Re: inside milling attachment

Ian,

That would be my vote as well. Don Lancaster has a source on his site
at: http://www.tinaja.com

About 30 bucks, last time I checked... dental burrs are held by
friction.

He wrote about it in one of his old "Hardware Hacker" or "Resource

research before asking, but his phone number is posted on his site,
and as long as you're "to the point", I find him friendly to speak
with.
