I am manufacturing a product for my wife's quilt shop business. The base of which is 1/2" baltic birch that is 3" wide by either 12" or 20" long with a dado that is 1 5/16" wide by 1/4" deep dado. I've been cutting these on my table saw with a stacked dado but after doing over 1000 and many more to come, I'm open to your ideas on machinery that would make this repetative process easier and faster. Or am I left with pushing it through the table saw? Any ideas will be appreciated. Thanks a bunch.
