I have 5 junk OM screens. If someone wants to try this, I'll mail each of
the first 4 respondents a test screen (If you're in the 50 states or
Canada.).

Subject: Re: [OM] Modifying Olympus Screen
| Carefully following John's procedures, I scribed grids on a 2-13
| screen. Though I've got nervous with the work, I succeeded. Thanks
| John!
|
| BTW, I had a little trouble with making the template, so I used
| Corel Draw to draw a 36 x 26 mm box with 6 mm grids. I think this is
| finer than the 1-10 screen, guessing from the drawing?
|
| First I practiced with a junk screen, and then bought a new 2-13
| screen, and scribed lines on a used 2-13 screen. I don't want to do
| it again ...
