I ordered up a tap, it’s impossible to fine the right one. The one I have coming is a .275 x 40 which I can work the .275 down some if needed. The range of .260 to .275 is not that much because they do not require that much pressure to hold the collets. The more I search I find out what more of my parts in my box go to. I like the shape it is starting to take. I’ll get some pictures soon.
Thanks for all.
