Dang, that is a bit out of my price range I can't justify spending 140 bucks on a toroid (and I do realize it's not a bad price, at all). Oh well, thanks anyway.

yikes! out of my price range, at least right now they are.
Oh come on you wusses! That's just a couple of hours' work, wash some cars or something! Polished copper AND seamless-soldered together, you can't beat that.
Daniel, I'll do two little ones for $50 if you can ship to Australia (for extra, of course). If you'd prefer a USA shipping address, I can organize that too.

True they are awesome, I only meant right now is a bad time.
I still want at least 2 of each but I'll have to wait till after I pay my INSANELY HUGE AND BLOATED MORGAGE! Ebay has drained my account this month. I have plans for a big coil.
Daniel,
If you can save two of each size for me for next month and can ship to the US that would be awesome. I don't wanna miss out.

Don't misunderstand the reasons behind my questions about your toroid fabrication process; I'm not a potential "competitor"! As an Engineer, I just like to understand the "details" of how something is made, especially when it comes out as nice as your toroids did. I'm familiar with industrial spinning processes, both manual & CNC, but just like laying down a visually perfect weld bead, manual spinning is part technology and part art. I'm surprised at how well your plain-ended "forming stick" worked, as many commercial forming tools use rollers at the end to prevent wrinkling or rippling the surface of the workpiece.

I received mine today, and I can only say, the pictures don't do them justice. 140 dollars might sound like a lot, but if you see them in person you'll understand. They are totally worth it.
