I'd call this optical and guaranteed vertical punching http://www.schsm.org/html/marv_klotz_29.html see the next 2 pages to complete your understanding. (I still haven't made mine :) ) Ray |

Cool stuff! Thanks Ray. |
| Fergus OMore:
I've just sent what is as near a copy of George Thomas's simple centreing device 'explanation' and drawing as I dare without infringing copyright. The device is so simple that there is virtually nothing that I can add. Can anyone else- add or explain please? :doh: |
| wongster:
Hi Norman, I received the jpg of the 2 pages, thanks. Can't really read it as the jpg is a little too small and when enlarged, the text is to blur to make out any word. Regards, Wong |
| Fergus OMore:
I'm afraid that for reasons of copyright, I am unable to copy. I deliberately only tried to print the drawing. Simply make a D bit- or don't make one. If you use a bit of .500 round- all you allow for is 0.250 at the edge of the work rather than zero with a centreing device. |
