Does anyone know what drill size hole is needed for the milk jug washers to fit around the center screw holding the secondary?

I’d like to try it without removing the secondary mirror altogether by cutting a slit across one radius of the washers.

For an AD8 (same as Z8 I assume)

I went to ACE and got two nylon washers, 44mm OD, 16mm ID, 1.5mm in thickness. I cut them just like you suggested at about 5mm, and simply rotate the cuts away from the three thumbscrews.

You only need to cut a single slit. Removing that section isn’t necessary.

Very true, I just didn't want to try and force it through since this is my first scope.  With the two cuts they drop right in, and I didn't have to worry about jacking something up even if I probably wouldn't in the process.
