Hint; you should electroplate the white metal prop with nickel, bronze, etc, so it will be much resistant to damage.
Since you already have the kit, you should take a look a cabal report #12. This report talks about the skipjack's WTC and has loads of pictures. There is more in that report, it is not just about the skipjack, but also about the development of other subs too, you know.http://support.caswellplating.com/index ... 2-jan-2012
Also post your build here and on the Caswell forum too. David and Mike are always on their forum and from what I remember, their names are "He who shall not be named".
Hope the report helps you some.
