Hello, I am working on a Crosman 114. The compression chamber filling head at the front is threaded in with (I believe 21/32 x 32 thread count). Tried 5/8 x 32 it's too small. tried 11/16 x 32 it's too big. The problem is the threads inside the barrel are brass and flattened, so I can't get a bite on it to thread it in. How can I chase/clean up those threads. Cant find any taps or thread chasers that size. Any help or advice would be greatly appreciated.
Thanks
Hello, There's a tap that size but, it's on the expensive side. Below is a link.

Hello Shooter, I saw this on e bay yes it is a little pricey. And not sure what the xGH3 means the picture is definitely not a 32 thread count. Had someone say he can make a tap for me but it would cost $230. That's not happening, LOL I will figure a way to clean them up.
Thank you for responding have a great day
If you have a steel screw of the correct thread, you can turn it into a light duty tap by filing cutting slots into it. Reducing the leading diameter (resemblance to a plug tap) would help help. Going further you can case harden it with case hardening compound to make it more durable.
The thread may be metric.
