Just like to say THANKS! to the contributors to this thread who have given me a whole new insight into the usefulness of 123 blocks! I've used them as risers before now, to lift work off the table so you can drill right through; also to lift clamps up when clamping tall workpieces; but the methods described here of finding a taper angle & measuring up round stock are just plain genius. :thumbup: |

Hmmm, I think it may have just become my goal to find a way to drill those buggers out so they work "right". :lol: :proj: Since they are "glass hard" what are the chances a glass drill bit might do it? Hmmm.... off to research. |

My set came from Chronos. I assumed them to be M8 :palm:till I tried an M8 stud in them and realised it wasn't going to work. Since then they have simply been spacers on my mill. I suspect the Chronos ones are Indian and not Chinese. |
| lordedmond:
well they use a tap to make them, I cannot bielive that the had some made just to make the 123 blocks they could be UNC |
