All sizes please!
This an illustration of the firing mechanism I implemented in my DX CSWS, called 2DBolt. Main advantage of this system, is that there is more room for the barrel, without making the whole gun longer.
2DBolt:
-2 parts of instead of one are moving
-bolt moves in 2 dimensions (along the 'barrel line' and up/down)
Because of the fragility, system is isolated from the environment - caseless ammo eliminates need for ejection port and magazine with piston (see notes) seal it completely.
Arrows shows the resemblance to a bolt-action system (also, it is possible that 2DBolt is moved with a lever, not with electronics - then the arrows show the moving pattern)
If you wan't, you can use it, just credit me for the idea.
3D printed molds and cores for the foundry industry are now a reality. Hazleton Casting Company in Eastern Pennsylvania can now offer fast-turnaround castings without expensive hard tooling to its specialty equipment manufacturers thanks to the RAM System by Viridis3D.

Using a patent-pending technology, a proprietary print head attached to an ABB robot arm uses exclusive binder jetting technology to print sand molds and cores for the foundry industry. The proprietary system includes easy-to-use software that uses a CAD file to print a mold and core in just a few hours.
Foundries will appreciate the speed with which the system prints — and how fast their operation can be up and running with the new technology. What’s more, the RAM 123 uses less sand and is substantially less expensive than other sand casting 3D printers on the market today.
This disruptive technology brings a new way of production to foundries — instead of shipping castings around the world, raw materials are shipped and files are simply transmitted to 3D printers in strategic locations. The result is castings are poured the same day, only where you need them.

