Proper Soundboard Crack Repair
Repairing soundboard cracks the traditional way, by carving
them out with a hand shimming tool, is tedious and seldom
results in a perfect fit between shim and board. To best
restore the structural integrity of a cracked soundboard the
damaged wood should be replaced with new, joined as
perfectly as the original soundboard planks.
The router base and custom bit shown here allow you to do
just that for quality, permanent repairs. The base is made of
UHMW Polyethylene with a metal bracket and special hose
clamp to attach your power source. This can be either a
small air die grinder as shown here or the hand piece from an
electric Foredom tool. For shops equipped with compressed
air, the die grinder is the best choice. Air die grinders are
compact, run at true router speed, and are useful for many
other shop jobs.
Features of this system:
The compact design reaches very close to the rim and bridges.
The 1" x 1" x 1/8" aluminum angle metal fence (purchased
separately from your local hardware store) mounts instantly to the
soundboard using double-stick 3M© Scotch #114 Mounting Tape.
There is no need to drill holes in the soundboard or rig up
complicated clamping arrangements. The Router Base rides along
the fence like a mono-rail, guaranteeing complete control with no
danger of veering off course.
The base has both cross-wise and lengthwise fence slots; this allows
the router base to slide along the guide fence in two modes, either
parallel to the fence, or crosswise to the fence, depending upon the
location of the crack in relation to the rim and bridges.
The air tool mounting bracket adjusts fore-and-aft on the base. This
allows you to increase the width of the groove up to 7/8" to clean
up wandering or multiple cracks without relocating the guide fence.
Multiple fence slots in the router base allow routing of two exactly
parallel grooves, without moving the fence, for replacement of
panels up to 5 1/2" wide.
