Weird question. Do you reckon using available materials and tools of the mid 19th century you could build/shape a board capable of knifing into a pipe bomb? I’m thinking it would be a wooden hull big gun similar shape to modern big guns but obviously allot heavier due to the wood/glues/resin required. Three wooden fins jammed in somehow. Or even a solid board carved out of a single block of balsa. Surfed by someone like Mason or JOB. Possible or just too heavy/unresponsive?
