Engineering learner Reuben heading for ‘pole position’

Published

on

ENGINEERING learner Reuben Whitehead has been turning heads with his mechanical talents when he recently designed and built his very own battery powered go-kart.

Reuben, who is a passionate Formula One fan, works part-time at West Wales Karting and decided to rebuild the kart earlier this year after they kindly donated a pre-existing kart to him.

The process involved stripping the kart down to a bare chassis and then refurbishing it. This was followed by implementing the electrical aspect of the kart and fabricating mounts for both the batteries and motor made from carbon fibre and steel.

The key components and materials used were steel for the chassis, aluminium for the rims, and an inclusion of carbon fibre for both the motor mounts and battery.

The motor produces 2.5hp and has an efficiency rate of 90% when in operation. The torque produced is 8.4-foot pounds when in operation and the motor revs 1500RPM.

Reuben explained the purpose of his project, “I built the Go-Kart because I am passionate about motorsport and enjoy karting both in local competitions and with friends so for me the opportunity to build an electric kart was exciting and something that would require me to use my skills that I have developed throughout my time at the College. I also built the project as I knew it was something that I would enjoy undertaking and be able to learn new skills along the way. Being able to get hands on with a kart and understand both the fundamentals and intricate aspects was important for my development as an aspiring motorsport engineer, hopefully one day with Formula One.”

Reuben took his first test drive in the car earlier this month using the track based up at West Wales Karting.

Reuben also discussed what inspires him to achieve his dream career.

Reuben explained, “The individuals who inspire me are my mum, for how brave and courageous she is, for always believing in me and supporting me. My late stepdad, he never gave up even at the toughest of times and always kept fighting even when the odds were against him as well as teaching me that if you work hard enough anything is achievable. Finally, Lewis Hamilton for showing that again with hard work you can achieve anything and that no dream/goal is too big, also the way in which he conducts himself after tough losses on the racetrack.”

An articulate learner, Reuben spends a large amount of time in the machine workshop whilst studying at the College where he has developed skills in working with lathes and milling machines, hand fitting tool techniques as well as CAD and precision measurement practices which has aided his knowledge into the world of car design and engineering.  

Aside from Reuben’s College studies, he has self-taught himself many transferable skills.

Reuben said, “I can’t take all the credit, having been fortunate enough to have experience of refurbishing classic cars with my stepdad growing up, as well as being able to build rally cars when on work experience whilst studying in my first year of College, this has certainly helped me learn and build a skillset that can be applied in numerous engineering environments. Spending time in the workshop and learning from tutors who have real industry experience has helped me.”

Curriculum Area Manager for Engineering Will Bateman, expressed how proud the department is of Reuben, “Reuben has worked at a consistently excellent standard throughout the two-year programme. We are incredibly proud of his final project, that has showcased his skills and learning from the course. Reuben is a true engineering ambassador having spoken to numerous 14–16-year-old groups on choices post-compulsory education.”

Reuben plans on becoming a Motorsport Engineer in Formula One after his studies and this project has fuelled his motivation to show potential employers just how talented he is.

Stonehenge may have been built to unify the people of ancient Britain

Published

on

THE RECENT discovery that one of Stonehenge’s stones originated in Scotland supports a theory that the stone circle was built as a monument to unite Britain’s early farmers nearly 5,000 years ago, according to a new study by researchers at UCL and Aberystwyth University.

In a research article published in the journal Archaeology International, academics analyse the significance of the recent discovery of the Scottish origin of the six-tonne Altar Stone, which confirmed that all of the stones that make up Stonehenge were brought to Salisbury Plain from many miles away. 

In their new paper, the researchers say that Stonehenge’s long-distance links add weight to the theory that the Neolithic monument may have had some unifying purpose in ancient Britain.

Lead author Professor Mike Parker Pearson from the UCL Institute of Archaeology said: “The fact that all of its stones originated from distant regions, making it unique among over 900 stone circles in Britain, suggests that the stone circle may have had a political as well as a religious purpose – as a monument of unification for the peoples of Britain, celebrating their eternal links with their ancestors and the cosmos.”

Co-author Professor Richard Bevins of Aberystwyth University, said: “It’s really gratifying that our geological investigations can contribute to the archaeological research and the unfolding story as our knowledge has been improving so dramatically in just the last few years.

“Our research is like forensic science. We are a small team of earth scientists, each bringing their own area of expertise; it is this combination of skills that has allowed us to identify the sources of the bluestones, and now the Altar Stone.”

The study has been published (on 20 December) the day before the winter solstice, when the setting sun dips below the horizon over the middle of the Altar Stone and between the two largest upright stones (one of which is now fallen).  During this winter period, Neolithic people feasted close to Stonehenge at the great village of Durrington Walls, and the midwinter solstice was probably central to these events.

Stonehenge is famous for these solar alignments on the solstice and even today attracts large crowds to the site on the shortest and longest days of the year. In addition, it was also the largest burial ground of its age. Some archaeologists think it might have been a religious temple, an ancient observatory and a solar calendar, and this new research adds a political dimension.

Professor Parker Pearson, a Professor of British Later Prehistory, added: “We’ve known for a while that people came from many different parts of Britain with their pigs and cattle to feast at Durrington Walls, and nearly half the people buried at Stonehenge had lived somewhere other than Salisbury Plain.

“The similarities in architecture and material culture between the Stonehenge area and northern Scotland now make more sense.  It’s helped to solve the puzzle of why these distant places had more in common than we might have once thought.” 

Stonehenge’s 43 ‘bluestones’ were brought from the Preseli Hills in west Wales some 140 miles away, while the larger ‘Sarsen’ stones were hauled from their sources at least 15 miles away to the north and east of the stone circle.

