Idk your a relatively large YouTuber but your videos still feel like I’m discovering some sort of treasure or secret knowledge ❤❤
-
Dude, your videos have been better and better everytime. Your craftsmanship and historical re creation is fantastic. When you melted the zinc.. It really made me realise how "Magic" this stuff must have felt for someone seeing it for the first time. Much love Fraser

A Solar Death Ray is something we should all aspire to in life.

Professional hand tool woodworker here, dude your woodworking skills have come such a long way in such a short time! Beautiful work riving and dressing your stock, and very impressive chisel work. You're doing amazing!
-
Never stop using the Black & Decker workmate. It's good juxtaposition
-
Yet another fascinating and elucidating video. You have more than earned your rapid growth in viewers and I hope and predict your channel will continue to grow. Thank you for the quality content.
-
I had the honor and privilege of getting dinner with this fine gentleman a spell ago - Thanks so much for your fine content. Support this work, folks!
-
I love how you provide historical context, especially on those messy years where science wasn´t still consolidated
-
Nice surprise woodworking episode
-
Yes! New alchemy stuff to geek out over!
-
Your works inspire me to make my own reconstructions of ancient instruments and curiosities. I'm especially interested in astrolabes and astronomical instruments. Thank you!
-
I made a one of these using a big fresnel lens out of an old rear projection TV. It's could liquify the brass of a padlock and turn most rocks into lava. Sunlight has SO much energy in it! Great video.
-
Ooh I'm not usually this early to any video. Perfect timing!
-
The woodworking combined with historical narration was ASMR. Loved your description of observations, reminded me of the old texts.
-
finally new Fraser Builds !!
-
2:04 By the way, the s in "Fresnel " is sort of silent (technically it modifies the pronunciation of the "e" slightly). There was a period of time when old french had a lot of es's in it, but they all got swapped out with "é" except it would seem in some names where the spelling didn't change but the pronunciation did.
-
That stain (and the woodwork it is on) is gorgeous. What a beautiful color!
-
Your skills have leveled up! This is easily the prettiest device you have made so far. This video rules!
-

It is funny to think that this object dates way earlier than 15th century and was used for completely different reasons. I’m from Siracusa in Sicily, where Archimede was born. In my school there is a big statue of Archimede standing next to a huge piece of round glass (like the one you created). From a young age we were told many legends on Archimede. According to one of them, it was said that Archimede used the lens -and also some giants mirrors-to burn the enemy ships.
