Re: [CAD_CAM_EDM_DRO] Machinable wax

I've been using blue (Freeman) machinable wax with great success. You can
machine a mold, and pour the resin right in, or you can machine a master and
copy it using RTV. It holds up very well to either one, and is
self-releasing. It's pretty fun to machine, as well.

You can see a few shots on this page on my site:

I hae not tried any other machinable waxes; the Freeman has performed well
in everything I've used it for.
