Slowly but surely my trestle table is coming together. After edge joining six planks I cut a wide tenon at each end with my router leaving a raised ridge on the outer edge to support my router base during the cut. I then cut the tenon to the finished 45mm length and cut out the two locking tenons leaving the shorter edge behind. The end mortise started as a 10m x 6mm groove cut on my router table and then the two deeper sections roughed out on the drill press and clean out by hand with my mortising chisel. Once fitted together I drilled holes and cut two hardwood locking pins and glued everything together.
