After having received the second lot of Robart hinges I’ve spent Saturday afternoon locating the positions of them and drilling and countersinking the holes on the inner dome. My method of fixing the correct position for the hinges improved with every panel. In the end I taped them down with some strong double-sided tape and then put a few layers of frog tape on top. Then drilled all the way through tapes, hinge holes and through the inner dome from the inside, countersinking from the outside and voilà: nice fit. With the earlier ones I often ended up having to take the (inner dome) panel off again and sand back a lot as it ended up twisted and catching on the hole in the inner dome. Next is spraying the remaining outer dome panels blue, give them two coats of lacquer and mount them onto the hinged panels. For the mounting I’m using strong doublesided tape by 3M. That allows me in the future (if ever needed) to take them off and have access to the screws of the hinges.
