Although we can't find the time to actually do any work on the mystery metal round we will use to make the postal shoot gun, when we saw Carronader's recent post, we thought an update was necessary.

Seacoast, forgive me for sticking my nose into Corporate affairs...........but don't you guys have a certain (owing to the weather )
under employed Bronze caster hanging around your shop.............drinking your coffee............scaring the customers..........who could be rummaging around in the offcuts / scrap bin digging out a 50 cal. tube.............and making a contribution to the defence of the honour and reputation of the Corporate Enterprise. just a thought.
DD some (most ) of those carriages in your photos show a high level of quality in design and build.........are they self builds ? or store bought Impressive !
And ! My pet subject.........in one photo ..........clearly shown...........the Beauty of a finely patinated Bronze barrel...........next to it............the horrendous """"""""""""""" BLING """"""""""""""""""" of a highly polished - totally ruined barrel................Brasso..........Marines...............Drinking...........For the use of.
Tom, The real reason we keep inviting him back is because he is so entertaining. No matter how hard you try, you just can't put him into a single category, except coffee drinker. His gold prospecting buddy, Bruce, also a sculptor, is the one who can be scary sometimes. I asked my grandson about the regular shop visitors just yesterday. He just turned three. I asked, "What do you think of Mike?" "NICE" "what about Gary?" He says, "I like him he's different." What about Bruce?" "He's SCARY." All in all, a very interesting survey. So Gary is right, I am the dumpster diver. I find 90% of the mystery metal for little fun cannons around here and I have been busy lately. Below are a few pieces I collected about 3 weeks ago.

I always bring a small file to the surplus metal yard. This "file the edge off test" can tell you a lot about these rusty rounds of steel. I would NEVER take one home which displays no rust. I have absolutely no interest in exotic alloys or stainless steel, all of which can cause you major heartburn unless you know Exactly what type they are. After you drag it home perform a standard spark test and then you will know what type of carbon steel you have. Check internet for spark testing tek and charts.

This 3.125"+ dia. round, 15 inches long, is my choice for a nice little 3/4" round ball gun for the postal shoot. It checks out as a 1010, 1018, 1020, 1026 or 1030 piece of low carbon steel. Way overbuilt, 35% over minimum wall to bore size standards, this little gun should be a lot of fun to build, and, if carefully reamed, accurate too.

I managed to find two of these for about $50 each (100 lbs. each). At 30" long, they will make perfect, low pressure howitzer tubes of the same 24 Pdr. Flank Howitzer type as the smaller ones. A 1/4 scale of the original 5.82" bore should put enough metal on target to throw up plumes of dust and make 500 or 600 yard shooting a lot of fun. Bye the way, we buy new 4150 ordnance steel for our customer guns, all of them.
