointing this out (shareholders I guess). It's not just Tesco of course. I first noticed this as a regular occurence in around 2008/9, perhaps it was no co-incidence there was a serious economic downturn at the time.
Shopping - FinancePosted by Dennis Hopkins Fri, May 13, 2016 10:52PM- but strong in making me lose money and time, wish I'd seen reviews of ParcelForce beforehand ...
I sent a largish item within size/weight limits by ParcelForce (PF), for collection at a specified Post Office. This is what happened:
1. I specified collection 0900-1400 26/4/16, it was collected 1812
2. I could not enter recipients required post office depot for delivery, only 4 presented on PF website
3. The selected post office refused to accept delivery on 27/4/16, although parcel was within weight and size restrictions
4. There was no warning on PF website of potential refusal to accept by Post Office
5. The tracking information repeatedly referred to Returned to Sender, rather than being held at a depot, seemed very keen to return rather than trying to resolve. Note the 1 minute
lapse between returning to depot and returning to sender!
6. I managed to get PF to attempt a second delivery, when this failed parcel was returned to me.
7. ParcelForce sent an email to the recipient that the parcel was ready for collection 5/5/16 10:40, was delivered to me one minute later at 10:41. It couldn't be collected, it was on a van, and no point notifying the recipient, it was being delivered back to the sender 130 miles away!
The "Force" wasn't with me here, lost money and time. Claiming for compensation looks very time consuming, all the details have to be entered again, they know all that from the parcel and invoice number, obviously an attempt to deter claims. 19/5/16UPS, via the Parcel2Go website, successfully delivered parcel on the second attempt
(when recipient wasn't available 1st time). There was no immediate decision to return to sender.
ParcelForce have denied my claim saying that the recipient refused delivery. Not correct, didn't read my claim notes, their Post Office "partner" refused delivery. To be continued-
After sending ParcelForce another message, this time with salient details in capital letters, and repeated, they say "Having reviewed the details of your appeal i have arranged to reopen and pay your claim for a postage refund". Since the details of the claim were the the same as before, they either ignored them the first time, or refused the claim on the same evidence presented when they accepted it - interesting. I wonder if they do this for every claim.
Received refund of postage only (2 months later, consequential costs refused, as expected)

About 25 years ago I found a hawthorn tree growing from a seed, dropped by a bird I guess. I transplanted it into a border, and now the trunk is about 7 inches (17 cm) diameter, but it's not very tall. With pruning and training (I'm not sure how), it's become a low pollard at about 3 feet, with dense growth to 6 feet. In the photo, the trunk is about one third from the right, branches extend to the upper left along the trellis.
This thorny tree growth is popular with birds, especially with peanut/seed feeders nearby. It gives them some protection from cats and other predators. I just trim the "hedge" section once a year, wearing heavy duty leather gloves of course. Hawthorn is relatively slow growing at this altitude (850 feet), and can be shaped by severe pruning if necessary. It usually produces flowers and berries on the previous years growth. Another bonus, it doesn't spread by producing "suckers" or from bits of stem lying on the ground, unlike blackthorn and some willows etc..
