BTW you can buy precision rollers off the shelf. What you do is buy
   a 20 inch
   diameter roller bearing and grind the outer race apart and remove
   the rollers.
   You now have hardened, precision and polished rollers enough for
   three or
   four traction drives.

BTW Paul,
The rollers on the Timken roller bearings are controlled to 50
millionths of an inch. .000050 inches. Good starting stock.

Yes it would be. And so cheap too.
I wonder how they do that? I'll have to ask my grinder.
