The other half of our tool is a disk sander, and you can
easily attach this implement on the flywheel of your
recycled "one lunger". To do so, lay the rotating
counterweight flat on your work surface, then take the 3/4"
X 8" circular plywood blank, center it over the flywheel,
and drill three evenly spaced 1/4" holes through both
components. Now countersink the bores slightly with a 1/2"
bit, and cut a 1 "-diameter hole through the center of the
wooden circle.
Next, secure the disk to the flywheel with three 1/4" X
1-1/2" bolts, and reinstall the counterweight on the
crankshaft. The sandpaper can then be glued to a metal
plate, which is-in turn-fastened to the plywood by means of
three countersunk No. 6 X 1/2" flathead wood screws placed
near the outer border of the metal circle. (You might also
take this opportunity to wrap some duct tape around the
flywheel to cover any sharp edges.)
At this point, mount the engine block on its 3/4" X 10" X
20" wooden base. Of course, since it's best if both the
drive pulley and the sander extend beyond the platform
slightlyso the stand won't inter fere with the belt or with
your ability to smooth an oddly shaped piece of workyou
might want to trim down the foundation's width accordingly.
In any case, position the mechanism on the board, drill
four 5/16" mounting holes in line with those already in the
block's base, and install four 5/16" X 2" bolts to hold the
engine in place.
With this accomplished, you can knock together a little
sanding platform. Take your 3/4" X 3-1/4" X 13" board and
remove a 1 " X 8-1/2" notch from the center of one of its
sides. Then cut out a 3/16" X 3/4" X 3-1/4" groove-centered
2 inches from each endfrom one "face" of the board . . .
place one of your 3/4" X 3-1/4" X 5-3/4" support pieces
against one end of the sanding platform . . . and, with the
miniature table held perpendicularly against the sanding
wheel, scribe a line to indicate the angle to which you'll
need to cut the support. Duplicate this angle at a spot
4-1/2 inches below the initial line, then mark a
perpendicular from a point 1-1/4" behind the leading edge
of the support to its base. Make your cuts on these lines,
then trace the pattern on the second piece of wood and make
similar cuts.
