Seems no matter what adjustment I made on the D4R Pro, I could not get rid of a small gap on the right side of all my Half Blind Dove Tails. After dozens of test cuts and few calls to Leigh, I finally found the culprit. The gap always occurred on the side of the joint, that relates to the side that sits closest to the left HB Pin Scale, when the Pin Board is mounted up. What I realized was that, as the router base travels up the fingers during the cut, the left side of the base was riding up onto the HB Scale, which it should do. Problem is, there's a raised rim around the outer edge of the scale that the Scale decal sits inside of. Well, that raised rim is high enough to cause the router base to lift as it travels over it, which causes a shallower cut on that side of the joint, which causes the gap. I hope those with the jig will understand my explanation.
My fix was to file down the rim on all of the Scales. Now, I'm happy to report that the gap is gone. Thing is, I don't know if this is just a problem with my particular jig or if others have had the same issue and just regarded it as no big deal. Please let me know if you've seen anything like this on your D4R Pro cut dovetails.image1-3.jpg
