This 3D-printed main mast is intended to help convert any 1/200 scale Iowa class battleship model kit to the 1950s through early 1980s (pre-modernization) appearance of USS Iowa BB-61 or USS Wisconsin BB-64. Details such as radars, cabling and antenna changed from year-to-year. Details such as radars, cabling and antenna changed from year-to-year.
Advice to correct warped parts: this design includes very long, thin legs that may warp during shipping. Warped parts are caused by the presence of uncured microscopic bits of resin within the parts which is a normal characteristic of 3D printing.
To correct the warp, fix the warped part(s) of the mast to a flat surface with clear plastic or clear tape being careful to position the bent legs in the desired, straight position. Then expose the parts to direct sunlight or a UV lamp for a few hours in order to fully harden the resin. When released from the tape or clear plastic, the now fully hardened parts should retain their straight shape. Ultraviolet light hardens the resin, not heat.
Fully cured, 3D-printed acrylic plastic is brittle and breaks easily. Care is recommended during handling and assembly. To remove the support, very careful use of a common cuticle clipper, or similar tool, is recommended.
Depending on which kit you have, some adjustment of this mast or your kit's parts may be necessary for best fit.
This 3D design is based on 2D plans drawn by Mr. Henry Strub using the latest National Archives research conducted by him as well as exhaustive research conducted by Mr. Rick E. Davis.
