keg washer designs

[panadero]

Hello, I am going to build a kegwasher. Currently using the design posted here by beermaker(?), and for the amount we have it works fine. I am getting some older bunged kegs, though, and I need to be able to wash these as well. I have seen the basic washers, and just wondered if anyone had plans for one you may have built, and are willing to share. Oh, and is there a way to remove bungs from inside the kegs(ha!)?

Thanks for the tips in advance,
David
