Greetings Chewy. I hope you get a chance to read this. making that brass naval cannon was a bucket list item for me and required some tricky machining to complete. Rotary table specific for the trunion straps and chain eyelets. As for your comment about it not firing, you are correct, but the barrel was intentionally left deep enough for it to be bored deeper and with an added fuse hole....BANG. But, YouTube has many policies covering home made firearms, so I decided to keep it a static model for the series to stay within the platform guidelines. Who knows what happen once the cameras stopped rolling ?
