I have posted these pictures before I think but here they are again.
I made these 36" wheels. They do not have the "dish" they are supposed to have. I turned each end of the spokes on my lathe.

Hey Zulu,

Okay, now you've really pricked my curiosity, why should the wheels have a 6º dish on them? The only reason that I can come up with is to keep the hubs recessed so they don't snag on things.

Six degrees shouldn't be too hard to do with an eccentric center. You would need bigger stock though, and there would be more waste.

Tom,
As I understand it, the dish is to give maximum strength to the wheel when cornering.
Here is a drawing that shows how the wheel is dished. You can clearly see the angled ends. Also all the limber parts.

They have an Amish wheel shop about twentyfive miles from me and they have some very elaborate machines to make their wheel parts. Nothing is done "the old way" by the Amish.

Reference to ball was meant to be generic. I am familiar with other types, such as canister, grape, shell, chain, and bar shot. Last two would, of course have limited use on land.

Was not aware that they set up a cartridge-type load in advance. Would increase the rate of fire, that's for sure. Since little cannon fire back then was indirect, imagine they had standard charges.

NB George,
Here is a sample of round ball, sabot and powder bag.

Reduces two steps and increases the rate of fire, certainly. "Sabot" is a wooden shoe, just like in France, I guess. Whence the word sabotage.
