Thinking of attaching a dovetail bar to an ETX105...

Hi everyone. 

Below are some images of my 're-modded' ETX105.

I am thinking [and taking a risk], of attaching the dovetail bar by drilling into the tube a securing with some 1/4" BSW countersunk screws/bolts with the countersunk head being on the inside of tube or using the four machine screws that are supplied at the ends, (again with the head being inside the tube), and doing away with the Jubilee/hose rings. What do you guys and girls think?      

I know it means removing the the mirror and meniscus cell before I proceed. I have the tools, but do not have a workshop/shed to carry out such a task.

Any ideas most welcome... or do you think I should leave it as it is?

The nuts are normaly on the inside. Or you could drill and tap the holes in the wall of the tube if it is thick enough. M5 screws are more than strong enough.

Also you could drill new smaller holes in the dovetail bar and use countersunk screws.

Thank you @johninderby.

I am/was thinking of utilising the 1/4" threads from the dovetail, hence the reason for the screwheads being inside the tube.
Forgot to mention that if I do proceed, that I will be using 'Allen'/hex machine screws!
