Most of us gained a familiarity with siege weapons from Age of Empires, and the march of technology has meant these relics aren’t typically seen on modern battlefields. However, development continues apace in the enthusiast community, and [Tom Stanton]’s latest trebuchet design puts a different spin on launching projectiles at speed.
The design takes advantage of the flywheel as an energy storage device. The flywheel is spun up to speed using a hand crank, through a timing belt and a set of hybrid 3D printed and CNC aluminium gears. Once spun up to sufficient angular velocity, a trigger releases the tennis ball payload from a sling, flinging it forth at speeds over 180 miles per hour.
Moving on from classical materials such as wood and nails, [Tom]’s latest design relies on aluminium in an effort to build something that won’t rot when left outside in the rain. The use of aluminium profiles also makes adjustment and redesigns easy, while providing the necessary adjustments to dial in things like release point and belt tension. We’ve featured a few different designs over the years; the walking-arm trebuchet is perhaps the most oddball of all. Video after the break.
Unless you are only catering to English colonies. you should provide proper SI units as well…
No, it’s not as if he *should* do in his video whatever *you* deem appropriate or correct. Perhaps he *could*, but then again he already has specified values in SI units. Have you seen the video at all?
And before you call me on the tone of my reply, this old “English colonies” shite is quite tedious, frankly, and all because some speeds are given in mph. Please.
Note mention that MOST (like 95%) of the world uses metric, not just the English colonies, due to its logical ease of use. Its curious why the US cant seem to figure out how to use it…
The video itself includes metric units.
“English colonies” (by which I assume you mean British) all use metric units because that’s what mainland Britain uses. The only country that habitually uses non-SI is the US, which is an *ex*-British colony
Fantastic, excellent work!