The Notre-Dame Fire
On the 15th. April 2019, fire broke out in the attic beneath the cathedral's roof at 18:18. At 18:20 the fire alarm sounded and guards evacuated the cathedral. A guard was sent to investigate, but to the wrong location – the attic of the adjoining sacristy – where he found no fire. About fifteen minutes later the error was discovered, but by the time guards had climbed the three hundred steps to the cathedral attic the fire was well advanced.
The alarm system was not designed to automatically notify the fire brigade, which was summoned at 18:51 after the guards had returned. Firefighters arrived within ten minutes.
Fighting the Notre-Dame Fire
More than 400 firefighters were engaged. A hundred government employees along with police and municipal workers moved precious artefacts to safety via a human chain.
The fire was primarily fought from inside the structure, which was more dangerous for personnel, but reduced potential damage to the cathedral - applying water from outside risked deflecting flames and hot gases (at temperatures up to 800 °C) inwards. Deluge guns were used at lower-than-usual pressures to minimise damage to the cathedral and its contents. Water was supplied by pump-boat from the Seine.
Aerial firefighting was not used because water dropped from heights could have caused structural damage, and heated stone can crack if suddenly cooled. Helicopters were also not used because of dangerous updrafts, but drones were used for visual and thermal imaging, and robots for visual imaging and directing water streams. Molten lead falling from the roof posed a special hazard for firefighters.
By 18:52, smoke was visible from the outside; flames appeared within the next ten minutes. The spire of the cathedral collapsed at 19:50, creating a draft that slammed all the doors and sent a fireball through the attic. Firefighters then retreated from within the attic.
Shortly before the spire fell, the fire had spread to the wooden framework inside the north tower, which supported eight very large bells. Had the bells fallen, it was thought that the damage done as they fell could have collapsed the towers, and with them the entire cathedral.
At 20:30, firefighters abandoned attempts to extinguish the roof and concentrated on saving the towers, fighting from within and between the towers. By 21:45 the fire was under control.
Adjacent apartment buildings were evacuated due to concern about possible collapse, but on the 19th. April the fire brigade ruled out that risk. One firefighter and two police officers were injured.
Damage to Notre-Dame
Most of the wood/metal roof and the spire of the cathedral was destroyed, with about one third of the roof remaining. The remnants of the roof and spire fell atop the stone vault underneath, which forms the ceiling of the cathedral's interior. Some sections of this vaulting collapsed in turn, allowing debris from the burning roof to fall to the marble floor below, but most sections remained intact due to the use of rib vaulting, greatly reducing damage to the cathedral's interior and objects within.
The cathedral contained a large number of artworks, religious relics, and other irreplaceable treasures, including a crown of thorns said to be the one Jesus wore at his crucifixion. Other items were a purported piece of the cross on which Jesus was crucified, the Tunic of St. Louis, a pipe organ by Aristide Cavaillé-Coll, and the 14th.-century Virgin of Paris statue.
Some artwork had been removed in preparation for the renovations, and most of the cathedral's sacred relics were held in the adjoining sacristy, which the fire did not reach; all the cathedral's relics survived. Many valuables that were not removed also survived.
Lead joints in some of the 19th.-century stained-glass windows melted, but the three major rose windows, dating back to the 13th. century, were undamaged. Several pews were destroyed, and the vaulted arches were blackened by smoke, though the cathedral's main cross and altar survived, along with the statues surrounding it.
Some paintings, apparently only smoke-damaged, are expected to be transported to the Louvre for restoration. The rooster-shaped reliquary atop the spire was found damaged but intact among the debris. The three pipe organs were not significantly damaged. The largest of the cathedral's bells, the bourdon, was also not damaged. The liturgical treasury of the cathedral and the "Grands Mays" paintings were moved to safety.
Environmental Damage
Airparif said that winds rapidly dispersed the smoke, carrying it away aloft along the Seine corridor. It did not find elevated levels of particulate air pollution at monitoring stations nearby. The Paris police stated that there was no danger from breathing the air around the fire.
The burned-down roof had been covered with over 400 metric tons of lead. Settling dust substantially raised surface lead levels in some places nearby, notably the cordoned-off area and places left open during the fire. Wet cleaning for surfaces and blood tests for children and pregnant women were recommended in the immediate area.
People working on the cathedral after the fire did not initially take the lead precautions required for their own protection; materials leaving the site were decontaminated, but some clothing was not, and some precautions were not correctly followed; as a result, the worksite failed some inspections and was temporarily shut down.
There was also more widespread contamination; testing, clean-up, and public health advisories were delayed for months, and the neighbourhood was not decontaminated for four months, prompting widespread criticism.
Reactions to the Notre-Dame Fire
President of France Emmanuel Macron, postponing a speech to address the Yellow Vests Movement planned for that evening, went to Notre-Dame and gave a brief address there. Numerous world religious and government leaders extended condolences.
Through the night of the fire and into the next day, people gathered along the Seine to hold vigils, sing and pray.
White tarpaulins over metal beams were quickly rigged to protect the interior from the elements. Nettings protect the de-stabilised exterior.
The following Sunday at Saint-Eustache Church, the Archbishop of Paris, Michel Aupetit, honoured the firefighters with the presentation of a book of scriptures saved from the fire.
Investigation Into The Notre-Dame Fire
On the 16th. April, the Paris prosecutor said that there was no evidence of a deliberate act.
The fire has been compared to the similar 1992 Windsor Castle fire and the Uppark fire, among others, and has raised old questions about the safety of similar structures and the techniques used to restore them. Renovation works increase the risk of fire, and a police source reported that they are looking into whether such work had caused this incident.
The renovations presented a fire risk from sparks, short-circuits, and heat from welding (roof repairs involved cutting, and welding lead sheets resting on timber). Normally, no electrical installations were allowed in the roof space due to the extreme fire risk.
The roof framing was of very dry timber, often powdery with age. After the fire, the architect responsible for fire safety at the cathedral acknowledged that the rate at which fire might spread had been underestimated, and experts said it was well known that a fire in the roof would be almost impossible to control.
Of the firms working on the restoration, a Europe Echafaudage team was the only one working there on the day of the fire; the company said no soldering or welding was underway before the fire. The scaffolding was receiving electrical supply for temporary elevators and lighting.
The roofers, Le Bras Frères, said it had followed procedure, and that none of its personnel were on site when the fire broke out. Time-lapse images taken by a camera installed by them showed smoke first rising from the base of the spire.
On the 25th. April, the structure was considered safe enough for investigators to enter. They unofficially stated that they were considering theories involving malfunction of electric bell-ringing apparatus, and cigarette ends discovered on the renovation scaffolding.
Le Bras Frères confirmed its workers had smoked cigarettes, contrary to regulations, but denied that a cigarette butt could have started the fire. The Paris prosecutor's office announced on the 26th. June that no evidence had been found to suggest a criminal motive.
The security employee monitoring the alarm system was new on the job, and was on a second eight-hour shift that day because his relief had not arrived. Additionally, the fire security system used confusing terminology in its referencing parts of the cathedral, which contributed to the initial confusion as to the location of the fire.
As of September, five months after the fire, investigators thought the cause of the fire was more likely an electrical fault than a cigarette. Determining the exact place in which the fire started was expected to take a great deal more time and work. By the 15th. April 2020, investigators stated:
"We believe the fire to have been
started by either a cigarette or a
short circuit in the electrical system".
Reconstruction of Notre-Dame Cathedral
On the night of the fire Macron said that the cathedral, which is owned by the state, would be rebuilt, and launched an international fundraising campaign. France's cathedrals have been owned by the state since 1905, and are not privately insured.
The heritage conservation organisation Fondation du Patrimoine estimated the damage in the hundreds of millions of euros, but losses from the fire are not expected to substantially impact the private insurance industry.
European art insurers stated that the cost would be similar to ongoing renovations at the Palace of Westminster in London, which currently is estimated to be around €7 billion.
This cost does not include damage to any of the artwork or artefacts within the cathedral. Any pieces on loan from other museums would have been insured, but the works owned by the cathedral would not have been insurable.
While Macron hoped the cathedral could be restored in time for the 2024 Paris Summer Olympics, architects expect the work could take from twenty to forty years, as any new structure would need to balance restoring the look of the original building, using wood and stone sourced from the same regions used in the original construction, with the structural reinforcement required for preventing a similar disaster in the future.
There is discussion of whether to reconstruct the cathedral in modified form. Rebuilding the roof with titanium sheets and steel trusses has been suggested; other options include rebuilding in the original lead and wood, or rebuilding with modern materials not visible from the outside (like the reinforced concrete trusses at Reims Cathedral).
Another option would be to use a combination of restored old elements and newly designed ones. Chartres Cathedral was rebuilt with wrought iron trusses and copper sheeting after an 1836 fire.
French prime minister Édouard Philippe announced an architectural design competition for a new spire that would be:
"Adapted to the techniques
and the challenges of our era."
The spire replacement project has gathered a variety of designs and some controversy, particularly its legal exemption from environmental and heritage rules. After the design competition was announced, the French senate amended the government's restoration bill to require the roof to be restored to how it was before the fire.
On the 16th. July, 95 days after the fire, the law that will govern the restoration of the cathedral was finally approved by the French parliament. It recognises its UNESCO World Heritage Site status and the need to respect existing international charters and practices, to:
"Preserve the historic, artistic and architectural
history of the monument, and to limit any
derogations to the existing heritage, planning,
environmental and construction codes to a
minimum".
On the 15th. April 2020, Germany offered to restore some of the large clerestory windows located far above eye level with three expert tradesmen who specialize in rebuilding cathedrals. Monika Grütters, Germany's Commissioner for Culture was quoted as saying that her country would shoulder the costs.
As of the 30th. November all of the tangled scaffolding was removed from the spire area, and was therefore no longer a threat to the building.
The world will now have to wait for Notre-Dame de Paris to be restored to its former magnificence.

