The blade is a 1- 5/8 'Ron Hock' that actually measures 1.593" so the body of the plane is about 8 thousandths narrower. I used brass for the body - kind of soft but will not chip and break as easily as cast iron... The rest of the parts are 304 stainless steel. I made this one for a friend to finish up himself but will probably make one for myself.
These planes are extremely handy but also extremely dangerous since that razor sharp blade is right out there totally exposed. I have nicks on my hands from working on it - not even with it. They're perfect for trimming dovetails, laminates, plugs and similar right up into a corner.
I have the programs for the body if anyone is interested in making one. There are three programs: roughing -1/4 flat EM, a finish - 1/4 ball. then a fine finish - 1/4 ball. Probably the rough and fine finish would be good depending on how much time one is willing to devote to making the plane - .005 steps...Set the pre-sized stock in the vice by the bottom .125 or so, set to the left end topside and let her go....
