Thread pitch/ tap and die size ?

[rraybo37]

Hello all !

I recently came into a Colt .38 Special Police Positive. Dirt cheap . Problem is it needs a good and thorough cleaning and rebluing.

When I disassembled the ejector ratchet from the stem, I had to drive it out with a punch(it was very stiff) when I did this I boogered up the threads on the stem.

My question is, does anyone know the proper thread size of the stem, so that i could order a tap and die ?
It is just enough that it will not screw back together and I would rather not try and force it.
Thanks in advance for any replies !

I do not know the thread pitch but I would try using a carefully ground and polished punch to restore the buggered portion of the threads. Chasing the threads bi;; remove some of the metal and at the least create a weaker joint.. A knife like blade can sometimes be used to push the damaged threads back into position at least on the external parts..

Thanks for the input, I have a friend looking for a tap and die ...........

If all else fails I will try it. I was also going to stop at the local Machine shops, maybe someone has some old dies there.

Is there some reason you cannot measure the diameter of the rod and put a thread gauge on the threads to tell you what they are?  Shouldn't take you more than 5 minutes.  Larry
