I've been asked about my seed-drying racks. For anyone interested, here's how I make them:
Starting with 1 x 3 lumber, I cut two pieces 12 inches long, and two 18 inches. Then I set my rip fence to the width of the wood, and cut a strip off each piece. These will be 3/4" square. Large holes are bored in the main pieces, to providing ventilation from underneath.
The main pieces are glued and nailed to form a rectangle, and a piece of window screen is stapled in place. The 3/4" square pieces are then glued and nailed on top of the screen.
This top-frame serves several purposes. First, it seals the wire of the screening, so there is no danger of pricks and cuts from exposed wire. And it serves as a retaining fence for the seeds.
In use, seeds are spread in a single layer on the wire, and the rack put on a shelf in my drying room. Their shape is such that they are stackable (and the large holes provide ventilation). I've stacked them five high with no problems---a great space saver. Don't forget to label each rack as to the type of seed and the date you put them up to dry.
