Topic tags/keywords: jig question tip trick

I have had my leigh super 18 for a couple of years now. I know how fussy they can be to set up. I am stumped on what i am doing wrong to make half blind dovetails on my current project. I have re-centered the guide bushing numerous times, adjusted bit height and wasted more material than i care to admit with setting changes. I hope someone has mastered this process and can help. The manual, dvd and every youtube video have failed to correct the problem. The picture show the problem i am having, the depth is correct but my tails are too narrow. I am using the original leigh bit and ebush at came with the jig. Thank you

I feel your pain. I struggle with my D4 for well over a month. I was doing rabbeted half blind dovetails. Seems I was setting the bit to high in the collet. I kept struggling and finally did get it to work by dropping the bit further out of the collet. I’m decided that another part of my problem was using different woods; oak, poplar and pine. I’m probably all wet about that, but it sure seemed to me like it was an issue. I vowed to never do rabbeted half blinds again. So far I’ve kept my word to myself.

I ended up calling Leigh, they provided the answer. I was using the wrong bit for the depth of cut I was making. On page 30 of the super jig manual it explains which bit to use. The one I needed did not come in the provided set with the jig, I ended up having to order the full set to use the material I have already prepped.
