I drew the print from the pics ......and the postive from the print . It will have a 1" bore .

I'll make a mold and cast some big wax !

Nice lines!

It'll be one to pass on to many generations!

Wow! I love it! Thank you Gary for doing this for me. This cannon has a pretty unique history and is important to me. I can't wait to see what it looks like in bronze. Thank you Gary.

The trunnions look too large to me on the pattern. Were they larger than the relatively standard bore diameter?

Good work Gary! I like the detail.

I left them maybe abit large . That was because I never saw the truions , they can be turned some but other than a loose 1 cal rule I couldnt say .

I'll sit and stare at it all night

and decide in the morning ,the rimbases will remain the same .

Thanks for the complents Zulu ,spuddy, and CW .

Gary

Looks Good,Gary!

What will the finished bore diameter be?

RocklockI · « **Reply #7 on:** March 10, 2010, 02:55:04 PM »

1" is the goal as the base ring is 3.0" , gary

GGaskill · « **Reply #8 on:** March 10, 2010, 03:12:29 PM »

According to the drawing at work, an 1841 six pounder has 5.17" rimbases and 3.67" trunnions.

RocklockI · « **Reply #9 on:** March 10, 2010, 03:39:29 PM »

I'm sure that is true , but how much does the 1841 weight? About 850 ?

This is for sure one of a serries 1835' 38' 41' but the 38 it is no 41 .

It wieghts 681 lbs the proportions may be the same but it is a differant size gun . IMHO , as I havent found squat on the 38' anywhere .

First things first; thanks for cleaning up that huge wood dust and shavings mess on the lathe. 2nd, your pattern for the 1838 6 pdr. bronze gun looks very nice indeed, revealing a lot of careful design and turning. And I thank you sincerely for imparting to Mike and I a lot of knowledge about this and other related 6 pounders, as we had no idea they were that different in dimensions. I knew I loved the lines when we came across an 1841 at Fort Washington on the Potomac River and came across an Iron 6 pdr. Model 1836 in Lancaster, New Hampshire. You can see and compare them all at the following site: http://robinsonsbattery.org/ Someday we will see that M1838 in Presque Isle and that Maine Potato Grower guy again!!

Great looking gun, Gary,

Tracy and Mike

I'd have thought when the specification for this barrel was set out from the beginning .......not from drawings...and the recipient aka ..one Mr.Spuddy...is not just happy but somewhat excited about what he sees........then any comments about what the barrel basher...a certain Muskrat...has produced are irrelevant. Other than that for a "proven" bronze caster of some skill, his woodworking skills ain't too bad either. I'm working to photographs......incorrect and incomplete drawings just now and know just what the Colorado rodent was facing........and he has nothing less than my respect for his work.

carronader · « **Reply #12 on:** March 12, 2010, 02:31:43 AM »

I would like to see what kinda job you made of this 1838 though Muskrat..........can't have you barrel bashers thinking timber trimming is kid's stuff. and..........using metal lathe is cheating.

Gary,

Your model came out great, I am looking forward to seeing the end product.

Carronader,

Where is that Unicorn located? Sebastopol?

gulfcoastblackpowder · « **Reply #14 on:** March 12, 2010, 04:16:03 AM »

I agree that the trunnions look a little big, but overall it looks really good. It'll be nice when the weather is better suited for casting. You're going to go through a lot of bronze soon!

carronader · « **Reply #15 on:** March 12, 2010, 06:13:11 AM »

sure is kabar...........although dragon is training me (lost cause) is Sevastopol. Is a Russian guy's site... you want it ?

RocklockI · « **Reply #16 on:** March 12, 2010, 10:41:41 AM »

shorter and smaller in dia. these are the final truions .

Spuddy · « **Reply #17 on:** March 12, 2010, 11:33:16 AM »

I still like it!

GGaskill · « **Reply #18 on:** March 12, 2010, 11:41:59 AM »

These are the final trunnions.

Your call in any event.

What kind of wood is it?

RocklockI · « **Reply #20 on:** March 12, 2010, 11:54:25 AM »

I made the tube from ,laminated poplar the trunitions are oak .

carronader · « **Reply #21 on:** March 13, 2010, 02:08:14 AM »

As usual damn barrel bashers not thinking of the carriage...............not just Gary.......he can give me abuse anytime........too short trunnions means less room between trails or cheeks...because you want the ends of the trunnions to be flush with the outside of the trails / cheeks ...this can affect all kinds of dimensions... overall width of trunnions to overall width of carriage...hence... thickness of trail...possibly needing to reduce length of trail for proportion or strength..impacts on wheels for same reason........when building barrel for the eye and not specific to drawings or for museum

...this one detail can cause a lot of grief...and possibly only time I would say damn the drawings.......I don't think they had micrometers back then.

Double D · « **Reply #22 on:** March 13, 2010, 03:23:07 AM »

Carronader,

Determining length and diameter of trunnions is spelled out and defined in Muller. Length of trunnion defines thickness of cheeks according to him....

dan610324 · « **Reply #23 on:** March 13, 2010, 04:28:20 AM »

and the trunnions are most often of the same diameter as the bore
the length on the older cannons is between 1 and 1,2 calibers

carronader · « **Reply #24 on:** March 13, 2010, 04:46:58 AM »

I know Douglas..........just want metal manglers........easy life tube turners.........Duraglit eating ..Brasso drinking...ex marines to bear it in mind..........Swedes I already know don't worry about the wood guys.

Cannoneer · « **Reply #25 on:** March 13, 2010, 10:19:59 AM »

Gary,
You did a fine job on the wood pattern. I knew there were previous models which led to the famous M1841 6-pdr, but I never noticed these features before. I copied and enlarged the photo of the Fort Fairfield M1838 that you posted, and if you look closely you'll notice what appears to be an ogee molding in front of the breech ring making a transition from the reinforce to the breech ring, and the same thing can be seen in front of the trunnions where the reinforce transitions into the chase of the barrel. These features were evidently abandoned on the Model of 1841.

Boom J -

Thanx for posting the names of the various shapes. Some are very familiar, some new. I'll have to dig out the dictionary to learn their exact meanings.

(I assume they are woodworking/pattern-making terms.)

dan610324 · « **Reply #27 on:** March 13, 2010, 12:18:32 PM »

I believe that the names are spanish words for the different shapes

some more names and info , if you click on the black picture it will open in an larger size
dont know whats happened with that one
sorry if the quality aint the best , but this is the size they had when I found them on the net

I also got a file with some very very interesting reading but its way too large to post here so I dont know what to do with it
dd , any ideas ??

Cannoneer · « **Reply #28 on:** March 13, 2010, 12:34:38 PM »

Tim,
I think those are actually architectural terms that were adopted to describe the different types of mouldings used on cannon.

Dan; the words are probably derived from Latin and Italian.

I couldn't find any of them on the banned work list.
