Beautiful picture, TW!
I purchased a plastic tool box in which to carry all my accessories, and learned it doubled as a loading stand for my OA. Open the lid, lift out the tray, stand the revolver in the bottom, and load away. It could fall to one side, but it's never been a problem for me.
I've seen a lot of variations, and I think you're only limited by your immagination and skill. (side note- I'm in the process of building one for a kentucky pistol and I'm on my 3rd prototype- still not as nice as TW's!)
Good luck,
Doug
