PT-61: Elco 77 Footer with 3D Printing

PT-61, Summer of '42

PT-61, Summer of ’42

My latest completion, PT-61 in 1:24 scale. At almost 39 inches length, the model is large enough for R/C, and is designed as a potential kit for such. However, this build is for display only.

The hull is dual-diagonal planked in 1/32″ basswood over laser-cut bulkheads, but virtually all other parts are 3D printed in acrylic plastics: the cabin shell, turrets, weapons, deck details– all 3D printed. A complete build log can be found on RC Groups: http://www.rcgroups.com/forums/showthread.php?t=2217225

Design references include the original Elco drawings, several excellent books on PT boats, and numerous photos found only online at websites of dedicated PT fans. PT-61 is famous for surviving a direct hit in the bow from a Japanese destroyer’s 5 inch gun while operating near Guadalcanal in late 1942.

The model sits on a replica of Elco’s A-Frame shipping cradle, constructed primarily of wood. The paint scheme, overall 5D dark gray, depicts the boat as-built and as shipped to theater.

Artist's fairly accurate rendition of the damage to PT-61. It's not clear if she carried this camouflage though.

  1. Beautiful model. Always loved the lines of the early Elco. Many years ago, in preparation for my book “U. S. PT Boats of WWII”, I had the distinct pleasure of talking at length with Bob Searls who skippered PT-38 on the same night the 61 boat was hit. He even sent me his sea chest full of dozens of photos he had taken of the boats. What a great guy. His brother Jack was the skipper of the 60 boat that night as I recall. Years later, just for the heck of it, I built a 1/12 scale model of the 77′ hull and pulled a mold that has been stuck up in the rafters ever since. Viewing your amazing work has inspired me to dust it off. With the newer electric technology available, a 77-inch model would look good on the water.
