A wee close up of stems that were in a glass on our breakfast table. I think it looks quite cool. It's only about 2-3" wide.
An article on the 25 years + since the "liquidators" faced the fires of Chernobyl news.nationalgeographic.com/news/energy/2011/04/110426/ch...
The Chernobyl disaster is widely considered to have been the worst nuclear power plant accident in history, and is one of only two classified as a level 7 event on the International Nuclear Event Scale (the other being the Fukushima Daiichi nuclear disaster in 2011). The battle to contain the contamination and avert a greater catastrophe ultimately involved over 500,000 workers and cost an estimated 18 billion rubles. The official Soviet casualty count of 31 deaths has been disputed, and long-term effects such as cancers and deformities are still being accounted for.
Shortly after the accident, firefighters arrived to try to extinguish the fires. First on the scene was a Chernobyl Power Station firefighter brigade under the command of Lieutenant Volodymyr Pravik, who died on 9 May 1986 of acute radiation sickness. They were not told how dangerously radioactive the smoke and the debris were, and may not even have known that the accident was anything more than a regular electrical fire: "We didn't know it was the reactor. No one had told us."
Grigorii Khmel, the driver of one of the fire engines, later described what happened:
We arrived there at 10 or 15 minutes to two in the morning... We saw graphite scattered about. Misha asked: "Is that graphite?" I kicked it away. But one of the fighters on the other truck picked it up. "It's hot," he said. The pieces of graphite were of different sizes, some big, some small, enough to pick them up...
We didn't know much about radiation. Even those who worked there had no idea. There was no water left in the trucks. Misha filled a cistern and we aimed the water at the top. Then those boys who died went up to the roof – Vashchik, Kolya and others, and Volodya Pravik.... They went up the ladder ... and I never saw them again.
However, Anatoli Zakharov, a fireman stationed in Chernobyl since 1980, offers a different description:
I remember joking to the others, "There must be an incredible amount of radiation here. We'll be lucky if we're all still alive in the morning."
Twenty years after the disaster, he said the firefighters from the Fire Station No. 2 were aware of the risks.
Of course we knew! If we'd followed regulations, we would never have gone near the reactor. But it was a moral obligation – our duty. We were like kamikaze.
The immediate priority was to extinguish fires on the roof of the station and the area around the building containing Reactor No. 4 to protect No. 3 and keep its core cooling systems intact. The fires were extinguished by 5:00, but many firefighters received high doses of radiation. The fire inside reactor 4 continued to burn until 10 May 1986; it is possible that well over half of the graphite burned out.
The fire was extinguished by a combined effort of helicopters dropping over 5,000 metric tons of sand, lead, clay, and neutron absorbing boron onto the burning reactor and injection of liquid nitrogen. The Ukrainian filmmaker Vladimir Shevchenko captured film footage of an Mi-8 helicopter as its main rotor collided with a nearby construction crane cable, causing the helicopter to fall near the damaged reactor building and killing its four-man crew. It is now known that virtually none of the neutron absorbers reached the core.
From eyewitness accounts of the firefighters involved before they died (as reported on the CBC television series Witness), one described his experience of the radiation as "tasting like metal," and feeling a sensation similar to that of pins and needles all over his face. (This is similar to the description given by Louis Slotin, a Manhattan Project physicist who died days after a fatal radiation overdose from a criticality accident.)
The explosion and fire threw hot particles of the nuclear fuel and also far more dangerous fission products, radioactive isotopes such as caesium-137, iodine-131, strontium-90 and other radionuclides, into the air: the residents of the surrounding area observed the radioactive cloud on the night of the explosion.
Timeline
1:26:03 – fire alarm activated
1:28 – arrival of local firefighters, Pravik's guard
1:35 – arrival of firefighters from Pripyat, Kibenok's guard
1:40 – arrival of Telyatnikov
2:10 – turbine hall roof fire extinguished
2:30 – main reactor hall roof fires suppressed
3:30 – arrival of Kiev firefighters
4:50 – fires mostly localized
6:35 – all fires extinguished
With the exception of the fire contained inside Reactor 4, which continued to burn for many days.
In the city of Chernobyl there stands a simple memorial to the liquidators who rushed to reactor number four in the immediate aftermath of the explosion. The firefighters who initially responded to the disaster on the morning of April 26, 1986 were unaware that they were entering a radioactive environment, and rushed to the plant without donning protective suits and respirators. While they labored to extinguish the fires, their bodies absorbed lethal doses of radiation, and many of them later died of Acute Radiation Sickness. Overall, some 600,000 workers, including scientists, miners, and Soviet military conscripts, participated in the Chernobyl cleanup efforts. To this day, many of them continue to experience a variety of health problems stemming from their time spent in the zone. The plaque on the monument is inscribed “To those who saved the world.”

Some new faces, some old, made new friends and generally we were in our elements.
Rhetorical question but did we have a blast? You bet!
Amazing group, top guys. Till the next time!

Once in a while, we will have an invasion by an alien force that swarm through all our defenses. We were fooled by their disguise, their cuteness and let our guards down. Before we know it, they are everywhere – in the bags we carried, the clothes that we wore, dangling from key chains, hanging from ceilings, there is no stopping them.
First, they stole our children’s heart, then their grannies’ pockets. They decimated our adult’s time and ate at their mind till they yelped at high scores and mourned when they could not bring a building down. They made them into zombies that could only move their fingers to pull at illusionary catapult to send angry birds flying. And crashing. And the monkeys have the last laugh.
I belong to the special force that tried to stem this invasion. I found some angry birds taking hold in a small town called Bidor in Malaysia that is famed for their herbal duck soup. Their evil scheme here was to take over the gastronomy delight of this small town and I was sent to disrupt their plan of conquest. So I did my part to reduce the population of angry birds there by eating them! But there are just too many. I tried my best and live to talk about it. I don’t know about you but I find angry birds rather yummy.

Using the main stem piece as a template to shape the 2 doublers. A pattern routing bit (with a bearing) is used.
Having gone to all this trouble, consider now whether you want to make an outer stem to cover the ends of your boards. If you do it is good to prepare for the making of the pattern now while you have the stem available to trace from easily. It is more simple to mold the curves of the stem on a bench than on the boat in my opinion, so I traced the outline of this piece onto some stout ply, and this will eventually support the mold pieces for the lamination of outer stem layers. Put the piece of ply away carefully and don't let anyone tidy it up because it may be months before you get around to making the outer stem.
