Yes, it's the same repeated story of a broken tap but with a solution. A few days ago I was merrily tapping my AMD 65 rear trunion when I felt some grinding from my 10-32 tap. While trying to back off the tap, it snapped. Of course this was the last hole I needed to tap. After reading on various websites of similar stories of broken taps I tried to break it up with a hammer and punch. All I accomplished was to mess up the treads. Then I started searching broken taps on the web and came upon a device called Walton tap extractor. I ordered the #10-3 flute extractor from Brownells with extra fingers. The extractor cost $8.50 and the extra fingers $6.30. After it arrived today, I was able to pull out the broken tap in about ten minutes. It took so long because I screwed up the treads trying to break up the tap. The moral of the story is to use the right tool for the job. Now I'm off to finish my AMD 65.

That's cool! I too have a broken tap in the rear trunion of an AMD63 kit.
My Dad the ole' machinist says I need to order some real 2 flute taps from a machine tool company and forget those 3-4 flute hardware store ones.

I agree with the 2-flute taps...keep them cleaned out, and they'll work alot better than the others. as for removing, that tool works great. trick is.. use lots of lube (I like a stick-type tap lube, kind of looks like a deoderant stick, only round, and waxy, less mess, and about the best i've used, called Accu-Lube) and 1/2 turn in, 1/4 turn out. this will break off the ribbons of metal and keep them from running ahead of the tap and pinching it.

Marge had here bad things, but the woman gave a fortune to childrens charities She left a ton of money to childrens charities too.
She was rough, but her heart was in the right place.
Your right! Cincy was the machine tool capital of the world at one time. There is even a display with machine tools in our history museum.
