Hi, I am interested in possibly purchasing a turned aluminum toroid, with dimensions as follows:
-center opening diameter: 8"
-outer diameter: 32"
-cross-section of a side: 10"
The center doesn't have to be perfect, and it doesn't have to be all that strong. The main thing is to be smooth, and reasonably priced.. I am mainly looking for a ballpark estimate of cost, if it is reasonable, I will provide any file format of the 3d model that you prefer.
here is a picture that has an aluminum toroid of the style I am looking for in it:

Hi Seanick,

How many units will you require, and what grade of Aluminum?

I really only need one but I could use as many as 4. I know it would take some setup time though, so if you find its easy to make a lot of them once the first one is done, let me know as I can probably find something to do with them.

for the specific grade, I don't know what the options are so whichever is the easiest to turn would probably be fine. it is not going to be under any load other than itself.
