Here is another idea of mechanism : https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=768498651

It's a lot simpler than what you want to build. It cannot move nor be reloaded.

thanks for the idea, I will look into it

Okay, I've remapped it so that I can use your treb while you update it. It works pretty well (I picked up a ballast after stabilizing the whole thing with the grabbers and shot it no pb) but it is so heavy... You should try to work with ballasts and braces instead of wood.
I've also made a trebuchet so that you can have a look at what I mean : https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=599572756

I will get working on it right away :) expect an updated version + description by tomorrow

Hi there, just passing by.
You seem pretty dedicated and I would like to see where this is going. Could you please indicate the keys and make sure that keypadless people (like me haha) can use it ?
