The official JustC what is this tool thread (1-6)

JustC
OK,..my grandfather taught himself engineering and fabrication and worked in the aviation industry for some time designing parts etc. He has lots of tools I can't identify, so I need your help with what these are and how they work.

    Looks like you have some pretty neat tools there...don't have a clue what they might be...except for the last one. It looks like it might be a scribe of some kind.?.?

    #4 and #6 would both be circle scribes...think along the lines of the compass used in art class for makeing circles
    the rest are all various clamps, probably used on a milling machine of some type with the exception of #3 which looks lie a corner jig used to align two parts to form a corner perfectly square

    good call on number 4. Dad told me that Pop designed this tool himself for transferring scale drawings to full size when using paper treated with wax as a template. But that is the only info I have.

    BTW, this is only a small fraction,..more to come.

    #1 and #3 look like scale clamps.
    #3 looks like a clamp to align 2 scales at 90degrees.
    #1 looks like a scale stop

    +1 for MVP

    Pic #3 is for setting two scales at 90 degrees. One scale will have a grove in it (for clamping in a square head), and the second scale will be lighter and non grooved (12" or 300 mm scale will work).

    Pic #4 shows what is commonly called a "trammel" (like a beam compass, only without the pencil/pen). On second look, it appears to be a measuring devise for measuring the ID and ODs of BIG items. The crooked legs taped to the beam are for use taking ID measurements, then this is used with a large (VERY!) micrometer to get the measurement. The mechanism on the left side is used to get the rough size, then the inside clamp is locked down and the fine threaded adjuster is used to get the measurement. (the outer piece is allowed to float for this) Like the vernier adjuster on a height gauge.

    Pic #6 shows a Beam Compass with attachments and two probes for a multi meter (red and black objects on the left) I believe that the Beam attachments are on the shipping/storage block. Somewhere, I'm sure, was a longer beam. Commonly found in a wood shop.

    I see some depth guages in the last pics....but some things look like draftsman tools and some from the machine shop. Crafty people can take a can opener and make it part of the ignition of a car. Whatever the tools were meant to do.....he probobly didn't use it for that. It like finding a steno machine in an Ostrich farm....you KNOW what it is....but what the heck was the farmer doing with it?

    #1 and #3 are both rule clamps as already said. The bottom one in #1 is a Starret one, Part no 299 and the Angle one is 298 I believe. Both are worth about $15. I have one of the clamps right beside my computer now. They look cool, and really don't serve a purpose. But with #3 you can make a square out of two rules so I guess it has some usefulness. The top one in #1 looks like a Lufkin, which isn't worth anything.

    shoff14, you are correct about the starret items. I have many more to take pics of yet. I am trying to keep "like" things in the pics.

    # 1 & #2 look like clamps for a machinist vise. You clamp them to the jaw of the milling machine vise and the parts are always at the same spot when you start to mill or drill.

    #6 are trammel points.

    That truly is what they look like and what some people use them for however, they were designed as rule clamps so you could hold your rule. Starrett still list them in their online catalog even though they haven't been made in years.

    #1 are scale clamps to combine scales for longer lengths.

    #2 are vice stops to clamp to the fixed jaw of a mill vice.

    #3 is a right angle or "square" scale clamp.

    #4 and #6 are circle scribes for layout work.

    #5 is a puzzel to me, but may be a jig or fixture clamp of some kind.
