OK here it is, I just drilled some boysen ports in a test cylinder and would like some feed back from everyone. Keep in mind I don't have a way to build up the weld on the outside so I don't want to run the risk of blowing thru the outside wall. Any tips will be considered and appreciated. Thanks in advance.
