I have Ron Paulk's plans for the workbench and the total station and something else, maybe the Kapex station. But I haven't built any of them. I used the ideas to make a 3 foot by 7 foot workbench/outfeed table. I also built a 2 foot by 7 foot side table for my RAS/CMS table with a flush mount flip stop track like the total station uses. I really like those flip stops, great design. And it lets me use that table for other things easily.
I also like Ron's video series on doing crown molding. His jigs are all worth making. I've done crown several times without his setup but it's easier with it. They are all simple little things made of scrap plywood. That's one of the great things about Ron Paulk's ideas, they are all realitively simple and inexpensive but most of all they work.
