This WW1 memorial plaque, 5 inches (120mm) in diameter, known familiarly as "Dead Man's Penny" due to a superficial resemblance to the much smaller penny has been set into this stone by, presumably Thomas Bevan's parents who died in 1939 and 1943. 1,355,000 of these were struck and presented to the families of all servicemen killed in WW1. Designed by Edward Carter Preston and entitled "Pyramus", it depicts Britannia offering a wreath of laurel leaves to the deceased's name, with two dolphins representing Britain's maritime power. In the exergue, under the main lion, another lion is devouring a German eagle. Preston's initials are over the lion's paw. Rank was deliberately omitted to represent equal sacrifice. This is an earlier version produced in 1919 before production moved to Woolwich. Early models have no number behind the lion's rear leg.
St Martin's is buried deep in the Monmouthshire countryside some seven miles north of Abergavenny, above the river Honddu. The church is known, with justification, as "the crooked church" due to the crazy angles which parts of the structure skew from each other. It dates back to at least the Middle Ages and a dedication to St Martin is not common. The church, with another St Martin's at Bwlch Trewyn (now completely vanished without trace) is on the old pilgrimage route to St David's in Pembrokeshire (two pilgrimages to St David's equated to one pilgrimage to Rome).The church owes its crooked appearance to having been built on a landslip; Cwmyoy (Cwmiou, Cwm Iau) derives its name from the Welsh for "yoke", the landslip in the hill above leaving a yoke shape in the terrain. Legend has it that the landslip occurred at the time of the crucifixion. The tower leans 5.2 degrees out of perpendicular (the Leaning Tower of Pisa is 4.7 degrees).
Of interest are various monuments and the 13th/14th Century cross in the nave. This is unusual in that it shows Christ wearing a bishop's mitre. It is believed to have been one of the crosses marking the Pilgrims' Way to St David's. It was discovered buried on a nearby farm in 1861 and set up in the farm garden, being transferred to the tower inside the church in 1935. In 1967 it was stolen, but identified in an antiques shop in London and restored to the church where it is now set in concrete.
There is a simple font inside by the entrance , and in the churchyard, a mediaeval preaching cross.

Very charming small puzzles. Excellent condition.
From the box:
The son of a Flemish painter, Jodocus de Momper was born in the second half of the 16th century and painted in the tradition of the Breughels. His models were the Flemish peasants among whom he lived and whose lives and their countryside he recorded. He was elected Master of the Antwerp Guild and the town of Antwerp frequently features his works.
The Four Seasons featured as individual jigsaws in this box are amongst his most highly thought of paintings, and after nearly four centuries, their colourful canvases are as alive as when they were painted.
This 12 inch diameter Rand McNally World Portrait Globe dates from 1977, and features a full mount. It is very rare in that it shows the Central African Empire, which as a country only existed from 1976 - 1979. (It is now known as the Central African Republic).
According to Wikipedia, the Central African Empire was the name of the short-lived, self-declared autocratic monarchy that replaced the Central African Republic and was, in turn, replaced by the restoration of the republic. The Empire was formed in December 1976, and the name "Central African Republic" was restored in September of 1979.
This globe is also unique because of the full mount stand, which features two full circular axes and a separate metal semi-circle base.

