Are your barrels wood or metal. Each can offer different finish options. Modern gun bluing is actually that: a dark blue almost black as you have probably seen. I don't actually know what the finish was on gun barrels that were not bronze in the 1800's. It may be a similar speculation to what the actual surface color of decks were that were holy stoned regularly and not as we see them in "walk-on" tours of the old ships now. I'll check with my younger brother who is a walking encyclopedia of ships of war, British and French from the Napoleonic era. The works of Jean Boudriot may give some information. PT-2
I have attached a photo of the steel barrel cannon that I turned 40 years ago but only fired it for the first time today with a black powder charge for a 9/32 inch ball bearing. Even with a 2/3 charge starting trial it was very effective in the shot. This finish may be something like you are looking toward but I cannot say a paint color so your prior suggestions in trials will lead you to your desired appearance. Scale will also be factor. This barrel is 5-3/4 x 7/8 inch max diameter. Not having the carriage completed I used an F-clampPT-2Thats a good idea Jim, think I will try that technique.
Brian,I swear on using TAMIYA flat black and graphite powder afterwards.
What will be your color for the carriages? IT seems that they changed over the changes of whom so ever was in command or carrying the flag. PT=2Thank you Janos and PT-2. I think the simplest approach of matt black and rub with graphite is the way I will proceed.
I can understand that decision. Sounds like matching the tone of the other wood in the build. If you went to one of the historical colors it could really clash and stand out with what you have overall. PT=2They are boxwood carriages, so I will just coat them with a clear poly varnish.
