When we think of router lift's, we see lots of closely machined metal. But the ShopNotes (issue 122,) / Woodsmith router lift is mostly made from wood. Steve Ramsey has an excellent video of his build, plus Woodsmith also has a video. Just about got mine completed. Working on mounting to router table insert. Main deviation from plans was to tap end of threaded rod for a 3/8-16 bolt, turn hex coupler round, and use "V" groove bit on Sears molding head to cut the track parts. Also bought a couple of regular nuts,( to make a jam nut assembly,) from Fastenal to make adding stop nut to threaded rod easier. You have to thread a stop nut down almost the entire length (12" - 3/4-16 ) threaded rod. About two hundred revolutions. An impact gun makes quick work of this