A 27.5x3” tire measures out to a 29” diameter and a 26x3” tire measures out to a 27.5” diameter. Combining them with a 40mm rim, results in the ultimate combination of traction, roll-over and versatility without being too heavy, too bouncy, too tall or feeling lethargic on the trail.
REYNOLDS 520 STEEL
For well over a century, Reynolds has been at the forefront of cycling design and engineering continually pushing the boundaries of performance. The 520 series double-butting provides both strength and weight savings resulting in a smooth riding frameset.
44MM HEAD TUBES
Oversized 44mm head tubes, like tapered head tubes, offer many advantages impacting the handling and performance of the bike. Not only do they allow for the use of tapered steerer forks adding more stiffness, lighter weight and better tracking in rough terrain, but the larger diameter provides a better surface area to weld the main triangle tubes to.
ADJUSTABLE SLIDING DROPOUTS
Our sliding dropout allows for 15mm of adjustment. Slide your rear wheel back to increase clearance for larger tires or remove all those gears and shifters and simply tension your chain for a quiet single speed ride.
READY TO LOAD
The Dragonslayer and Dragonfly frames feature rear rack eyelets and enough cargo/water cage mounts for the option to load up all the gear you may possibly need out there. Full cable housing guides are used to ensure uninterrupted shifting performance when using a frame bag.
OUTBOARD CHAIN LINE
A 12x148 rear hub with 3mm offset chainrings minimizes the chance of chain to tire contact with short chainstays and “mid-fat” tires without compromising any pedaling efficiency to a wider q-factor.
TUBELESS
Benefits of a tubeless set-up are reduced rotating weight and the ability to use lower inflation pressures for greater traction without the risk of pinch flats. WTB TCS rims feature a tubeless UST “On-Ramp” profile providing a consistent fit between the rim and the tire for easy installation and inflation.

A large 2ft diameter circular puzzle cut from a contemporary travel poster for the A1 Puzzle Club of Liverpool in the 1920’s. It is 500 pieces, cut by Mrs Thompson for the club in an interlocking loopy style with considerable colour-line cutting particularly of the girl in the foreground.
The A1 puzzle Club flourished in the 1920’s and 1930’s with a large circulation base in both the north and south of the country. The Liverpool base was run by a Mrs O’Brien, their southern base was in Acton Vale, London. They tended to use local puzzle cutters and many of their puzzles are quite splendid, but later they incorporated puzzles from Chad Valley and Hayter, so you need to be vigilant when buying this puzzle club. Their original huge square boxes rarely survive as the brown card contained a lot of acid. This puzzle was re-housed in a replacement box in 1927 but thankfully retained the important lid top. "

This was taken with a Canon 30D with the 50mm f/1.8 lens, a Raynox DCR-250 macro lens attachment, and Photophool's CCRRFD-Ufp.v0 device for close up flash attenuation, simulates ring-light.
Now that I have Photophools gadgets for doing macro photography with the Raynox DCR-250, I decided to see what I could do with them on my Canon 30D. I chose the Canon 50mm f/1.8 lens(already on hand). This lens is very inexpensive, but has a great reputation and a perfect fit for the Raynox. For about $150 you can be taking nice ring-light simulated flash macros.
I am able to switch between the Canon SX10 and the 30D in the blink of the eye...due to the quick disconnect of the Raynox adapter
This isn't a super prime shot...but I'm just getting started..

Ron Moore hand-cuts tiny pieces in a neat, precise geometric style. He uses his mathematical & computer skills to create and deform a complex geometric grid which he uses as a cutting template. With selected images, such as this blue & white chrysanthemum Japanese origami paper, he can make puzzles of tailored difficulty. Ron includes his signature turtle piece at the centre of his circular puzzles.

Top Left & Lower Left: Turtleteasers 151pc Blue Chrysanthemums, 6in diameter 2012. Received by Terry Walters at the 2012 Pagey Elliott Puzzle Exchange. You can see that the jigsaw is divided into six segments, but the cutting is fairly uniform across them.
Top Right: Turtleteasers 55pc Blue Chrysanthemum, 4in diameter. This doesn't seem to have been divided into segments, but worked in rings. (Post script - looking closer I can see the segments!)
Centre Right: Turtleteasers 151pc Blue Chrysanthemum, 6in diameter cut May 2017. This example has more obvious pie slices or six segments which change as you go around the circle, the piece shapes morphing into each other. The pieces are more varied and distinctive making the jigsaw easier to do.

