This is out of left field but could a materiel like cerrobend be used instead of wax to make moulds for casting bronze?  Cost aside.

sorry dd , didnt think about that when you asked me
I just thought about mixing it in the bronze
but to use instead of wax , well that might be possible

but it also depend on how the mold looks
you got to be sure that all of it easily can flow out when you heat the investment mold
if you have undercuts and so it will be a small amount left in the mold
thats a big no no

Since the stuff melts at 156 degrees F/69 C it should be pretty easy to get it all out.

its not always true , the temp is no problem here .
but the shape of the mold is
if you got a cavity inside the mold that is lower than the connection to the main barrel , as a dolphin for example .
then you get some residues left there , if its wax it will evaporate and burn so thats no problem .
but with a metal used instead of wax it will stay there
it got almost the same melting temp as wax , but wax got the advantage to evaporate and it starts burning by itself at approximately 250-260 degrees celsius, depending a little on what type of wax it is .

so everything depend on the shape of the mold if its useable or not
but the wax aint that expensive , and personally I recover most of it
all chps made when turning can also be remelted

I got several hundred pounds of candle stumps so I have enough for a lifetime or two  ;D
and more comming a couple of times each year
I got a friend working as a janitor at our church , so he brings me the stumps every time they change them  
its just to melt them and pick the wicks away and its ready to use

if you bend a very thin piece of sheetmetal to a tube and hold it togeter with tape you can get whatever diameter you need , or if you got a silicone mold its no problem at all .

got a lot of boxes like this all over the place  ;D

You got it Dan, water cut steel.  I am having this built for me as I do not have the tools or abilities necessary to accomplish this task.

I almost forgot this one ! ;D





This one was turned from a candle , it will be the last one as I now have some really nice machinable wax ! 8)
The wax was very crumbly out by then muzzle . I think it will polish up nice though .

It's an underlug howie and will have a chamber and a 1" bore .

It looks like the nave ends of the spokes are not in line but alternate left and right of center a little bit, kind of like the way a bicycle wheel's spokes are arranged only not so much.  In theory it would give the wheel resistance to side thrust although the small offset probably wouldn't help much if the gun was being towed behind a six horse team.

Staggered spokes, sometimes called off and on spokes, were fairly common in heavy duty wheels towards the end of the wooden wheel era. They added a bit more strength to the wheel. They were used a lot in artillery carriages, especially by the British. They are easily overlooked in pictures but you will find them pictured in most artillery books.

Civil War era artillery sling cart used for transporting large barrels.

RIP John. While on vacation July 4th 2013 in northern Wisconsin, he was ATVing with family and pulled ahead of everyone and took off at break-neck speed without a helmet. He lost control.....hit a tree....and the tree won.  He died instantly.

The one thing that you can almost always rely on research leading to, is more research.

Similar rigs were also commonly used for heavy logging but that’s the first set I’ve ever seen that had staggered spokes. I couldn’t find a reference to the one in this photo in the Union Ordnance Manual, and I wonder if this might be a logging skid (called “Big Wheels” in logging speak, for obvious reasons). It was pretty common for them to be that tall, sometimes more than ten feet high.
