TxStars, thats what is feels like I agree with you. But those small bolts and screws could be just fine, check the attached picture, it shows the 16" sct ota on the fornax mount.
If you look close at the picture you will see that they used "Rings" on the 16"
oops I didn't notice it until you mention!
I have asked the guy from AP again, and he keeps saying the dovetail is just fine for direct attachment... but you guys keep reminding me that is necessary for stability...