John Stokes page linking his reviews of all the 2012 PEPE jigsaws:
www.custompuzzlecraft.com/PuzzleMakers/2012puzzleexchange...
John Stokes says: "I found Japanese Blue Chrysanthemums to be by far the most difficult of the non-trick Parley Exchange puzzles to assemble. Took me several hours in the wee of the night to do it. This particular puzzle is basically just blue and white and since the pieces are small I found for some areas of the puzzle, the fairly uniform distribution of white and blue on the pieces made it very difficult to find a matching piece by color alone, rather I had to focus on the shape. Adding injury to insult (lol), Ron wrote: You were fortunate in that from your email I can deduce that you had one of the "easy" ones. The easy puzzles had quite a variety of piece shapes, specifically there were 4 distinct edge cuts, plus their inverses. The difficult versions had a single type of edge cut (plus the single inverse), so they were quite a bit more tricky. For someone who wants a nice difficult puzzle to solve, this one is for you."
I can confirm that this 151pc jigsaw is indeed very difficult! It took me three or four sessions, and I think it is probably more difficult than the larger 8in diameter puzzle I own, which you can see above. I think it is also one of the less difficult versions of the puzzle - there being several different edge piece shapes.

Looks like the 22.5" diameter of the WWII Mk 13 (Mk Xiii) air-launched torpedo but the fins (too narrow) and fin ring (present) are not typical Mk 13 parts. Mk 13's 161" length seems plausible. Mk 21 Mod 0 and Mod 2 had the same 22.5 X 161" dimensions as did Mk 25, but only the Mk 21 mod 2 was mass produced.
The round skull of the fetus is seen, and the diameter is measured. Note the formation of ‘arrow like sign’ inside the skull. It is when this sign appears that the BPD is measured.

This small dish about 7 cm diameter has a shape so delicately made and glazed all over except 3 very small spur marks in the bottom. The foot ring was fully glazed and appears nearly black which is not common in Ju wares but more common in northern Song Guan ware.
This dish apparrently was made for the court but seemed over fired and was left to the civil market and used for certain purpose and bear marks of severe wearing.

Fracastorius Crater - A remnant of the original crater with it's northern wall missing is the primary target in this image. The lava flow that resulted in the formation of Mare Nectaris intruded into Fracastorius giving it a bay-like appearance. This angle of sunlight makes apparent the mounds that appear to be the remnants of the crater rim that was either destroyed, or overlaid by lava. The diameter of Fracastorius is 75 miles and the depth varies due to it's angle, most apparent as you approach the southern rim. Fracastorius D lies on the western rim and is 17.3 miles in diameter.

(See links). Meteor Crater is a meteorite impact crater about 37 mi east of Flagstaff and 18 mi west of Winslow in the northern Arizona desert of the United States. It was designated a National Natural Landmark in November 1967.
Diameter: 0.737 miles
Depth: 560 feet
The size of the asteroid that produced the impact is uncertain—likely in the range of 100 to 170 feet (30 to 50 meters) across—but it had to be large enough to excavate 175 million metric tons of rock.
The crater was created about 50,000 years ago. The crater came to the attention of scientists after American settlers encountered it in the 19th century. In 1903, mining engineer and businessman Daniel M. Barringer suggested that the crater had been produced by the impact of a large iron-metallic meteorite. During the 1960s and 1970s, NASA astronauts trained in the crater to prepare for the Apollo missions to the Moon.
Meteor Crater - Wikipedia
Meteor Crater is a popular tourist attraction privately owned by the Barringer family through the Barringer Crater Company, with an admission fee charged to see the crater. The Meteor Crater Visitor Center on the north rim features interactive exhibits and displays about meteorites and asteroids, space, the Solar System, and comets. It features the American Astronaut Wall of Fame and such artifacts on display as an Apollo boilerplate command module (BP-29), a 1,406 lb meteorite found in the area, and meteorite specimens from Meteor Crater that can be touched. Formerly known as the Museum of Astrogeology, the Visitor Center includes a movie theater, a gift shop, and observation areas with views inside the rim of the crater. Guided tours of the rim are offered daily, weather permitting.

