Nice looking build!
Somewhere in this tomb of UDS builds are a few more examples I copied from. I just sandwiched a "slider", with a tab I bent on vise, between the actual drum and a larger piece of sheet metal. Used some washers as spacers and guides for the slider. It's tight, but I wanted it that way. I tap it with a machete to open and close.
Make it nice and long and be sure to space your holes a bit more than their diameter apart. That's about it. Not too much trouble, but more work than a ball valve.
