As for ribs, being a "tight Tyke" I use a template to cut the ribs from a sheet and put them together for finish sanding. Spar slots are cut/filed out while the ribs are held as a block and. like yours, checked for size with the appropriate strip.

*** Well spotted Malcolm,the outlines are made from either thick card or in this case balsa,three to four strips of 1=32nd by three sixteenth balsa strips are wound wet and left pinned overnight,the next day they are unpinned and then glued together,left to dry again and sanded,result one very strong and light wingtip,having used this on models from a few feet to several feet I can testify the bouncability !
Sometimes with larger models sets of parts made up like this are compromised and just say the essential formers,spine etc are kitted,the rest of the 'cut & try' bits are added as required,but still the semi kitting comes in useful.
I used to use reed cane steamed around a candle,you can still use this idea,go to a pound shop and buy a cheap Chinese mini blind,take it home and cut the braids which join the blind together,you will have enough material to last for years of model building.
I also like your idea of over-sizing the ribs and then finishing off after bolting together,I use threaded rod from a Meccano set for this.
Pre kitting is a good way also of maintaining interest in your subject,the sight of those nicely sanded bits makes you want to get on with the build.
