Black powder cannon

Thinking of lathing one up. Does anyone have any plans for one made of 4140?
Unfortunately I got rid of the big lathe, the small lathe has a 1.2M bed which I guess I could bore a barrel 800mm long.
Any ideas?

Cheers

Research the type of cannon you want to build and learn from these guys how they operate.

Building the cannon is the easy part theres plenty of people here who will correctly advise you on whats required.
