What's the most dangerous weapon you think you could make, if there were no limits on physical resources and you were restricted to your own current knowledge only?
Depends on what you mean by "Most dangerous". In terms of practical projectile weapons, quite possibly a crossbow, if I put enough thought and effort into it. Less practically but still arguably dangerous... Siege weaponry; an onager, possibly a cannon, maybe even a trebuchet. I know most of the theory behind those.
I could quite easily make some basic explosives. Nothing like modern fragmentation grenades, of course.
