Although I had never made a Krenov-style hand plane, nor a little hammer, I am pleased, as things worked out well: The plane does a nice job, taking shavings as thin as 1-2 mils thick (0.001″ to 0.002″). And this little hammer works much better when I have to make minor adjustments to the iron; all the other hammers in the shop were too big, or too heavy. I even used an old, beat-up spoke shave eons old, with chips on both mouths, but it did its job getting all edges rounded and fairly smooth.
In making the hammer (red oak, no finish, ebony wedge in the kerf), I used the procedure described in detail by David Finck in his book, Making & Mastering Hand Planes. As I mentioned in an earlier post, this is the book I used as a reference to make the hand plane, too.The brass head is solid brass, 5/8-inch diameter, 2-1/2 inches long; the handle is 11-1/2 inches long. Thanks, David, for a terrific book!
