Pictured above to the right is the  Standard 1/4" X 1 1/2" Stainess Steel Center Pin, the one used with our Circle Jig. It has a 3/8" long spike at one end that is turned to 9/32" diameter (to fit securely into a 1/8" pilot hole).
1/16th Center Pin (Click image to enlarge)	We also now make a 1/16th Center Pin, shown left, which is used with our Center Bar & Levelers accessory, the 1/16th Center Pin needs only a 1/16" pilot hole. When doing "string and berry" inlays, or other geometrically designed inlay task, this smaller pilot hole needed for this pin can be covered by any inlay of greater dimension (e.g. >3/32"), making the pilot holes invisible.
Our  Longer Center Pin is avbailable for our Circle Jig and measures 1/4"X 1 3/4" with a 5/8" spike, and it is pictured below. If you'd prefer a little more security and strength in the Center Pin's installation, (maybe for a larger diameter circle), this pin features a longer spike to seat in your pilot hole and a longer 1/4" post for more "head room" above our Circle Jig's rear trammel bar.
