Brass Infill Shoulder Plane a quick look by Jim Hendricks

In recent posts we discussed rabbet and shoulder planes and I was asked to discuss the geometry.

 

 

So today I took it apart, sharpened the KT Tools O1 steel iron and tested it on a scrap of hardwood.

I have also tried to explain the difference between "grinding", "honing" and what I call "polishing to death!"

I decided to show that straight from a coarse stone or plate you can get a razor sharp edge as long as you get two flat edges meeting together at the desired angle at an infinitely small point.

This is about all I was allowed to do in the workshop today but I hope this clears up a few questions.

Pat Meeuwissen asked what was the bed angle? The answer it is exactly 17 degrees sir!

The wedge is 13 degrees so the throat pocket is 30 degrees.

Another question was about sharpening. I stated that "sharp" did not come from "polished to oblivion". So in this test I will try to show this by ONLY grinding to "coarse" using a DMT DiaSharp. This is the face. FLAT to the edge is vital!

I then ground a new bevel at about 25 degrees. Again only to a "coarse" but again - FLAT and to the very edge and beyond, forming a wire burr which I snapped off on my palm.
