Nice work! Looks Great!
Here is a recent story that came to mind after reading your post.
I did an 8X10 winter scene fret piece (from Steve Good) during Christmas using BB and as I got into the last third, the saw started getting hard to control. Up till then, I had never had a board bow while cutting before. (yeah, I am still trying a lot of stuff for the first time Lol). I ended up using the "foot" to help hold down the bow. The piece turned out fine but I ruined it by staining the backer with the wrong shade of stain.
