This question comes from being a newbie to the WW scene, I'm still planning out all the projects I want to do over the winter and and also building a list of jigs and such I will need to complete these projects, and I've noticed that most plans/people make them with Baltic Birch plywood. Why would I use this over other type of plywood or MDF? Examples of what I will be making are box joint jig, extension table for my small bench top table saw, cross cut sled, bandsaw resaw jig, possibly a router table and maybe some adjustable in/out feed supports for longer stock.
