As I left off, the fence, lever cap, and body were all not finished. the body is just a three piece lamination. During the glue-up, try to keep the skates flat with each other, though it is good to also lap them after the glue has dried. For the lever cap, I cut a notch less than halfway across a piece of aluminum 1/4" thick and about 3/4" wide. I then drilled and tapped a hole at the end without the notch. For the retaining bar, I used scrap 1/4" diameter steel bar. For the fence I glued two pieces of wood at 90 degrees and then another larger piece onto the "L". For the fence adjustment system, I sawed and chiseled a dado that was just a little undersized for the arm. I then took out a little material from the upper half of the groove. That way I could put the arm in the desired position and press it down in the groove for a tight fit. Then after everything is dry, assemble the plane and set the blade for a light cut, and take it away.
Make sure the blade is tapered so that it's bottom is slightly wider than the top.
Make sure the skate is totally flat.
Make sure the blade is sharp.
Make sure the blade is not set too deeply or too far in.
