I needed a way to cut straight dadoes for a project still sitting in the corner…......borrowed this idea from a plan posted on the web….....

Made from a 1”x6”x4’ board…....ripped in half….then cut to 2 1/4”......sized to 18” for the stop and 24” for the guides
A 3/8” drill was used to start and end the slot on the guides….then a 3/8” router bit to finish.

the stop was made from the 18” pieces…......glued and nailed together

a piece of 2”x2”x12” was used for the clamp…...drilled for 5/16” bolts

guides were glued and nailed to the stop…...6” apart (the diameter of my router base)

attach bolts and bar knobs and voila… cost…....$7.00 for knobs…..bolts and wood from other projects

Works for what I need to do!!!

looks real nice , doug .

maybe some sandpaper on the inner edges of the side rails ,
to keep it from vibrating around ( 80 grit ) ?

If you were to let your router run into the end stop to cut a groove in it, you would then have a handy reference to help with alignin the dado location correctly on your workpiece. No measuring for offset of the router base ever again. Just mark where you want your dado to be and then simply line up the notch in the end piece wth your marks.
