Some more generic tools I already had, such as the air compressor. However many tools are unusable because they are metric and the Van’s aircraft RV-7 kit coming from the U.S.A. (still) uses the imperial units. Also I found that even my Dutch (old) compressor was using an outdated connector type called Orion and apparently this was changed to Euro. They look very similar and almost fit, but when I was considering hammering the connector in there, I consulted the Internet.
It’s possible to buy all the tools of the Van’s “tool list” separately from suppliers, however I decided to take a shortcut there and order the “Oshkosh Full RV Tool Kit” of Isham, with some extra options.