With the height of 112.5 meters and diameter of 100 meters, Tempozan Harbor Village Ferris wheel was once the largest Ferris wheel in the world.Tempozan Harbor Village Ferris wheel was surpassed by London Eye when it opened to public in 1999, however, some argues that London Eye is actually an observation wheel which is considered to be another kind of wheel and shouldn't be counted in the Ferris wheel ranking. Nevertheless, some newcomers like Palette Town Ferris wheel (opened in 1999, located in Odaiba, Tokyo, with same diameter as Tempozan, but 2.5 meters more in total height), Sky Dream Fukuoka (opened in 2002, with 112 meters in diameter and 120 meters in total height), or the Diamond and Flower Ferris wheel of Kasai Rinkai Park, east of Tokyo (opened in 2005, 111 meters in diameter and 117 meters in height), exceeded Tempozan with small margins.
The Ferris wheel was opened to public on July 12, 1997. During its 17-minute ride, it offers a view of Osaka Bay and surrounding areas, such as Ikoma Mountains to the east, Akashi Strait Pearl Bridge to the west, Kansai International Airport to the south, and Rokko Mountains to the north.
The wheel has colored lights that provide a weather forecast for the next day. Orange lights indicate a sunny day, green lights a cloudy day and blue lights indicate rain.
The Tsar Bell, or Royal Bell, is a 200-ton, 6.6-metre diameter bell on display on the grounds of the Moscow Kremlin. Pictures from Moscow, Russia in May 2011. I stopped here for one day before continuing my flights to a conference in StPetersburg. In spite of the rain, I managed to visit the most of the Kremlin sites in the morning.
A Cár Harang a Kreml közepén Moszkva belvárosában 2011. májusában. Az orosz könyveimből ismert harang 200 tonnát nyom, már az öntés után egy tűzben letört róla egy 11 tonnás darab, és közel száz évig az öntőgödörben maradt. Egy napot töltöttem Moszkvában, mielőtt továbbrepültem Szentpétervárra egy konferenciára. Az esős idő ellenére sikerült a Kreml jelentős részét megnéznem a délelőtti órákban.
The Tsar Bell was commissioned by Empress Anna Ivanovna, niece of Peter the Great in 1735. Made of bronze, the bell was broken during metal casting and has never been rung. The bell is currently the largest bell in the world, weighing 201,924 kilograms (445,166 lb), with a height of 6.14 metres (20.1 ft) and diameter of 6.6 metres (22 ft), and thickness of up to 61 centimetres (24 in). The broken piece weighs 11,500 kilograms (25,400 lb). The bell is decorated with relief images of baroque angels, plants, oval medallions with saints, and nearly life-size images of Empress Anna and Tsar Alexey, who was reigning at the time the previous Tsar Bell was cast. The original Tsar Bell, cast in the 15th century, was completed in 1600, weighed 18,000 kg and required 24 men to ring its clapper. Housed in the original wooden Ivan the Great Bell Tower in the Moscow Kremlin, it crashed to the ground in a fire in the mid-17th century and was broken to pieces. The second Tsar Bell was cast in 1655, using the remnants of the former bell, but on a much larger scale. This bell weighed 100,000 kg, but was again destroyed by fire in 1701. After becoming Empress, Anna ordered that the pieces be cast into a new bell with its weight increased by another hundred tons. In 1733, the job was assigned to local foundry masters, Ivan Motorin and his son Mikhail, based on their experience in casting a bronze cannon. A 10-meter deep pit was dug (near the location of the present bell), with a clay form, and walls reinforced with rammed earth to withstand the pressure of the molten metal. Obtaining the necessary metals proved a challenge, for in addition to the parts of the old bell, an additional 525 kilograms of silver and 72 kilograms of gold were added to the mixture. After months of preparation, casting work commenced at the end of November 1734. The first attempt was not successful, and the project was incomplete when Ivan Motorin died in August, 1735. His son Mikhail carried on the work, and the second attempt at casting succeeded on November 25, 1735. Ornaments were added as the bell was cooling while raised above the casting pit through 1737. However, before the last ornamentation was completed, a major fire broke out at the Kremlin in May 1737. The fire spread to the temporary wooden support structure for the bell, and fearing damage, guards threw cold water on it, causing eleven cracks, and a huge (11.5 tons) slab to crack off. The fire burned through the wooden supports, and the damaged bell fell back into its casting pit. The Tsar Bell remained in its pit for almost a century. Unsuccessful attempts to raise it were made in 1792 and 1819. Napoleon Bonaparte, during his occupation of Moscow in 1812, considered removing it as a trophy to France, but was unable to do so, due to its size and weight. It was finally successfully raised in the summer of 1836 by the French architect Auguste de Montferrand and placed on a stone pedestal. The broken slab alone is nearly three times larger than the world's largest bell hung for full circle ringing, the tenor bell at Liverpool Cathedral. For a time, the bell served as a chapel, with the broken area forming the door.
The recommended size for logs is 3 to 4 feet long and 4 to 7 inches in diameter (manageable to lift and move, especially if moist). Most hardwood tree species will suffice, but some, such as oak because of its density, are better than others. Conifers are not suitable. Logs are usually cut in the late winter or spring before buds swell. Photo: John Haworth

