Now retired ., still diving . Currently developing my long sought after dive resort. Buying LOTS of rock, earth , concrete and steel.

My brass monkey for hanging in the bar.

Here ya go Bright. By the way Happy New Year .

R.I.P. Georgey ..., Thanks for the memories.

The outer is 4 1/2" and the bore is 2.68 . I know what your thinking !!!! I cheated ..., well I do not cheat on metal ., thats how accidents happen ., it is very important to stick to the rules. ! Caliber Rule minimum. As you can see the Projo (Beer~Can) Sits at the bottom of the bore ., where there is a 1 1/4"Sub Chamber in the 4"Breach . Just so everyone knows ., The Coehorn design ., was invented by a Dutchman ., Baron Von Coehorn I believe in the 1640's thus being period correct thru WWI used in the European trench wars. What Coehorn really invented ., was this sub~chamber idea ., as it allowed thinner barrel walls ., with a meaty breach ., I.E. Civil War Mountain Howitzers for example ., these Howitzers were sub~chambered using Coehorn idea. The Idea was his way of creating a mortar 4 men could carry. One man on each corner could carry a 24lb mortar wherever it needed to be in battle. Much lighter. Look down my barrel ., I know its not a good photo .,but you can see the sub~chamber.

Old Hydraulic stuff is good steel. Could even be DOM ., I bet its buffed ., We used 660 Bronze

casketchris . Your 1 7/8 bore is a 1.875 caliber bore. If you divide that by 40 you'll get 0.046875. Now if you multiply this figure by 39 ., you'll come up with 1.828125 . If it were me I would have your ball mold made at 1.825 . This would allow you the correct ., 1/40'th windage ., for maximum propulsion while not having it so tight its a bomb. It should easily slide down the bore at this size . Also be sure to properly worm and wet mop / dry mop between rounds. This will keep your bore clear and clean so you maintain your correct 1/40'th windage ., as well as extinguishing any burning embers. Also you'll maintain a much better consistency with your shots. I am not sure about golf balls. I haven't got any golf ball caliber artillery. However I understand people love that size ., 25 balls for 5 bones at Wal~Mart. I believe a Golf~Ball bore is 1.68 therefore the proper bore would be 1.725 . You'll probably lose some gusto with that on a 1 7/8's bore and a golf ball. Remember to NEVER patch a ball to make up for this when using 1" or greater bores. Capt Thighbiter's Can and Concrete technique is a good way to go . It makes for a nice conical ., and usually at whatever bore size you have ., the concrete weighs a small amount less than the lead ball. ., Still giving outstanding performance while reducing a bit of pressure off the breach. I have a beer can mortar and I love it. Concrete and cans make damn good ammo. Yes guns change to cannons starting at 1". Good Luck Sir with your new acquisition . It is a fine piece of ordinance to be sure.

A thunder mug sounds good , and so does an old English 1/2 scale 12 pound mortar. Youll need to bore to 2.68 in order to fire cans filled with concrete. Then build a sub chambered breach plug 2.69 ., freeze the plug and heat the barrel to do a seat fit with interference. then lathe turn the design and build a propper trunnion bar with nice welds on the plug. Its possible you could do a rev Daniel King Howitzer No#2 That would be nice . ., To use tube for anything you'll really need to sleeve the inside or band the outside to meet the 1 caliber rule . For example ., sleve the dom inside with a 2.55 X 1.5 bore sleeve ., then you would have your 4 1/2 outside diameter and a 1 1/2 bore ., then you could turn out some 1/3 scale british 18 pounders ! Lots of good things can come from that stick of DOM. Good luck. HarborMaster

Complex drawer and or shelf system ., I like it.

I forgot to mention it is a beatiful scale model of a Rodman ........., Except Rodmans have no cascabel ., they simply had elevation notches aon the rear face of the breach.

To know the dimensions would help alot. What is the bore size ? What is the breach size ? Is it a casting ? You cannont control pourosity during a pour . Is it machined from billet (Solid Round Bar) ?

