How to determine the proper eccentric offset?
Any one have a design for a holder for a router to use the tool rest support to hold a small trim router to cut flute?
My plan is to set stops on the way tubes for enter and exit positions and drag the carriage down the leg for perfect flutes. Way short on time so I am trying to shorten the learning curve.
Short dowel size of tool post with hole in center
Flat scrap of plywood bolted to dowel with a couple of small beveled strips to lock router barrel in place
Non-slip material and a 4" hose clamp to hold it together
I cut flutes in 3 steps:
Right to left from off blank to maximum depth
Right to left from off blank to finish feathering out flute since I wasn't deep enough at start
Carriage locked, left to right from off blank swinging in an arc to meet maximum depth.
Now, having learned what the jig will do, I would start off of the blank on the left, swing into cut and slide down the length of the flute and feather out off of the blank. Time did not permit experimentation or screwing up a $20 dollar blank and starting over. I have a little more carving to do on the face of the blank and a little clean up before delivering the goods tomorrow.
