Thanks all. Now that yo mention it, I think I have a level app in my iPod.
I understand that 30* is just guidelines but I didn't want to start at 40* and not realize it.
Thanks again to all!
Hopefully I'll get to hang Friday night.
Thanks, everyone. This is a particularly helpful thread. I had cut an old credit card on a 30* angle and had used that, but this is just so much easier. I checked using a protractor and my "gun" is just about exactly 30*.
[Now I guess I'll be reading jokes about my "gun" ]
Even Cowgirls Get the Blues' (1993).
It may not be rocket science, but it's still science.
