    Making cannons from non-traditional materials

    in Discussion for a Ship's Deck Furniture, Guns, boats and other Fittings

    Posted

    Thank-you everyone for taking the time to help!

     

    Bob: I haven't totally ruled out metal yet. If my next few tries with resin don't work, then that may be next.

     

    Steve: I did paint both sides of the mold first, but will try "CPR" on it next time. Goodness knows they certainly need resuscitation!  :D

    I've made a couple of 2 barrel molds, and the setup time is about 8-10 minutes.

     

    Ed: I am seriously considering metal as an alternative, but would like to give the resin another couple of tries using the advice given. 

    I've included a few photos of my molds and some of the rejected barrels. 

     

    The barrels look better in the photos than they really are, at least they don't look good to me.

    Okay, I think I'm ready to fire my cannons.......................out the window that is!

     

    I have tried casting with mixed results, none of which has yielded the end product that I deem acceptable for mass production! I have come to the conclusion that the biggest challenge has been casting at such a small scale - 1/96. These things are tiny! The problem arises in trying to pour/force the resin into the 2 part mold. Because the scale is so small, the pour hole has to be kept relatively small as well, and thus the problem. Just out of frustration, I tried filling the cavity in each half mold and then "slapping" them together.....believe it or not, this gave the best results, but still not exactly what I want. I will try to post a pic of the trials later. The diluted Vaseline worked quite well as a release agent and sticking was never an issue. 

     

    For the curious, I used polyester casting resin and RTV rubber molds.

     

    I may keep experimenting, or try something totally different - I am DETERMINED to make these things myself!

About the NRG

If you enjoy building ship models that are historically accurate as well as beautiful, then The Nautical Research Guild (NRG) is just right for you.

The Guild is a non-profit educational organization whose mission is to “Advance Ship Modeling Through Research”. We provide support to our members in their efforts to raise the quality of their model ships.

The Nautical Research Guild has published our world-renowned quarterly magazine, The Nautical Research Journal, since 1955. The pages of the Journal are full of articles by accomplished ship modelers who show you how they create those exquisite details on their models, and by maritime historians who show you the correct details to build. The Journal is available in both print and digital editions. Go to the NRG web site (www.thenrg.org) to download a complimentary digital copy of the Journal. The NRG also publishes plan sets, books and compilations of back issues of the Journal and the former Ships in Scale and Model Ship Builder magazines.
