I'm getting ready to start a couple projects as soon as my hardware arrives. I have a new baby girl coming soon and I want to build her a cradle and a crib. My question is, I have no experience with mortise and tenon joints. Based on my research, most people make those joints with a router or a table saw. I have both. I was looking into mortise and tenon jigs for my router but they are very pricey. What is the best way to make nice tight mortise and tenon joints without buying a $300 jig?
