tinitus - Good advice on the magnets. The site lists them as having nearly 55 lbs of pulling force. I'm able to get them apart by sliding them apart and twisting the magnet so it is at a 90 degree angle to it's neighbor. Then I can pull them apart.

FYI, the ribbon is basically the same as my original prototype (attached) except the magnets are twice the thickness and the frame is also bigger stock.

BTW: I got my ferrite toroids today but I just found out the steel is back ordered so I don't know how much longer it will be. I won't be making much progress until it gets here.

Denis,

Did you ever get this driver up? How did it compare to your first effort?

ABJensen, i drew and paid a lathe to make it in a milling machine, it cost arround 80usd, and he gave me eight gears, and i distributes between some my friends that are making smaller ribbon tweeters, and i still got two spares!
It has square edges, but with a small knife i will scrape de nylon and round it.

They are facing each other. In other words all the magnets on one side (one bar) are facing the same way and that is towards the other bar of magnets.

As You can see, each bar holds 2 rows of magnets. These rows are just sitting side by side and facing the same way regarding magnet flux.
Otherwise it would not work too well. hehe