This is 7.5" in diameter and 1.5" tall and made of black mesquite wood. I've come to really like the water-based polyurethane finish and this has six coats of that all rubbed out like my other bowls. The poly can be recoated in just two hours so it's possible to get all the coats on in a day or two. I let it dry for 24 hours before rubbing. This bowl is the first thing I've made that I feel is as good as I can do at this stage in my woodturning. I'll never be a Bob Stocksdale but at last I'm pleased.

Working out of a studio beside her home in South Melville, PEI, Jamie Germaine produces both wheel-thrown and hand-built pieces with a unique style of textured surfacing that has become characteristic of her work. Her surrounding environment of woodland and sea is reflected in the organic nature of the surfaces she creates on her pieces. She has recently been experimenting with the subtle effects of smoke firing on hand-built bowls. She has studied pottery in New York, Vermont, Prince Edward Island, Mexico and Italy and has exhibited in Prince Edward Island and New York. Her works are currently available at bestofpei in Charlottetown and at The Studio Gallery in Victoria.
This particular piece was hand built from slabs of stoneware clay. When the sphere was leather-hard, additional clay was added to create texture through incising, carving and stamping. After bisque firing, the exterior of the piece was rubbed with iron oxide then fired to cone 6.

A visit to Malvern Flea Fair can often result in an interesting puzzle find; this Sunday was no exception.
Wandering among the stalls I spotted a box on the ground: it contained a hodge-podge of jigsaws, both card and wood, mostly spilling out into the box and not really of interest.
And then I saw this old, battered Waddingtons box... stuffed inside was an assortment of brown envelopes. Pulling one out, I noticed it had a 1941 postmark and contained a few puzzle pieces. Hmmm... my curiosity was piqued... what could this be? A quick negotiation with the seller and I was the owner of this mystery object.
So yesterday (Monday) I settled down to find out more. Tipping out the contents of the box I found there were eight envelopes, each containing a handful of jigsaw pieces, mostly addressed to one person, and showing signs of having been re-used during World War II when paper was in short supply. They had George VI stamps and 1941/2 postmarks so I was handling (at least) 80 year old puzzle pieces. Each envelope was carefully labelled with a description of the pieces inside.
Carefully opening each envelope, I assembled the pieces and laid them aside. When I'd finished I could see that they made up the puzzle shown on the Waddingtons box, and it was complete.
But why would they have been posted in sections to the people on the envelopes? Was this some sort of wartime puzzle swapping club? And why send small sections instead of the whole puzzle? I shall probably never know...
Diameter: cca 30 / 22 / 16 cm. Blown in transparent or coloured glass, without mould, cut, grinded and polished.
Belongs to the article I wrote about Anna in my Modern Home Design section.
Diameter 8 mm. Adult, no longer with juvenile Maltese cross outline and grey furrows on the wall plates, but four distinct wall plates retained, and a low profile with blackish triangles on the scuta. The terga and tergoscutal flaps are obscured by brown algae. When the rostrum edge is indented (1) the outline of the operculum is a blunt diamond shape.

