Quick test of a tiny QEV cannon firing air at 12atm, viewed through a Schlieren setup (no razor blade). Unedited at normal speed. I didn't quite understood the need for a razor blade but without one I still see the flow of air. For me, the razor blade just makes the dot of light smaller(?) If anyone can clarify me what the razor blade really does and where it should be placed (in the source of light or in the camera) I'd really appreciate. Also important to note that this is AWESOME to look with the naked eye but almost the dimmest light can blind you. I covered a tiny LED torch with aluminum foil and punctured a hole with a sewing needle, on the side! so that the LED doesn't bright directly through the hole. Take care with the eyes!!

It would be wonderful to win, so please cast your vote here: https://awards.classicboat.co.uk/restoration-of-the-year-under-40ft/ Our friends over at Berthon Boat Company have been nominated for the Classic Boat Awards, in the category ‘Restored sailing vessel under 40ft' for the extensive restoration of Brynhilde, a 1958 Fred Parker 10-metre wooden Bermudian sloop. https://www.youtube.com/c/BerthonBoats This is a testament to the extensive refit, expertly performed by Berthon’s highly skilled team. Well done to all who were involved in returning this beautiful classic sailing yacht to its former glory. The following series captures the extensive restoration of Brynhilde, a 1958 Fred Parker 10-metre wooden Bermudian sloop, who arrived here at Berthon on the 4th October 2019. She has been in her present family’s ownership for the past 40 years, competing in the Hill Robinson sponsored regattas in the south of France for over a decade, and most recently sailed at the 2021 Monaco Classic Week – La Belle Classe. Arriving for a deck replacement but undergoing broad further works, Brynhilde is a beautiful example of a timeless yacht refitted to an incredibly high standard. Traditional skills were used throughout this project. A talented team of Shipwrights, Engineers, Electricians, Riggers and Painters led by Dave Bolwell, more fondly known as Curly, dedicated thousands of hours to the careful refurbishment of a well-loved family yacht. - Restoration Playlist https://youtube.com/playlist?list=PLebSOrLsZM0Rr8Ca3NsnONk6tSqyUxQHt - Project Overview https://youtu.be/PKEd8WPQMj8 PART 1 - Arrival & Inspection https://youtu.be/zuZ-W80fBIk PART 2 - Exterior Restoration https://youtu.be/tw2LO662mB4 PART 3 - New Deck https://youtu.be/hh1IVTRsHDg PART 4 - Interior Restoration https://youtu.be/iiB8_5Q-X_w PART 5 - Paint and Finishing Touches https://youtu.be/g6pXaG6g43k PART 6 - Launch & Stepping her mast https://youtu.be/4eNyqHMY8ds PART 7 - Sea Trials https://youtu.be/Xod0o1YF7vU - Deck Teaser https://youtu.be/heYt0sNAkxg Paint Teaser https://youtu.be/qE12_zIOiE0 Launch Teaser https://youtu.be/tVSXG7igTIU Mast Stepping Teaser https://youtu.be/VmaCrYZ5nkE Sea Trials Teaser https://youtu.be/Ic7Qlh_cRn4 #YachtRestoration #YachtRefit #ClassicYacht #WoodenYacht #BoatRestoration #MarineEngineering #TeakDeck #YachtPaint #Woodwork #ClassicBoat #BoatBuilding #Shipwright #Lymington #Sailing #Berthon
