Concrete Cannon #11
« on: May 06, 2012, 09:28:44 AM »
This the 11th concrete cannon I made.  It is going to Canada.
These guns have been my most popular item.  They can go outside while my wooden guns can't and they are priced much less than my wooden guns because it takes much less time.
I sell them for $1200 plus crating and shipping.
Barrel #12 just came out of the mold three days ago.  Full scale 1841 six pounder.  weighs about 225 lbs.  Barrels are availible seperately.

Nice job as usual. Have you considered making these from fly ash concrete to reduce the weight and shipping cost?
Fly ash concrete is also much stronger for about the same price as regular.
Hoover Dam is made from it.

How much extra is grinding off the seam on the chase?

 Beautiful work!
 
 So $1200 is your price for the barrel + carriage? And you've only sold 12 of them?
 
 I'd imagine that many a small town, cemetary, etc. South of the Mason-Dixon Line that didn't want to pay for an original or iron repro would jump at a few for that price.
 
 I'd be mailing out glossy fliers to every municipality within 500 miles while dreaming about my new Bentley.  ;D

Soot,
I have not considered using anything but one part Portland and two parts sand.  I actually like the weight.  It helps in the "illusion of reality" and makes it harder to steal. ;)
 
George,
The seam bothers me too.  In some places, it's more of a dimple than something I could grind off.  I have tried working on it before and tend to just make it worse. :P :-\

Hey Zulu, I just realized, you're the only cannon builder here, that can walk out of the shop where they're casting a barrel, and at the same time start laying the foundation  for a bigger, better shop right next door. As always, it looks great!

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

Very very nice!

I assume you have trouble finishing because you have to let the molds sit and the piece set pretty hard before you separate.  Are you casting horizontal? Could you cast around a mandrel? Looks like you have a sleeve in the bore? Could you cast horizontal around the sleeve and simultaneously cast it so the sleeve was supported and able to rotate? If this was the case you could simply "throw" your cannon and smooth the parting lines. I would imagine using a length of PVC and a steal pipe "fence pole" would work as long as the pipe cap could bare the weight.  Even maybe using a vertical means of casting?

It really looks nice! Did you do anything special to reinforce around the trunnions? I would be a bit nervous one could crack off, but maybe they're stronger than I think.

I would think Bondo or something of that nature would handle divots well.  Maybe the mould needs repair.

James,
I cast vertically.  I let it sit in the mold for 7 days.
 
Jeff,
The barrel has two pieces of #3 rebar running full length and one piece of #3 running side to side into both trunnions.  That piece runs through the bore.
 
George,
I think any attempt of me using bondo would be a dismal failure.  I know my limitations. ;D

Looks awesome, since it's coming to Canada I hope there is a mix up and it ends up at my house  ;D
