no previous part Part 1 of Routing Inlays series Part 2: MORE CELTIC INLAYS »

INTRODUCTION
.
.

When I started experimenting with using my router for inlays I thought only in the context of straight lines since that was what routers did best. Unfortunately my tastes in designs included Celtic Art especially Knot-work which is mostly curves. These would obviously need some sort of template to guide the router. A cursory inspection of a typical Celtic Knot suggests that they are too complex for a simple template. However a closer examination and study convinced me that some patterns at least had simple Motifs which are repeated several times to form an apparently intricate design.

I intend to demonstrate that the following two fairly complex traditional patterns, one Knotted piece and one Border, have underlying simple Motifs.

MATERIALS

.
.
.
I used 1cm (about 3/8” ) thick Walnut for the bases. The inlays are PVC strip 1mm thick. These are cut from PVC which is sold here in Europe for edging kitchen tables etc. I used one white, two black and again one white. Obviously the choice of materials is a matter of choice, depending on your choice of router bit diameter and inlay.

CELTIC KNOT PATTERN
.
.
.
IMG_2774

This drawing is a fairly typical Celtic Knot, although apparently very complex, if you ignore the over/under aspect you can see that the design consists of an OMEGA shaped Motif repeated twice more after being rotated 60°.
.

.

The template therefor consists solely of this motif, which is routed then rotated 60°, routed and rotated again, and yet again. Obviously great care is necessary to place the template accurately.

The routed pattern should look as above

CELTIC BORDER PATTERN

This Source is a fairly typical Celtic Border pattern, again the pattern is simpler than it appears at first glance, the motif in this case is the shape cut out in the template below.

The routed border should look like this. Again the accurate placing of the template is essential to the success of the operation . .

The inlaying is again straightforward. . .

Awesome breakdown Maclegno. Thanks for setting the stage for the steps you took in working out the process. Clever use of the two tone laminates to get the look of the entwining of the pieces. I love it when you masters of the craft display your work, but it really is a generous bonus when you folks draw it out like this.