The way the tower's diameter flares out a bit at the bottom, which is called a batter, was an innovation that came in at around the time this castle was built and helps date it. A sign at the castle tells you that battered walls "lessened the impact of battering rams and deterred mining, and also provided greater wall thickness, the angle of the wall also serving to keep assailant’s ladders away from it and so more exposed to missiles fired from above".
While all that is undoubtedly true to a greater or lesser extent, my understanding was always that a rock or similar missile dropped down a vertical wall either lands on someone's head or more likely embeds itself in the ground, whereas a rock dropped down a wall with a batter shoots off horizontally at the bottom, with much greater opportunity for doing damage in the process! The 'battered' tower seen here is the Comyn Tower at the north-west angle.
Also visible in this photo is a low and rather sorry looking wall on the left, behind which the gravel path disappears, which is all that remains of the north (external) gatehouse, the principal purpose of which would have been to provide access to the river - a water gate. The equally sorry looking wall to the right, along the line of trees, I suspect has something to do with the jetty. The meadow to the right may well have been water 700 years ago.

Steph measured me and determined this to be the best size for my homemade hoop. We had a HILARIOUS time trying to figure out the circumference, in which we both forgot the equation for circumference (confusing it with area) and coming out with numbers that made NO SENSE. Luckily we are both sensible people and we didn't cut 1000+ inches of hoop for me, figuring it out before ratcheting pliers were taken to the piping.
also--here's a PSA regarding picking a hoop size. I'm several inches shorter than Steph so my hoop is 2" less in diameter--and it feels a LOT more comfortable to use than hers does when I play with it. So if you're starting out, measure well! We went with a number about one inch greater than the distance from the floor to my belly button.
**Good**
1. Aluminum rigidity, flexibility, strength at 19mm diameter. 25mm diameter might be better. Moderate Flexibility is good
2. One person operation
3. Thrust is good underwater
4. Faster setup
5. Stability is good
**Bad**
1. One engine did not go!
2. The camera needs to be deeper and blacked out
3. The camera and brain needs to be cooled
4. In reverse cables get wet(short circuit)
5. Better, faster attachments for tubes
6. Better attachments for tubes, rudders, to stay vertical
7. Set tubes further apart for more stability

TAXONOMY
Kingdom: Animalia
Phylum: Echinodermata
Class Asteroidea
Order: Forcipulatida
Family: Asteriidae
Genus/species: Pisaster brevispinus
GENERAL CHARACTERISTICS The pink sea star reaches a maximum diameter of nearly 65 cm (2 ft); however, individuals are usually smaller. Its central disc has a raised, humplike appearance. They are robust, pink in color and have aboral spines much shorter than those of other Pisaster species, thus its scientific name, which translates as "short-spined sea star."
DISTRIBUTION/HABITAT They range from Sitka, Alaska to San Diego County, California. They can occasional be seen in the low intertidal zone, but are more commonly found in deeper water to 90 m (300 ft ) on sand and mud substrates, but sometimes on rocks and pier pilings in calm waters. They cannot tolerate prolonged exposure to air.
DIET IN THE WILD: Pink sea stars prey on live clams, snails, sand dollars, barnacles, mussels, tubedwelling annelid worms, and scavenge on dead fish and squid. On soft surfaces, P. brevispinus digs into sand or mud with its arms. It also can extend its tube feet (the ones around its disk) to a length of 20 cm (8 in). When the tube feet reach a clam buried in the mud, they attach and the sea star hauls it up. On shale, it can lower its stomach into the burrow of a clam and digest the animal in place. Their large size may well be due to their access to a plentiful food supply of large organisms unavailable to potential competitors.
PREDATORS Large adults have few predators, but they may be taken by the sunflower sea star Pycnopodia helianthoides. Sea otters have been known to detach rays to consume gonads, and
sea gulls occasionally feed on individuals exposed during very low tides.
REPRODUCTION They spawn in the spring. Sexes are separate and fertilization takes place externally. Larvae disperse in the water column. Pink stars can live up to 20 years.
REMARKS: Can chemosense clams through sand. May dig down to the clam for 2 –3 days or extend tube feet to the clam a distance equal to the arm radius to 20 cm (7.8 in). Once contacted,the clam is lifted from the substrate or the stomach may be everted to 8 cm (3.15 in) to digest the prey in place. Some sand-bottom invertebrates including the sand dollar Dendraster excentricus and the snail Olivella biplicata chemosense the presence of a pink star and attempt to avoid contact by burrowing.
