chrisman Posted June 6, 2013 Posted June 6, 2013 (edited) Hi All For a long time I had a passion for naval cannons espessially the 24 pownder and a few months ago I happened to get in my hands some naval bronze rods so I decided to make a 12 inch cannon barrel with a carriage . The outcome was so good so I had to make two more bigger sizes up to 29 inch long .It was a really hard work and time consuming both the cannon barrels and the carriage plus I had to do all brass hardware for the carriage .The cannons are fully functional Edited June 6, 2013 by chrisman
Bobosan Posted June 6, 2013 Posted June 6, 2013 WOW! Very, very nice Chris! Many questions - What kind of wood? Is that a blued steel barrel next to the bronze? How does bronze expansion compare to brass or steel for cannon use? If I see it correctly, is that 1.110 inch caliber?
LTUPyro Posted June 6, 2013 Posted June 6, 2013 That's amazing work! How long did it take to make this?
chrisman Posted June 6, 2013 Author Posted June 6, 2013 Thank you guys for your kind words. The wood is black walnut . The brown tan barrel next to the bronze is a brass barrel and the tan came natural after firing the cannon 40-50 times Also I made this barrel with a thinner wall ,than the rest of my barrels, and I safely abused it a lot just to see how it will hold and up to date it must fired 200 led balls with no sign of wear . I am not sure what you mean by expansion but if you mean thermal expansion for yellow brass is around 11.3 , for naval bronze around 11.8 and for stainless steel 304 is 9.6 microinch. I v also made a barrel from stainless steel and the only difference with an equivelant bronze or brass barrel so far is the sound ,higher pich tone for ss and lower for brass . Also brass tends to have a short echo after the bang . Yes the actual barrel caliber is 1.110 inch. It took me around 100 hours for each cannon with more than 150 machined brass and wooden parts for each one
Oinikis Posted June 6, 2013 Posted June 6, 2013 wow, that will eat some powder. but satisfaction is guaranteed. verry well done, very beatifull.
Bobosan Posted June 6, 2013 Posted June 6, 2013 Yeah, wondered what unique qualities the naval bronze had. Interesting about the sound difference. Did you scale down plans from an original? Very nice cannon indeed!
marks265 Posted June 6, 2013 Posted June 6, 2013 You made me say "I WANT ONE!" However, after a quick cash flow check I will have to pass. Very nice job, it is a collection to be proud of. Mark
chrisman Posted June 7, 2013 Author Posted June 7, 2013 Thanks folks. It's really rewarding to me to hear all your good comments after all the hard work i put into those cannons I will try and post a video soon and some more photos of them completely finished . I have used plans for cannon and carriage so as to be as accurate as possible to the original but i did deviate from the original plans by thickening the diameter at the breech a little for extra safety
JFeve81 Posted June 7, 2013 Posted June 7, 2013 Wow! Very nice cannons. I want one. At least wish I had the capabilities to make one. Great job.
chrisman Posted June 12, 2013 Author Posted June 12, 2013 Here is some more photos of the my medium sized cannon almost finished. Need to polish the barrel put oil the carriage and a few small details. The barrel is 19inch and the total weight for barrel and carriage is 14kg ,31pounds. Caliber is .95 inch. [attach
Bobosan Posted June 12, 2013 Posted June 12, 2013 Another nice piece, chrisman. Now I know what my 3 black walnut trees would look like in a project.
chrisman Posted June 12, 2013 Author Posted June 12, 2013 Thanks Bob . No not the poor trees . I ll try and post a video to see it in action
