......That should do the trick (assuming that the sleeve from TnT cones in at 1.25 inches), especially since the Uni-bit probably has a step at 1 inch, which would center the hole.
The tube is 1 inch, and the sleeve is also CF, and has a 1" inside diameter, (or slightly more...just enough to allow it to slide inside). Ask wherever you buy your tube for ANOTHER CF tube [that can be used as a sleeve], that exactly fits the 1" tube...remember this is an exact fit, and there is no "slop" between the tube and the sleeve. The outside sleeve is no more than 1/16" thick, so your holes would need to be around 1-1/16".
Maybe I can find some close-up photos of the tube/sleeve arrangement, (though we aren't building the fuselage now).

If I am not mistaken, wouldn't the hole have to be 1-1/8" in diameter if the sleeve has a wall thickness of 1/16"?
