I bought this plane simply for trimming edges to fit when I screwed up a cut. It does this fantastically...And much more than it was ever made to do.I recently found a sawmill that sells rough white oak for $2 a boardfoot. Nifty price, big pain, as I have no large hand plane or electric planer. I picked up 50 bdft in widths of around 24".
I planed all 50 feet using this little plane. Took some time (about 30 hours with tons of sweat and some very sore hands), but with the proper edge on the blade, I didn't even need to sand the wood after building. It was all done. ;)

As for construction of this plane...It's solid. I've dropped it many times onto a concrete floor with no damage at all. It's a trooper of a plane.
