The Most Accurate Protractor for Most Critical Vinylphiles in the world

0.065mm line width is reached!

        As said in previous post, there are some fundamental defects in current protractor design in the market, no matter how expensive they are.  They are:
        (1) No reproducibility since the center hole is always designed to be larger than your spindle diameter
        (2) The position of center hole is very difficult to have 100% match to the protractor lines
        (3) The line width is too big (>0.15mm) to be a good reference line for aligning 0.02mm cartridge tip

        I think it is the most precise and accurate protractor design in the market......0.065mm line width with reproducibility and no centering error for all existing turntables in the market!  Quite a convincing and simple solution for centering mechanism (will be disclosed later)!
