I'm working on doing just that so that I can run a series of shallow 6mm (0.236") dados in some 12mm Baltic birch plywood (BBP). I have six grooves to cut on six sides which will become the sides of storage racks for some divider boxes for sorting and storing fasteners. 6mm BBP will inserted and glued into the grooves as shelf guides/supports. I will be using a standard combo blade on my Sawstop Jobsite saw with a 1/8" kerf. The first cut will be made for all the grooves and then the LS will be use to shift the cut enough to make the resulting width a nice fit for the 6mm BBP.
I have a DeWalt dado set but the narrowest it will cut is 1/4" (0.250"). I considered using just one of the two outside blades to get a flat bottom, but figured out the "bats ears" bottom left by the standard combo blade works just fine.
My approach is to add an extension onto my crosscut sled onto which the LS base will be mounted. I have the 17" LS model but the fence is too wide for my sled, so I will use the fence from a Kreg bandsaw fence that I'm not using on my bandsaw.
I've been thinking about what hazards this configuration/use might present. Such as trapping the BBP between the blade and the fence. These are not thru cuts, but dados. The nominal method of guiding the stock would be with a miter gauge (Incra 1000SE) but that seems less secure than holding the stock on the sled. The miter gauge would have to be moved from the left miter slot to the right once the stock is moved over to the right for the last few dados and the stock will be less than fully supported on one side for each cut. Having the stock supported on both sides of the cut for all of the cuts seems like a good
situation.
Pictured below are the parts set up as the mount will end up. I'm working on making braces to hold the extension to the sled and there are challenges caused by a mismatch between the LS fence mounting screws and the Kreg fence "T" slot.
I would like to hear your thoughts about the veracity of this approach and in particular hazards that should be anticipated.
