Baird's hole drilling
Posted: Fri Jun 15, 2007 6:44 pm
In the 30 line Baird system, he increased the spacing of the first and last two rows of holes to get a wider picture.
To prevent black lines he must have also increased the diameter of these four rows of holes too.
I wonder if he drilled all the 30 rows of holes the same size then redrilled the four rows larger or changed the drill to a larger size whilst initially drilling all the holes?
Also, did Baird actually make all his many discs himself or get an engineering firm to do the work? If so, I wonder who the engineers were?
Now the above just shows what odd ball things go through this mind of mine!
