So far, I've used sliding dovetails for a couple of 12" deep drawers to attach the drawer face to the drawer sides, and also the back wall of the drawer to the sides. Since the sliding dovetails were just 12" long, they slid together fine and seem to have glued up nicely. The dovetail groove in the face and back pieces cut fine with no tear-out. However, I did get terrible tear-out when cutting the male part of the dovetail in the ends of the side pieces. I solved that by scoring both sides with the table saw prior to cutting the tails on the router table. Probably could have scored with a sharp knife instead. I got a 7 degree dovetail bit now and for fun I will try a longer sliding dovetail instead of a dado for the next drawer's floor-to-sides joint - that will be a 23" long joint. I suspect I'll find that the joint needs to be rather loose in order to slide together, in which case it may not be very strong. If it doesn't work nicely then I'll just use a dado. No need for a tapered sliding dovetail for these shop cabinets.
