hi, i am gonna make today a parallel and circleguide for my plunge router base. i'll try to keep it as simple as possible using a coupleof plywood bloks and a threaded rod. let's start mechanizing and assembling thetwo parts of the guide. cut the rod with the desired dimensions. make a drill to build the axis of rotation.here we have two choices, insert a pivot like
routers in woodworking, this or use a spreading insert. insert the rods using nuts and wing nuts andit is ready to try a parallel milling. now i am gonna try to mill a circle, to dothat rotate the guide and make a drill to place a bolt which will be used as rotationaxis.
adjusting the depth is so easy, bring therouter down until the router bit touch the wood, and use as reference, something withthe same thickness of the desired depth. it is advisable to wait until the router stopscompletely to remove it. and as you can see, the result is very good.
