I decided to make a wooden router plane the other day. After searching a number of different sites I came across an article by John Wilson. As it so happens I took a Shaker Box making class with him years ago.
Using ba 7/16' Allen Key as the blade and some 1 1/2" cherry for the body it was a very pleasant undertaking. Just finished sanded a while ago and applied a coat of BLO.
Will post a pic tomorrow.
