    123/2 blocks

    123 blocks are very useful devices, both for setups and also for simplifying measurements as I showed here...

    Measuring tapers

    Much of what I do is on a smaller scale, though, so 123 blocks are a bit oversized many times. I decided to make a half-scale set of blocks with dimensions 1/2 - 2/2 - 3/2 or, in simpler nomenclature, 123/2 blocks.



    They're not NASA-grade precision but, even so, they've proven to be very handy indeed. I use them by themselves and also in conjunction with their full-size "parents" on those rare occasions where a larger setup is needed.

    I haven't drilled and tapped them yet. I had planned to wait until a need for holes arose and, so far, it hasn't so they remain blank.

    Marv,

    Great idea, especially the measurement of tapers. The simple approach is always the best.
