I am wondering if my elliptical bushings will work well with other jigs. I purchased a Leigh R9 Plus dovetail/box joint jig which I have yet to try. Not because I haven't wanted to but because 12 acres and three mobile homes takes up just altogether too much time. Anyhow I am intrigued by their introduction of these elliptical bushings. From your users experience, how well do they work? It would appear obvious from their geometry that one must hold them in the same straight position throughout the cut. It would seem also that if they work well with their intended R-9 partner then they should work well with any jig intended for use with bushings/vs bearings. So, have any of our members gone there who care to talk about it? It took me all of no time at all to formulate the question while reading the manual prior to purchasing the system. Given that I am neither a genius nor any kind of engineer, then surely someone with more time on his or her hands has already tried it. And never having been to any forum before, I have no idea where I go next.
