Boggs Concave Spokeshave
This spokeshave represents a collaboration between Lie-Nielsen
Toolworks and Kentucky’s Master Chair Maker, Brian Boggs. A 2
5/8" diameter sole makes this tool the right choice for working chair
spindles and other round parts.
Geometry:
The blade has a 25° bevel and is bedded at 40° to the
sole, bevel down.
This tool is set up to take thin shavings (maximum .008-.010" or
so). A tool with a large mouth will not perform as well on
finish cuts. If you need a heavier cut, the tool can be easily modified
by filing a chamfer on the leading edge of the mouth to allow a bigger
shaving to pass.
Blade Sharpening:
Use the spokeshave to work a 1 1/2" piece of wood to a radius that
matches the blade when the blade is held at 25º to its surface
(the angle of the bevel). Glue sandpaper or microfilm to the
wood and use to hone the blade. Make several pieces for
different grits. Use with diamond paste or honing compounds
for the best edge. Hone the back of the blade as usual.
Setting depth of cut: Set the blade by eye; sight down the sole and
look for the dark line of the projecting blade. Make
adjustments with a small hammer. The corners of the blade are
meant to be flush with the sole when the blade is set to take a
thickish shaving.
Materials:
Manganese Bronze body and cap, Brass thumbscrew. Heartwood Hickory or
optional Cocobolo handles.
The blade is A-2 Tool Steel hardened to Rockwell 60-62, cryogenically
treated and double tempered. Our heat-treating technique ensures that
the blade will take and hold a very fine edge for a long time. After
heat-treating, the blade is fully surface ground on the top, back, and
cutting edge, giving a smooth, flat surface that will take a mirror
finish very quickly.
Maintenance:
Polish the bronze parts with any good brass polish or enjoy the patina
that develops with age and use. Oil the blade to prevent rust.
Guarantee:
Materials and workmanship are guaranteed for the life of your tool.
Call for repairs or replacement parts. We are available for advice if
you ever have a problem using your tool.
Proposition 65 Notice: Bronze and brass alloys contain lead, a chemical known to the State of California to cause cancer and birth defects, or other reproductive harm. Wash hands after handling.
