123/2 blocks
123 blocks are very useful devices, both for setups and also for simplifying measurements as I showed here...
http://www.homemadetools.net/forum/m...g-tapers-55135
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.

Thanks Marve; I have been machining for a long time, and have never seen this process explained so simply. This shows that you are never to old to learn!!!