Transporting these massive monoliths was an extraordinary feat. Although the wheel had been invented, it had not yet reached Britain so moving these massive stones must have required the efforts of hundreds if not thousands of people.

The researchers point to how Stonehenge’s horizontal Altar Stone is similar in size and placement to the large, horizontal stones of the stone circles of northeast Scotland, where the Altar Stone originated.

These ‘recumbent stone circles’ are found only in that part of Scotland and not in the rest of Britain, so there may have been close ties between the two regions. Megalithic stones had ancestral significance, binding people to place and origins. The Altar Stone may have been brought as a gift from the people of northern Scotland to represent some form of alliance or collaboration.

It is difficult to pin down a precise date when the Scottish Altar Stone was brought to Stonehenge, but it probably arrived around 2500 BCE around the time that Stonehenge was remodelled from its original form.

This is the timeframe when the Neolithic builders erected the large sarsen stones forming an outer circle and the inner horseshoe of trilithons – paired upright stones connected by horizontal ‘lintels’ – that is present today. The Altar Stone lies at the foot of the largest trilithon, which frames the midwinter solstice sunset to the southwest. This was the second stage of construction at Stonehenge, long after the first stage (around 3000 BCE) when it is thought the bluestones from Wales were erected.

This second iteration of Stonehenge was built at a time of increasing contact between the people of Britain and arrivals from Europe, mainly from what are today the Netherlands and Germany. The researchers suggest that this period of contact may have been what spurred this second-stage rebuilding, and the monument was a reaction to these newcomers meant to unite indigenous Britons.

The new arrivals brought with them knowledge of metalworking and the wheel and, over the next four hundred years, their descendants – known as the Beaker people on account of the distinctive pots they buried with their dead – gradually replaced the population of indigenous Britons, and people with this European ancestry became the dominant population across the island.

The geological research was supported by the Leverhulme Trust.

Tutor banned after Pembrokeshire College drug incident

Published

on

A PEMBROKESHIRE COLLEGE tutor has been struck off after admitting to police that he had cocaine on college premises but later denying the offence to authorities.

The Fitness to Practise Committee of the Education Workforce Council (EWC) found Phillip Lewis, a former tutor at Pembrokeshire College, guilty of unacceptable professional conduct. The committee said Lewis provided inconsistent explanations about how he came into possession of the Class A drug.

Lewis accepted a police caution in January 2023, which is considered a full admission of the offence. Despite this, he later challenged the allegations, raising concerns about the police’s handling of the matter.

Maxine Thomas, the safeguarding lead at Pembrokeshire College, told the committee that CCTV footage from November 23, 2022, captured a packet of cocaine left on a counter shortly after Mr Lewis had been in the area. The footage also showed Lewis retracing his steps as if searching for something.

The committee reported that Lewis gave conflicting accounts of the incident, including differing accounts of where and when he claimed to have found the packet. His explanations did not match the evidence from the CCTV footage.

“He provided inconsistent details about the circumstances in which he came to possess the packet, none of which aligned with the CCTV evidence,” the committee’s report stated.

Lewis claimed he had discovered the packet in a corridor but lost it shortly afterward. The panel, however, concluded that he should have reported the find immediately if his account were truthful.

“The committee concluded that Mr Lewis brought the packet onto college premises himself and did not hand it in because of its illegal nature,” the panel’s findings read.

The panel deemed that possessing cocaine on college grounds and accepting a police caution constituted unacceptable professional conduct. While no direct harm to students was noted, the panel highlighted the significant risk posed by such actions during working hours.

In deciding to remove Lewis from the professional register, the committee acknowledged his prior good record and his participation in the EWC process. However, these factors were outweighed by aggravating considerations, including his attempts to cover up the incident, providing contradictory accounts, and failing to demonstrate insight or remorse.

Lewis will be eligible to apply for re-registration in two years.

World of engineering and welding SPARCs interest in Ysgol Harri Tudur’s female learners

Published

on

AN EVENT hosted by Ledwood Engineering gave girls from Year 8 and 9 at Ysgol Harri Tudur first-hand experience of the world of engineering recently. 

Engineering is a booming sector in Pembrokeshire with a high demand for skilled workers in exciting career pathways associated with the development of low carbon and renewable energy industry and the Celtic Freeport. 

The young women heard from industry experts on the importance of engineering in Pembrokeshire, and had hands on experience using a welding simulator, at the company’s Pembroke Dock site. 

The learners are part of the County’s SPARC (Sustainable Power and Renewable Construction) initiative aimed as inspiring and empowering young females to consider careers in science, technology, engineering and mathematics (STEM) pathways where females are under-represented in the workforce. 

SPARC is funded through an alliance comprising Blue Gem Wind, Ledwood Engineering, Port of Milford Haven, RWE Renewables, Pembrokeshire County Council, Pembrokeshire College and the Swansea Bay City Deal. 

Mrs Laura Buckingham, SPARC practitioner at Ysgol Harri Tudur said: “Our learners had a fantastic experience at Ledwood Engineering.  They were given lots of advice by industry experts on the different career options and pathways within the engineering sector.  

“They appreciated the opportunity to ask their questions and found the session very informative. Having the chance to trial their welding skills on the simulator was an experience they continue to talk about and has definitely piqued their interest.”

Poppy Sawyer, Year 8 SPARC learner added:  ‘It was a really good trip. Talking to the different people there has helped me know more about the jobs we could get which will be very useful when making choices for my future.”  

 “They helped us a lot by giving us lots of information. We were able to look around and try welding. It was really fun,” added Tianna Marshall, Year 8 SPARC learner.

The Regional Learning and Skills Partnership also launched its Explore Engineering interactive website at the event.
