Balls are the easiest projectiles to cast and as a consequence are the perfect learning medium. But , ladle casting is more precise and will produce better conical bullets. There are a couple of reasons for this. 1. The pressure through the pour spout is always the same from the ladle resevoir . 2. The alloy dip is always from the center of the melt for most consistent heat and clean alloy, not just the bottom of the pot. 3. It is much easier to control slag and other impurities from getting into the casting. 4. You have more flexibility in the speed of the pour at the same pressure from the ladle resevoir. 5. Ladles don't drip like bottom pour spouts when they get a bit of dross in them.I bought a used Lee electric pot from a buddy for a good price and yesterday I tried casting some balls with it. I was expecting some minor issues and maybe a new learning curve when using it. Wellllllllll.......I found it was extremely easy to use, convenient, less messy, safer than using propane to heat a ladle, and on and on! When I went to sort out the finished balls, looking for wrinkles, bad casts, etc. I didn't find any! I found some balls with a little hole in the sprue, but I think that is remedied with better timing and better technique at the end of each pour. It's so much better than screwing around with a propane torch, and jockeying a mould and ladle in mid-air for a good pour. It's like going from a bicycle to an automobile. I'm impressed.
My curiosity has gotten the best of me. What is a fettling shed? To me, that would be a place where a crafter of custom hand planes plied his trade. Bullet casting equipment just seems a bit out of place in such a building.This is my ‘hot corner’ in the small fettling shed I built.
Thank you. I collect and restore old hand planes as an interest/hobby. I had only heard the term used in describing the fine tuning of the plane for performance. Learn something every day.

In 'old English' also used to mean make or mend something..
I also have a small bench/desk with a faux leather high back chair where, on warm days, all I fettle is a few zeds!
