No problem;i was just trying to compare it with the ones i have. I guess 30 cms. diameter (not perimeter) would be a really huge ball; mine are 19 cms. and weigh circa 8 kilos.
Sorry for your back. By coincidence, mine is also killing me; i am making arrangements for decompression surgery ! |

No worries about me; I'm 41 and it's just a minor (but persistent) ache for now, but my dad has a history of pretty bad back problems that started around this age, and I do have a bit of a hollow back, so I'm mostly just exercising caution. |

Just for one's perusal ...
Yes, a 'gross' bombard, they call it. An example of gross bombard catalogued in a local museum, dated from the end XV century, would throw a ball with 33,5 cms. weighing 85 arráteis (pounds)= circa 40 Kgs. It would need some 12 Kg. of black powder to be sent off such 1500 Kgs. rought iron tube.