For thousands of years, particles of sand from the San Bernardino Mountains and Indio Hills washed into the Coachella Valley, forming a system of dunes.
Today, these dunes are part of the Coachella Valley Preserve System, a 20,000-acre sanctuary that is home to several species of increasingly rare wildlife. The Coachella Valley fringe-toed lizard depends on this unusual blowsand desert for survival, and "swims" through the sand to escape predators or summer heat on the desert surface.
Four other unique wildlife species can also be found here: the Coachella roundtailed ground squirrel, the giant red velvet mite, the flat-tailed horned lizard and the giant palm-boring beetle.
The Coachella Valley Preserve also contains several palm oases, formed because San Andreas Fault lines allow water flowing underground to rise to the surface. The spectacular Thousand Palms Oasis includes a mile-long trail that winds past pools containing endangered desert pupfish. Native vegetation includes creosote bush, burrobush, smoke tree and desert lavender, part of this area's unique habitat for wildlife.

For those interested, this is our rain barrel system. We took video to explain it, haven't gotten around to editing it yet.
We have 7-55 gallon barrels all hooked together. They fill at the same time and drain together. We have one spigot to fill watering cans and a pump with another spigot for use with the hose or sprinkler.
There's an overflow as well, they're all hooked together and overflow into the downspout if they're full. We have a clear tube at the end so we can see how much water we have. The system is also easily expandable if we want to add more barrels, we think we can fit 7-10 more across the back of the garage.
One of the best things about this system is the cost. We only spent about $120 for the entire system (including deck). The deck was built with lumber we removed from the deck on our house, we wanted a smaller sized deck on the house. The barrels are food grade plastic barrels and cost us only $10 each (you want to make sure you don't get barrels that had chemicals in them). We spent about $50 on other materials, posts, PVC (we also had some of that sitting around that we used up).

Plinth Telephone System on the Fourth Plinth (One and Other) performance art in Trafalgar Square, London.
This plinther ran lengths of string with polystyrene cups at each end from the plinth to the audience in the square.
Obviously doesn't know much about the science of sound. You need two tin cans tied to a length of string and no obstruction bewteen them. The string was wound around the pole and through the net. Schoolkid error. Then the string became a trip hazard, so a work experience trainee from the One and Other team was delegated to gather it.
Then she played guitar which we couldn't hear.
