What a great thing to have!!! As I mentioned at the start of my build I'm following the building as described in the book "How to build Academy's USS Oliver Hazard Perry Model" by Glenn Hoover. The book details building both with the Pontos photo etch and without. I strongly suggest building the books as it details exact build process and many "how to" suggestions within its 243 pages. The Academy kit with Pontos is available at Squadron Hobbies if it is of interest.

Just a quick update. The main mast cross sections have been added and now waiting for the epoxy to set. Next will be adding the cross section under supports.
A picture is a thousand words when you look at the masts.
