When I originally started out on this project, I knew a circle jig was going to be a major component of the work I had planned. I have always depended very heavily on my MicroFence to do a lot of the inlay work on my pieces. After looking at the circle jig kit on the MicroFence website and armed with the knowledge of the quality of their equipment, I pulled the trigger and received my new circle jig several days later. Set up and configuration of the jig was very easy and straightforward, and I got to work immediately.
The Demilune table I was preparing to build had several features in it that need to be cut with the jig. First was the lower band of molding that would go under the curved rail. This was segmented tiger maple, and was done this way to maintain the look of the design with the top.
With the circle jig and the segmented ring attached to a jig, I cut both the inner and outer radius of the molding. The adjusta-bility of the jig made this a very easy process and I always felt like I was in compete control during the operation.
I prepared the veneer to make a sunburst pattern for the top, and using my vacuum bag, glued it to a MDF substrate. The next task for the circle jig was to cut out the half moon (Demilune) shape. After drilling a hole where the points meet in top, I attached my circle jig and routed the shape of the top.
With the top cut to shape, I made another segmented ring out of tiger maple that would serve as a solid hardwood border for the top. This also went onto the jig to be cut out. Since I maintained the center hole, I inserted the circle cutting jig into the hole I had used to cut the top. Since I was using a 1/4” bit, all I had to do to get a perfect fit of the inside radius of the border to the out-side radius of the top was turn the micro adjustment .250” to compensate for the bit. Turning the micro adjust knob 5 rotations (each rotation = .050”) gave me an absolutely perfect match of the border to the top. Easy peasy!
The next step was to cut the outside radius of the border, and adjusting the jig to that measurement, I cut the border to its final dimension and glued it to the field of the top.
I needed to create a groove for the 1/16” ebony inlay that would go between the field and border of the top. After installing a 1/16” bit. I adjust the circle jig once again by simply swinging the jig in an arc using the same center hole, a perfect groove was routed between the two areas.
I installed the inlay, added a medallion to the center of the top, and completed the piece. It really came out beautifully and exactly how I pictured it in my minds eye.
I have always depended on the quality and accuracy of the Micro Fence products for installing my inlay, and am very happy that I added the circle jig to my arsenal of tools. The ease of adjustment and the confidence the tool gave me was instrumental in completing this project with the precision required for a project of this type. Thanks Micro Fence!
