I have a piece of 3" Dia steel and plan on building a swivel gun. I have a friend who will drill the bore to what ever dia and depth I need.
So, how large a dia bore can I safely put in a 3" outside dia breech?
I would like 1-1/4" or 1-3/8". I dont think I dare 1-1/2"??
I will not overload it, maybe 100 gr FFG to 150 Gr FFG Max. But I cant control what anyone else might do later, so I want to keep it safe.
Surly, there is some kind of "Ratio" guide line of Bore size to wall thickness for steel?
Any help would be appreciated. I dont want to end up in the Catastophic Failure section!
Thanks in advance.
