Bob...
I haven't built an O scale Walthers HW kit recently....last one was about 35 years ago for an acquaintance...but I have more recently constructed several HO kits. I agree that the roofs can be challenging. But I found a better solution not long ago for both easily removable roofs as well as better interior lighting...
For attaching the roofs...forget traditional fasteners... long machine screws, etc. going from floor to ceiling. I have become a magnet fanatic. I'm not talking about traditional, cheap ceramic magnets. I'm referring to the super-strong neodymium-iron-boron ones that come in a variety of very small sizes. Our (LHS) principal sales for these are through the Games Dept.. Apparently gamers love them for keeping their game pieces in position, or for creating adjustable limbs, weapon attachments, etc.. They're hard to keep in stock, they're so popular.
On a passenger car for which a removable roof is appropriate, I simply embed two to four of these tiny magnets in the roof or on top of an interior bulkhead. They can be paired with either a small piece of ferritic steel (e.g., common washer) or with another magnet. Of course, with the latter...two magnets...you must determine the polarity of the mating pair and install them keeping the poles aligned so they will attract....not repel!!. A mated pair of these magnets has AWESOME holding power for a situation such as this.
Re the lighting...I use LED strip lighting as made by Miniatronics, Viesmann, et al. It fits neatly into the clerestory area of a HW car, and is not a bad fit on an arched roof, either. The electrical connections I deal with using miniature 2-wire inline connectors available from several sources (I use Miniatronics).
Returning to the magnets.... I most recently used them on an O scale Ambroid wood caboose model to give interior access. In this case, especially due to the intricate end ladders, etc., I used the tiny powerful magnets to make a detachable caboose side wall. It's really cool for providing access for detailing, lighting, etc.. I used magnet pairs in this case, and, man, do they ever hold fast!!! Later I used the small magnets to hold some pedestrian figures in place around a structure that I necessarily must access the interior occasionally.
The magnets I most commonly use are by Primal Horizon. The package of 25 magnets 3/16"dia. by 1/16" thick cost $15.99. They make sizes from 1/16"dia. to 3/8" dia.. Their website is www.primalhorizon.com.
I also use Magcraft super strength magnets, also offered in a variety of sizes/shapes. Website www.magcraft.com. The package I'm looking at has 14 disc magnets .500" dia. and .125" thick, $9.99.
Once you try using these incredibly strong tiny magnets, you also might get 'hooked' on other uses.
FWIW, always...
