I needed 30 2" diameter x 1/2" thick pucks, with slight concaves on both faces. Below is how I did it, but is there a better way?
1. Cut 2 1/4" x 1/2" square blanks for the stock (maple)
2. Mount a chunk o' wood to a faceplate and turn (taper) the free end down to a 2" diameter.
3. Sandwich the blank between the taper and the tailstock (the tailstock leaves a small indent on the face, but I take that out later when doing the concave).
4. Turn the blanks down to the 2" diameter
5. Replace the faceplate with a 4 jaw chuck and chuck in the blanks (I used a spacer so the blank is proud of the jaws by about 1/4"). Also used some plastic to keep the jaws from damaging the edges.
6. Make the face concave, flip the piece over and make the other face concave.
So what do you think? I'd still like to BLO the pieces and then friction wax them, so I suppose I can repeat the above steps...
