I agree with the original poster
...I have ordered some of the router workshop plans and books from Oak Park, but I was able to get a complete set of the large guide bushings from Lee Valley for the same price that oak park wanted for just one bushing ???
The large 1-1/2 OD bushing is great for getting the required depth when using face cutters with the plunge router and templates because it allows the collet of my router to protrude below the routers baseplate...
