With a highly polished back of the plane blade, the next step was to hollow grind the bevel on the tormek. While the Tormek machine is not cheap, it was pointed out that it produces repeatable accurate grinds, quickly and quietly. Have a great week, Chris

Just a comment about the above.

Step 1: flatten the back of the blade and then polish to the level you intend to use for the final bevel. (a sharp edge comprises two, equal intersecting sections ...).

Step 2: grind a hollow at the angle you wish for your final bevel. Here I used the Tormek, but another blade was also prepared on the dry grinder.

A hollow grind facilitates easy freehand honing - the bevel face will balance more easily on two "rails" than on a flat (bevel) surface (the flat surface is rarely flat and this will encourage the blade to rock and round over the face). A hollow ground at the cutting angle creates a coplanar face, enabling a microbevel that may be stropped more easily than one that is secondary to the bevel face (that is, at a different angle). Refer to: http://www.inthewoodshop.com/Woodwor...gStrategy.html

I am hoping that we have the pictures of the freehand honing process since this was an important point of the exercise. I will consult with Chris and see what we can do to create a tutorial.

My sincere thanks to Derek and Lynndy for letting us loose in your shed and house and for your tips on sharpening planes and chisels. I haven't been able to put my new found knowledge into practice yet due to other things getting in the way - things like work, chores etc.
It was really great to put some faces to the names and tap into the knowledge to be found in this forum. I am looking forward to the next one.
