Chrisrob101,
I'm glad that you've succeeded installing the CF reader, despite the difficultly you've encountered.
Drilling the case is the most time consuming part, and most critical part (I made the mistake too!) of this installation process. I have to admit that I could've done better job. However, I would avoid using glue as substitute.
Here's what I should have done;
1. put masking take on the CF reader where you'll make holes. (CF reader unit must be removed from the chassis beforehand.)
2. Attach the "bar bracket" (I don't know what's called, it the bracket that comes with 2000XL for floppy drive or Zip drive) on the CF reader's chassis, find the right position, then use masking tape to securely attach it, temporarily. YOU have to find the right position where the two holes should be!
3. now make two marks on the masking tape on the CF reader's chassis. (Make marks with the bar bracket)
4. Now make holes, but start with small bit. Use vise!
5. use the screw to see if the hole is the right size. if not proceed with larger bit.

Note, CF reader's chassis is not easy one to drill holes. It is a very hard metal plate. Use new bits and good drill, if you can. And you must use vise!
