You Are Never Too Old To Screw Up!

I decided to take one of my older Krieger 13.5 twist barrels, chop the thread off, and rechamber it for my LV Farley.

I set it up, reamed the chamber, then turned the tenon, headspaced it, set the cone, and threaded it. When I was almost through with the thread, it dawned on me something wasn’t right.

I had just cut an 18 tpi instead of a 16.

Well cr-p. What to do.

I have a HV Neuvo that is an 18 tpi, so I turned the tenon back to the correct length and headspaced it for the Neuvo. I picked up the previous 18 tpi thread and established the correct 1.060 18 tpi all the way.. It has a gap in the tenon where the Farley thread relief was, but what the heck, everything else came out just right.

I will shoot it tomorrow and see how it does.

So, even someone like me that has been a Machinist for 55+ years can screw up.IMG_2116.jpegIMG_2118.jpegIMG_2118.jpegIMG_2119.jpeg

It does take a lot of focus when chambering and threading….. none of us are perfect.
When I was younger, back in the 70’s and worked as a carpenter my protege told me “the difference between a carpenter and a good carpenter was a good carpenter knew how to fix his mistakes”. I would say you did well..
 
I made a boo boo yesterday
First one should be a 3/8x20un but knob position for 27 is right next to 20 on a HLV

I’ve screwed up a barrel tenon as well not backing out before reversing creating an idiot thread.
