I'm not familiar with the term "edge flying", but basically what I am doing is taking boards of various thickness...White Oak, Pecan, Walnut and Maple and cutting them into strips 1 and 1/2 inches wide and about 16 inches long, turning them up on edge and gluing them together until I have a blank about 12 inches wide. I run them through the planer, cut the ends off, round off the corners, round over the top edge, rout a grove in the bottom edge of each end as a finger hold, and sand the heck out of them. I wet them down to raise the grain and sand; do this a couple of times and rub them down good with organic coconut oil.
I use Tightbond waterproof and non toxic glue. They actually look pretty good...finished them up this afternoon. I made one for a friend a few months back, and while I was setting up, I made a couple more, and they went over really well, so I thought what the heck, let's see if I can sell some. Lotta work, though, so If I can't get $30 or $40 bucks for them, I'll give them away as Christmas presents.
