Exactly, I figured this out by now. I think I'll have much better luck with the rest of the joints. I did get good penetration into the shell of the BB but it's just not the prettiest from the outside.
Thanks for all the constructive criticism from everyone, rather than bashing. I appreciate the help and will try to apply all the suggestions here!
