homemade 2.7" cannon, any value?
I guess this is the best place to put this: Many years ago I built a small blackpowder cannon, very close in size to what was once called a mountain howitzer. I make balls either from cement (1/2 lb.) or lead (3lb.) and used to shoot at old cars or vans a local junk yard would loan to me for "ventillation". The cement made a nice hole in one side then would turn to powder, the lead went thru and put big dents in my railroad tie backstop. I know these pictures stink, but my cheap camera doesn't speak english and this is the best it'll do. Unfortunately my area has been "developed' subatantially over the years and the new residents don't like booms. I'm legal and haven't been told to stop 'yet' but I'm sure it'll come. My question is: does this thing have any value, might I actually be able to sell it? I'm sure the liability issue would need be covered in writing.
