    Another Lost Art 3 Points

    No. Airy points for a rectangular plate would be 1/4 to 1/5 of the 33 inch dimension. So 33*.22≈7.26 from both edges and in 7.26 from the end, with third point centered and at 7.26 from that end. Sent from my iPad using Tapatalk

    FS: Monarch 6" Buck Set-Tru, 3-jaw chuck

    Keep shopping until you find one with removable top jaws. I opted for a nine inch buck chuck for my 10ee. Miss that little pig! Sent from my Pixel 2 XL using Tapatalk

    How to calculate true position

    In a nutshell, troupe is the same as the clearance of the mating part. If you have 1/4 inch screws fastening two components together, the clearance holes dimensioned at .265 dia, the true position would be .015. For dowels, much tighter. Sent from my Pixel 2 XL using Tapatalk
