Let me start off that I have great respect and admiration for handcut dovetails!! BUT, for me I need to get them done quickly given the number of pieces I produce. Currently I use the Leigh super 18 jig which is ok but I find it requires a level of fine tuning that does the opposite of saving me time. I cam across a review in FWW for the Keller system and wanted to get opinions on this – anyone have it, is it as seamless as the reviews suggest? Thanks for you views on this.
