    The 3rd hand. Very handy if you dont hold a mic every day and have a technique

    I got basically the same one except the anvil and the spindle are both tapered. Much better for short neck cases.

    Seems common to jump on this shortcut, but there is a fundamental flaw in it that still needs to be fixed.
    New necks taper in thickness. Donut area thicker than mouths.
    So for neck measure to compare case to case a datum point has to be established.
    For this you need mouth stop.
    And for tight measure near shoulders, you need only adjust anvil ball contact with spindle face. Which means you need an adjustable anvil.

    What I've used for a few years (been discontinued; I got mine for Christmas from my wife):

    Has a vertically-adjustable anvil but no mouth stop. Works great (though the Amazon device probably costs less...).

    'K, so you fabricated an attachment to the same tool I have, eh?

    I think such is within my capabilities... think I'll do that. Thanks!

    spclark, I have the same Sinclair digital micrometer and put some plastic washers of different diameters that fit snug over the anvil to give me a mouth stop. If I had to use two or three, I put a dab of glue between them to keep them from individually moving. This way I can take them on and of for different cases. Works great for me.

    Great idea kerjo!

    I did something similar with a ‘blade’ mic for gaging case head and/or extractor groove expansion after initial firing. Mount the mic on a suitable base, add shims to control point on case at the blades level.

    I would hate to start over when it comes to Micrometers, I though I had ball micrometers and then I found out someone has started calling tube micrometers a ball micrometers. And then there was the digital head space gage that looks like my dial indicator holder stands and I have comparators.

    I wonder why they discontinued that model. Looks very nice.
