    They may be wheel truing tools for a universal grinder. These are called brake wheels. If so,they go in the work holder and are put against the wheel to make it evenly flat. After flattening, the wheel has to be dressed.

    The Huntington wheel is for truing and sharpening bench grinders. I am not certain that the tools I identified as for universal grinding wheels are that but I still believe they are.

    If they are as I suggest, they are missing the silicon carbide disks that mount between the metal disks. This arrangement is used to true a composition diamond wheel. If I have the identification right, this tool trues the wheel on a universal grinder, That is, it eliminates the run out. After truing, the wheel still has to be dressed.

    Hi Dr.Jon
    If you watch the second picture you can see that the b8 tool has the disks which are converging and I guess that no material is allowed between them.

    Hi motormaker,
    Riveting tooling? Can you please give some more details on how the instruments work.

    Warmest regards.
    Carlo

    HI Carloclock

    You are right and I missed that detail.
    Now I suggest these are different tools.

    My new idea for the B8 tool is that it is for burnishing. It would be used to burnish a blunt tool tip . As Motormaker suggests, the tool could be used to secure a rivet. It would be brought against the end and pressed and rotated to form a rivet head

    The W12 tool might be for wheel truing. If the two wheel inside can be separated a carbide disk could be inserted. If the two wheel are a single piece also could be for wheel truing but for sindered wheels rather than composition wheels.

    Hi Dr.Jon ,
    Just for the pleasure of talking! (...and do not forget the first part of my signature block, I have just a basic knowledge of your language and I could run into some unwanted interpretative quibbles )

    I do not agree on both replies. In b8 tool the front surfaces are not enough flat ( they are convergent) , or to the contrary too flat to exert a burnishing action by pressure on a tip .
    On the same manner the surfaces are too flat to form a reasonable and reliable head on a rivet.

    This looks like to be reasonable. Even if we consider the extra empty space on the tool at the back of the disks.

    By the way it was a very nice talking to you.
    Warmest Regards.
    Carlo

    PS
    Dr.Jon, I have some language doubts for the engraving words for my replica of the cosmochronotrope I have recently built. Can you please contact me at the address you can read at the bottom in the home page of my site (the label is "contattatemi". Thanks in advance)