I tried to avoid to this thread for obvious reasons ....., but ., lets talk about this thing. Castings are weak and brittle ., Yes I have 6 castings and 10 machined barrels. I moved UP to machined after many years of study and learning ., You know when you first get something you cut corners cause you dont know., later you get wiser ? Yea ., me too. You find out about rules ., start reading about PSI testing., Alloys ., Powder tests ., bores ., ect ., (6) Heat / Cold Interferance fit and bolted into a mill pocket . Machined from superior metals to high tolerances. Just curious about these comments ? We are talking trunnions from a safety point? O.K. Then I must ask what good is your casted (Porous) trunnion when your breach isnt as thick as the bore is large on the most critical point? The high pressures built are at the breach not the trunnions mid-section ., and recoil is why they have wheels .., to ease recoil on the weapon. Amazing. This is directed for Mr. Thighbiter. Also sir if you would like to bring this topic up at GBO's Cannon forum where there are actual cannon makers your more than welcome to. After all you are a member there. This is directed at your Wild imports gun. I have one ., I wouldnt use mine at an event where people are present knowing what I know ( and Yes I do know Osvaldo)., so I have filled mine with concrete. I didnt crack on your 385 dollar greystar barrel you got from Tim ., that had a seemed 1/8' water pipe for a liner. I know Tim. Also i didnt crack on you when you tried to sell it to a board member for 900 bux ., but I am cracking now. Lets talk about this at the GBO cannon forum sir where it belongs . Since we are talking about castings., I am sure Mr. Hawkins knows about NSSA rules and I wont question his cannons ., But I will anyone elses. If your casting is not an original ., then it MUST be X-rayed ., do any of you have X-rays? If not youve got a lawn ornament. You wont be able to live fire at any sanctioned event . Of course you can pop it off at home and risk the lives of your loved ones or on some dock somewhere ., or a ren fair., But Nssa wont allow to risk the public at their event. Live Fire People ., Your talking about trunnions when youve had a greystar and a wild imports cannon ??????? Even the English Gun I am sure has no liner or X-Ray. Without an X-Ray YOU dont know ., neither does anyone else about the porosity of your casting. I have shared my cannons with board members. Please fellas shed some light on your credentials and your cannons., please let us see some photos of your toys? They did infact re-invent the wheel fellas. The pro's did ., Mr. parrot ., Captain Dalgren ., we've evolved to a machined gun over 100 years ago. Because metals became superior to out dated alloys. the U.S. military is the best ., and theyve re-invented the wheel. The Mighty mo was a MACHINED cannon firing a 2000 pound projo with 25lb bags of powder .,and your telling me not to trust a machined barrel. I respect you. but not here ., not on this thread and not with these statements. I am very grateful the navy didnt try to fire that projo with all that powder with a casted trunnion ..., what do you think ? Captain Jim I will start a thread on broken castings to demonstrate why NSSA wont allow them without propper machined breaches using DOM and X-RAYS . However Machined guns from solid round bar dont need lined or X-Rayed ...., I cant believe you guys dont know this stuff ., yet your commenting with some authority ?????.,Round bar thats about as solid as it gets.., They ARE a liner. Sorry for that rant but I found this thread to be filled with ignorance. Again please state your personal credentials on metalurgy ., cannon construction ., basic dimensional knowledge. And show us your proof of what you say .,pictures are good. Can we see your cannons? I can show mine and already have. There are formula for building ., there is a formula for Breach to bore ., bore to length unless howitzer or mortar (Even a mortar has a bore to length formula. And you got it ., there is trunnion to bore formula. I invite picures of broken machined cannon ., please expand on this phenomenon ., as I am going to start a thread on castings so others can see the importance of being safe ., perhaps it will help educate new cannoneers of safety ., no-kidding. If you guys already know everything please take no offense ., however if your not to proud hop on over to Greybeard outdoor and join the forum ., there is alot of guys there that are very involved in documenting whats in our inventory as well as saving them all over the country from Bronze disease. research ., creating ., and restoring. Theres alot to learn there. There are experts there . I learn from them and then I do what they tell me .,or I have it done or I go there to ask ., or I write a letter to Mr.Switlik for advice.. If anyone cares to pick up a copy the more complete cannoneer I believe Matt will be releasing his latest revision this spring. Matt Switliks "The more complete cannoneer"is a must read for anyone firing a black powder cannon.

Exactly Cast Trunnions are easily broken ., Klink ! Many cannons in parks around the country are missing cascabels . Cast Cannons varied greatly with the one inherant problem castors could not control even in the 21rst century . Porosity ! That is a big problem. This is why the NSSA has rules ., and why the cannon was improved over time. I have many examples perhaps I will start another thread. However here is something worth reading for all of you. Here is a story of a sucessful trunnion field repair.., that did infact take place in the field . Please enjoy this read. Broken trunnion story Out of period, but it seems to me that back when I was doing Rev War, that I read in the orders from General Howe, that the British troops sent out from Boston to take charge of any war material stored at Concord were instructed to "knock the trunnions from any cannons found", presumably using a large hammer. Seems reasonable to me. I would suspect that the technique had been fairly standard for quite some time. I really don't know how they could be blown off easily, but some well-place blows from a sledgehammer would do nicely, at least on the average field gun. >>>> Cascabel

I am sorry to learn of your misfortune and glad you are able to post Your ability to reflect with us is a testiment to your character and your tenacity. God Bless you sir ., get well soon. Any scarring will only add to your character

I'm currently working on a knife and belt sheath. Something I've wanted to do for a few years now. Patrick Hand posted a pic of a straight blade he made a few years ago showing a handle he pined with I think it was brass rod? Anyway I am trying my hand at fabricating a cannoneers knife using Patricks ideas and methods on the handle. The Cannoneers knife will have a brass blade ., since it dont spark.

