Very underrated man id love to help make this video into the mainstream if you want
Thanks man and thanks for your previous support! Do whatever you feel like doing. It would be cool to help this video but for the next year I will have a lot of work so I doubt I will be able to make videos with similar effort as the last 3

ballistas and ancient artillery are so awesome 👏
Bravo! A most excellent and comprehensive video on the subject. Very nice working model. Thank You.💯💥
I love torsion powered things
very interesting
superb stuff
Awesome! Nice Video! Thanks for the education! I subscribed!
I too am a student of Nick Watts.I agree with the approach of pre-winding the torsion bundles and having spares on hand. Wedges were used extensively in ancient times to quarry and cut stone. Many ancient soldiers spent time building with stone. Their stonework endures to this day and the use of feather and wedge sets to split stone and Lewis pins to lift stone were all a part of their masonry knowledge. I also found that I didn't need to use pins to hold the fine tuning of the washers, but steel on steel works that way. If they were dissimilar metals like bronze on steel it would be different. Think of locomotive wheels on steel rails providing traction vs. steel axles and bronze bushings acting as a simple bearing. I built an in-swinger and used modern nuts and bolts (helical wedges) to tension the bundles thinking a torque wrench would perhaps simplify balancing the two sides. Your model works extremely well, quick and smooth, very impressive. I really enjoy the explanation and exploration of the Springald 'exoskeleton' ballista. That is an idea that could taken further and would benefit by some strategic triangulation to minimize skewing. I hope you continue to work in this avenue, you have a knack for it. One thing I noticed, most people have found that in modern fibers, nylon holds a stretch, 'gets tired' whereas polyester is a better fiber for torsion applications. 🦂🛠
Very cool!
This is great stuff. Have you considered trying out the small stone-throwing variety?
generally no. if it can shoot a stone far it can shoot an arrow further. if you mean an onager then thats a whole different set of problems
cooool!!!))))))

deadly primitive wepon 💀💀💀
More modern than you'd think
What is the 19th century militaries actually had to face the if they have to face the Roman empire or 49 African nations and civilizations that they were thought were inferior to them. This alliance is so interesting either that these people don't think they're supposed to slaves are inferior to the the white man in fact their weapons and tactics was used in simple slings and arrows were so effective and defeated us with the most modern rifles and even Canon that we were frustrated every time we try to was so great and the fact that you spy so effectively against us they could tell our positions where we are in fact we thought we had spies that could find find us or used we can trust turns out we can't we can never conquer this region of let's leave it alone
