[modeleng] Re: Broken taps

1. Throw the alum out the window
2. Go to your local tool and die shop or mouldmaker and have them EDM out
the tap. Fast clean and no risk.

Make sure they know what it is you're working on and that you are flexible
as to when they can do it, and the charge will likely be small if any.