I hope it works out ., those are an awesome chair !!!

I love that movie ., ánother wonderful story from Robert Louis Stevenson ., I got it on DVD about 5 years ago for my collection. Who ever hasnt seen it should ., its a fun movie and was under-rated.

Here you go .,it was alot easier thanI thought ., just google Obama Gun Bible Comment and you get a HUGE list.http://kingsrightsite.blogspot.com/2008/04/obama-calls-midwest-voters-gun-toting.html heres another http://www.suntimes.com/news/politics/obam...obama12.article and another http://radioactiveliberty.com/barack-obama...l-town-america/ Heres ABC's take on it http://abcnews.go.com/Politics/wireStory?id=4638366 I've supported every president weve ever had ., I always will even if I dont agree with them during the election. I think as an American I should stand for our president. I think people in our population give comfort to our enemies when they bash a president I will defend their right to do it as I am hating them. And any president loses my loyalty when he takes away my rights. That starts with the 1rst and 2nd amendments . Dont Tread On Me.

I will try to locate it for you ., it was during the primaries ., he didnt use the word freak ., however it was refering to people in Pennsylvania with hand-guns and religeous beliefs. He did apologize for it. He said he mis-spoke ., all politicians say they mis-speak ., If I mis-speak they call it something else. It was on the news ., it was something he said on his plane and a reporter caught it on tape and leaked it ., I do not know that i can find it in print ..., I will look for it I guess we are held accountable for what we say ., unless you are a politician ? My original post on this topic wasnt to offend ., I am sorry if I mis-spoke . . None of my posts are geared at anyone. I think sometimes we all get frustrated ., sometimes its nice to vent to our online friends and personally I learn from the inter-action. I do in fact have much to learn. My original post was to say I have found this sort of topic in other forums (Topic apparently about PC or Hollywood) thats all I meant to say. I am sort of confused as too how PC or Hollywood even came up tho since it isnt even in the thread title. I'll see if I can bring this to the thread title. I think Captain Sterling has a valid point. The title being So I guess I will address the topic. What I dislike the most ? Which is no matter what you wear PC or Hollywood. It is the way in which one speaks. I can observe someone in PC clothing or Hollywood clothing and yet they try to portray themselves with an extremely poor English or Irish accents . I find this completely ridiculous and absurd. I grew up in LA try to imagine if you will a Mexican American with a heavy Spanish accent trying to sound Irish ? I was born in America on the west coast and there isnt anything I can do to sound English (some on the east coast I must admit sound pretty good) . To speak PC correct English with correct accent and be able to put it together correctly (in the right context) ., as opposed to a few people running around tossing movie quotes. I feel Pirates were GLOBAL (After all Magellan had accomplished his feat 179 years earlier) and in 1700 their were Pirates in China., but no one goes around trying to sound like a Chinese pirate . If they did everyone would think they are messed up? But there was Chinese pirates. For me the phony accent is the part that gets me the most ......, there I said it . This gets me more than Hot-Topic or a pair of Bucket Boots. I think people should sound the way they actually are ... A pirate or any other citizen back in this day we are refering to ..., they acted the way they were ! So why do so many think they have to sound phony to get with the program? When was they last time anyone saw a Dutch re-enactor speaking Dutch ? or a Spaniard speaking the Kings tongue ? Now that sounds PC to me. If it sounds phony it takes from whatever you are wearing ., It ruins it for me. This is pretty much why I stick to myself ., try be myself ., do my own thing ., my way ., because ., in my mind ., at least I am being me. No I dont attend events. We dress for ourselves and enjoy it for the day ., We fire cannons and flinters Scuba Dive and have fun ...., I guess everyone is entitled to do as they please . I hope everyone has fun .,do as they please ., and stays safe.

I enjoy a few other interests besides this one . Scuba Diving is definitely my favorite then scale cannoneering and finally SASS (Single Action Shooting Society). SASS is alot of fun ., however bad tempers arent permitted at events ., You have to remember most of us are as Barrack Obama called us Gun Carrying Bible freaks ? Well needless to say a loaded weapon 2nd amendment rights and a concealed weapons permit demand responsability and cool temperment. A .45 Long Colt or a 12 guage should never get into an arguement. Here is an copy and paste from from a SASS forum . This is sort of along the same issue ..., I am posting this so that you can all see that., Playing Pirate is not the only enviroment you can be involved in that has its share of arguements. The more I am around people .., The more I enjoy Scuba Diving and Spear-Fishing ., The Locker is more peaceful than Legend describes it. I cant hear any bitching when I am down in the locker mate. Its a true peaceful bliss in the octopus's garden...., Until TWANGO !!!! Spearing into a tuna ., and the fight is on !!! Its just me and Dinner Baby !!!

Me too ! Its got a place in our office already.

Merry Christmas Pirates ., yer all deserved ., heres hopin' you-all git watcher after. May the New Year ring in yer favor
