First completed half of a lap joint. Notice that the cross section of the plies is not uniform. This is because the router bit varied in height due to the unnevenness of the guide bevels and the router plate itself, which I had to extend leghtwise in order to get it to work. Also, I added some material to the guide bevels when you compare to the first picture, to give the router bit space to work. I ought to have planned the lap joint rig forehand. For exmaple modelled it out in SolidWorks. If you plan on building a set up, sketch it down first.
