the hull is vacuform as are the funnels Everything else is pretty much scratch. A few questions. I need to cast some resin parts. What's best? Second. Conflicting references on rear main gun position on main deck or on upper deck. Anyone know for sure?
I like Smooth-On
https://www.smooth-on.com/
Check the site for videos & descriptions on their various products. They also have how-to instructions for molding & casting.
I use their OOMOO-30 RTV and Smooth-Cast plastic. The nice thing about these products is that they are a 1:1 mix (+/- 10%). You don't need the precision of a 10:1 mix needed for some other products. Smooth-Cast gives a smooth finish with few bubbles. I have found that Alumilite produces a coarser finish. It is useable but takes a bit more practice.
See to the Distributor list. If there is one nearby you can purchase over the counter. I have found that the counter help are technically savvy and can give you good recommendations on materials & methods.
A couple of references:
Al Adcock "US Flush Deck Destroyers Inaction" Squadron. has a lot of photos & line drawings of 4-pipers, all versions. Cover art is the Ward engaging the Japanese sub at Pearl Harbor.
Glen Arnold "Warship Perspectives: Flush Deck Destroyers in World War Two" WR Press. has more photos & drawings, all versions. There are a lot more detail photos. There is a good fold-out set of plans for HMS Montgomery. They will get you deckhouse configurations.
Lott & Sumrall "USS Ward Fires First Shot WWII" Impressions, Inc. For the Ward at Pearl Harbor, this book is mostly drawings with several photos which are seen elsewhere (Navsource). There are photos of the guncrew and the first-shot gun. There is more info on the Ward as an APD. (Interesting factoid: LT Outerbridge (later Admiral) CO of the Ward at Pearl Harbor was, in 1944, the CO of the O'Brien and ordered the sinking of the APD Ward after she was mortally damaged during the Leyte campaign.)
Delgado et.al. "The Lost Submarines of Pearl Harbor". TAMU Press. One chapter on the Ward's action at Pearl Harbor. No additional unique photos or drawings. The cover art is the Freeman painting of the attack which is mentioned as being seen on Navsource.
