I decided to abandon the firewood plane blank after I realized it was lodgepole pine. I’m playing it safe by using a Maple turning blank. It was about 2×2x20. I cut it down to two 10” segments and glued them together to make a 2×4x10 blank. It will be a little wider than necessary, but I’ll have plenty of room for error when I rip the sides.
It also turned out the blade on my thrift-store #5 is more pitted than I had hoped. I sharpened it as best I could and managed to get a passable surface for the glue up, though the joint probably won’t be invisible.
