I just used the Dremel term to describe a type of abrasive disk, because most people are familiar with Dremel tools. I believe that appropriate abrasive disks should be available. Maybe a steel or carbide disk with diamond coating. > The positional > accuracy needed to get a good form to the result is also a problem. > Involute form is easy as a hobbing action and generation is possible > but not for cycloidal form. It's too bad that hobbing is not an option for most people. It would be nice to have a hob machine, but it's hard to justify if you don't make gears every day. (Which came first, the gear hob machine or the gears to make the gear hob machine?) > On 6/13/08, Kirk Wallace <[EMAIL PROTECTED]> wrote: > > On Fri, 2008-06-13 at 09:40 +0100, Ian W.
