    The USS Cairo inspired me to design cannon that could be used to pose with open gun doors. I chose two different cannon to modle; namely the 30 pound Navy Parrot Rifle and the 32 pounder smoothbore. I started with designing the proper carriages and tubes of each.

    Photo 1 - 30 pound Navy Parrot Rifle

    Photo 2 - 32 pounder smoothbore

    At this point, things were looking good. After reducing to 1/250 scale and looking at the parts, it was evident that at scale, the differences were minute. I used the Parrot rifle and smoothed off the breach area. Then converting to a parts page, we finally got a look at the build problems.

    Photo -3 Parts for one cannon. The parts are designed to fold over and glue prior to removal. This gives better regidity for the carriage. Notice the fine detail parts.

    Photo - 4 Starting the build sequence, the carriage sides have been doubled and removed from the parts page as has the cross members.

    Photo 5 - Assemble the carriage by gluing the cross braces between the sides. Roll the barrel with its charaistic taper.

    Photo 6 - Mount the tube on the carriage as shown.

    Photo 7 - Size comparison, that is a normal toothpick laying beside the cannon.

    Photo 8 - On deck ready for action. Notice the #11 Exacto blade for size comparison.

    At 1/250 scale, especially for an interior cannon firing through ports, fine detail is just not visible not is it needed. Take the wheels for example; I included them in the design process and parts output. They were so small, I had to use a small punch to remove them from the paper. Then they were so small that applying them was a chore. Then the look was terrible, looks much better without wheels.

    Get the parts page cleaned up and instructions ready and a page full of the cannon will be available as a free download on Modeling Resource and Downloads

    Enjoy,
