I am working on the door pins, and the directions call for tapping two inches inside the locking pins with a 5/16-24 tap. My taps will not work, as they have about 7/8" threads then have a larger shank. I ordered Irwin taps on Amazon that showed a smaller shank, but the photo was of something else and when received they also have a large shank. I am still looking for a reasonably priced tap to do this with, I found one online for ~$70 but that seems excessive. Any advice? I called Cleveland and Avery but they do not have anything.

The 60 piece tap and die set from Harbor Freight has the smaller shank you are looking for:

Perfect, thanks. I had not thought about a cheap set would have less steel thus the small shank I need. Going by HF tonight.
