I loved that article too... I have the 'found sink' and the left over wood to build our table and its all sitting in a pile since November waiting on hubby to get motivated and build it already. I even wanted to add an old scale to the table to weigh my produce before washing and cutting for the spread sheets we are keeping.
I also want a nice spot to keep a cooler so I can keep everything fresh and from wilting while I work.
I have a workbench in the garden and my husband just bought me a beautiful old double basin soapstone sink that is going to be hooked up on side of the house near the garden hose, which is right close by.
I know what you mean about having a scale to weigh your harvests, its convenient to have outside.
I have two of them, a hanging scale and a counter top scale that I got a few years ago at an antique auction.
Lets hope we have lots of stuff to weigh.
