I did not make this cannon a member here did it for me in trade for a item I had. The mount I made for it goes lacking and I want to redo it. This is a pic of it he sent me showing the progress.
It fires golf balls not sure how far have not seen one land yet so I am looking for a longer range. Talked to another member he told me his is hitting around a mile. I look forward to see others and getting some ideals on how to design a mount.
