Please message us after each purchase to let us know what two radius insert
sets you would like with your jig.
For luthiers who prioritize precision and adaptability, we offer the
Fretboard Radius Router Jig. Utilizing 3D printing technology, this tool
provides accurate and consistent fretboard radiusing.
This jig will work with fretboards up to 3 inches wide.
We recommend a long straight bit with a 3/8" cutting diameter such as the
Whiteside 1023.
Our jig is tailored to fit popular compact router models such as the
Milwaukee M18 Fuel, Ryobi P601 One+, Dewalt DWP611, Bosch PR20EVS, Makita
RT0701C, and Ridgid R2401. If your router isn't listed, we encourage you to
contact us for potential custom base solutions.
The jig comes with the option to select two sets of radius inserts, covering
a spectrum of fretboard designs. Should you not find the radius you're looking
for, we offer custom radius inserts upon request to meet specific requirements.
Inside the package, you'll discover the Fretboard Radius Router Jig body,
router base, and your chosen radius inserts.
Designed with dedication to the craft of lutherie, this tool aims to deliver
both reliability and precision. If you have queries or need additional
information, we're here to assist.
Instructions:
1.Setting the Height: Choose the thickness of your preferred board material
MDF, plywood, or hardwood) such that, when placed on your working surface,
there's a 1.5-inch height from the top of the surface to the top of the
fretboard. Importance of 1.5-inch Height: The radius inserts are designed to
compensate for the distance from where the router base contacts the radius
insert to the top of the fretboard. This height ensures an accurate radius
replication. If the setup has a height less than 1.5 inches, there's a risk
that the resulting radius on the fretboard may be rounder than intended.
2. Board Preparation: Cut the chosen board material to a width of 4.5
inches. Ensure the edges are straight and the board is free from defects.
Securing the Materials:
3. Use double-sided tape to affix the board to your workbench securely.
4. Positioning the Fretboard: Center the fretboard onto the affixed board,
ensuring even spacing on all sides. Once positioned correctly, use double-sided
tape to secure the fretboard in place. Note: Carefully inspect the fretboard
to verify there are no raised sections or uneven areas that might interfere
with the routing process.
5. Attaching the Jig: Attach the jig to the router base using the provided
screws, ensuring a firm and secure fit.
6. Installing Radius Inserts: Slide the desired radius inserts into the slot
located in the jig's body. Once properly positioned, tighten the set screws to
secure the inserts in place.
7. Placing the Jig Body: Position the Fretboard Radius Router Jig body onto
the setup constructed in steps 1-4.
8. Positioning the Router: Place the router base onto the jig body, ensuring
it aligns correctly and sits stably. Make sure all four bearings on the router
base are making contact with the radius insert for accurate routing.
9. Centering the Router: Align the router using the center lines provided on
both the router base and the radius insert.
10. Adjusting the Router Bit: Carefully lower the router bit until it barely
touches the fretboard. We advise against using a spiral bit for this process.
Opt for a straight bit for the best results.
11. Starting the Routing Process: Slide the jig in a manner that the router
bit is clear of any wood. With the bit in a clear position, safely turn the
router on, readying it for the routing process.
12. Routing the Fretboard: Begin routing the fretboard. Ensure the router
base bearings maintain contact with the radius insert at all times. Move with
the grain of the wood. After completing each pass, slide the router base
laterally to start a new path, ensuring full coverage of the fretboard surface.
