Alum versus Tap versus Corningware
On a thread a while back someone asked how to remove a broken tap.
There were a lot of good answers but one that I researched and wanted to try was the use of Alum.
Well to tell the story, it worked!!
But now I have a new problem. 
I was working in some aluminum and got in to much of a hurry in tapping for 8-32. As luck would have it, I broke a tap.
Now what do I do?
Well I come to the frendly Home Shop Machinist mag web site and do a search and find someone posting about using Alum to eat away the tap.(And it does)
But they didn't say how long this was going to take. 
I didn't really time it, but it took probably at least 8hrs to cook this tap out of my prized project.
This still wasn't the reason I am posting this item. My problem now is, how do I get this Alum out of the Corningware I borrowed from my wife?
I am still trying, with no sucess yet, but me think that it would have been easier to have started the project over!!
