    So your not a thinker eh ?

    You seem to be leading down the path of the horizontal model, where both the pull stud, and the collet end are exposed at the same time (as opposed to the pot type),

    Simply add a force gage on the clamp.

    I'm at a point in life where I've realized it isn't profitable to be a thinker.

    This is disturbingly profound...

    Quick doodle model
    Didn’t have time to sketch the plate that slides down to lock the holder in place. The plate would be the size of the face, plus enough extra height for finger holes.

    I would like to add my name to the list, let me know what I can help with. I like the Dorian style.

    I've been planning on doing something like this just because it would be simple to knock out on the mill and I have the needed hardware lying around.

    CAT 40 Tool Holder Tightening Fixture 23-000 - Edge Technology

    Might use a replaceable steel key instead of the machined in place key on the edge version. Easy enough to make one for vertical and one for horizontal.

    I think we can do better than that design.

    It's "pretty", but sure extravagant for a milled project. In steel, you could get essentially the same stability (if not quite the ease of mounting) by just making it from 3/4" or 1" wide stock and having a pair of tapped holes coming in from the bottom for anchoring. Use a scrap piece of plate (and flathead screws) to recreate the right angle, or just come from below if you have a strong bench or similar.

    Do people like the "thin flex band with radial collapse" style of retention? If you tighten the screw enough it's solidly held, but a moment's inattention or extra oil on the surface and it might slide out when working on the toolholder. A flip plate or other visually unambiguous device might be better...

    The upside down U shaped plate not shown in my model above is essentially what you describe. The legs of the U capture the tool holder in the fixture.
    I didn’t realize we were shooting for elegance, I made the incorrect assumption that we wanted quick and easy

    This is one of those rare instances where the end product needs to be cheap, good, and fast

    It would be nice to accomodate a digital caliper for offline tool measurement. Would require an attachment to one of the blades on the caliper to get the reach necessary.

    They make special fixtures for that purpose, using a height gage. I'm thinking about making one here during the holiday if i have the material.

    I thought about making some renishaw probe stands. We have 3 new machines that need them and make our own.

    This the season for tool making.

    I have a fixture for an ISO30 tool holder I really like I could not find it online to get a picture so today I will get some pictures. The fixture is marked HSD which is the maker of my router spindle. The holder holds the tool holder horizontal and has a spring loaded knob that holds the tool holder in place. The ISO30 tool holders I have use 2 flat surfaces rather than the key slots on a CAT40 but it seems that could be redesigned for a couple keys.

    I'm sure we would all love to see photos

    I'd suggest the method of retention- be it a pin or whatever- should be compatible with both standard and Dual Contact holders.

    Or at least it should not prevent a dual contact holder from being setup in the fixture. That's my gripe with the cheapo horizontal/vertical fixture I have now. The horizontal side does not accommodate dual contact holders.
