"IA Binding Router attachment"© Instructions

NEW DESIGN NOW AVAILABLE -- INCLUDES QUICK CHANGE CONTOURED FOOT
TO PROVIDE THE MOST USER FRIENDLY HAND HELD ROUTING

We are pleased to offer our recently re-designed “IA Binding Router”©. Attachment" the
package includes our exclusive infinitely adjustable guide and carbide bit. This space
saving device is designed to provide an alternative to our bench top system for those
who already own a trim router. It incorporates many of the user-friendly features
including the captured bit vertical guide. The NEW STYLE base is a Taylor factory
work alike, it rests on the perimeter of the guitar and will accurately follow the top and
back contours. There are four quick change extensions to match the contour of
your guitar. A 15' radius is pre-contoured, the others can be left flat or sanded
to suite your needs.

ASSEMBLY IS EASY

Remove the wing nuts, washers and the sliding
guide from the “IABR” base. Install the
provided cutter into the collect of your router
--- usually it will bottom out in the spindle.
Place the “IABR” base over the spiral bit. One
side of the router base will be more open then
the other to provide clearance to tighten the
collect. The “IABR” should be attached to the
open side of the router base.

The “IABR” base should be squared up
with the router base if it is rectangular. If it
is round use the router base mounting
screws as an alignment guide. The
binding attachment does not have to be
absolutely square, just make sure bit
turns freely in the “IABR” hole. Clamp in
place than drill two holes through the
“IABR” base and the router base.
Complete the assembly with the screws,
washers and nuts provide. Re-install the
guide and secure with washers and wing
nuts.

To adjust the depth of the binding/
purfling cut simply hold a piece of the
binding on the guide, match the
outside edge of the spiral bit to the
thickness of the binding then tighten
the two wing nuts. When routing a top I
recommend doing the purfling cut first.
Tape or glue a piece of purfling to the
binding then adjust the guide the same
as described above.

Adjust the height of the cut by
loosening the router base and
matching the bit exposure with the
height of the binding or purfling.
Tighten the base. Make some sample
cuts in scrap material to check your
adjustments.

Using the “IABR” is very straightforward. With this device the two problems
encountered with a stock routers are eliminated. The base of the “IABR” rides on the
very outside edge of the guitar top or bottom thus averaging the cuts along the
contours neutralizing the change in cutter angle caused by the back or top radius.
The extra long perpendicular guide allows the tool to glide along the rim at the proper
angle.

Make some dry runs around the guitar with the cutter bit retracted to determine if the
foot has the proper contour. The foot can be customized by adding a gentle and also
rounding off the outer edges of the foot.

As with any operation requiring the use of a hand held router --- the work
piece must be positively secured to the worktable. We use either our Multi-Style
mold or single purpose post mold to accomplish this stabilization. The “IABR” is very
forgiving but a moving target will cause problems. We make three light passes to
complete the channels. When making the cuts think in terms of keeping both outside
edges of the guide up against the sides of the rim --- in other words the base of the tool
will be perpendicular to the cord of the various curves of the guitar. After the first few
cuts this is automatic and will become second nature
