Quoting David Roberts
An original topic for a MOC, cleverly designed and built. I like how it both looks and works like the Roman original, especially the ratchet mechanism and the twisted ropes to power it.
My suggestion to improve the range would be to add snot tiles in the slot where the ammo would go. It would make a smoother ride for the ammo causing less friction. Nice build. I would love to see it with some Romans around it or it in battle or something. ~8)
