[Hornant]

Any ideas how to take the slop out of the cocking piece. Its loose on the firing pin and its affecting the trigger release.

Hornant, I think you have posted this question 3 times or so. I know I answered you once already and a couple others have given you instructions on how to repair also.

[Edward Horton]

At the top of the forum is the “Lee Enfield On-line Knowledge Libraries (Index of Articles)”, in this library it has three different Enfield maintenance manuals that cover the tightening of the cocking piece on the striker.

If you ask this question “again” a certain part of your anatomy will be place in a vice, the vice will be tightened (unpadded) and this certain part of your anatomy will be struck repeatedly with a ball peen hammer. The end result of this “maintenance” procedure will allow you to apply to sing in the Vienna Boys Choir.

4. To tighten striker in cocking-piece.—Take an unserviceable cocking-piece with the thread for the striker in good condition; split it with the slitting saw down the centre, tap with the plug tap No. 10, and harden and temper. Then screw in the loose striker until the rear end protrudes a little beyond the rear end of the cocking-piece, grip the cocking piece in the vice, and centre-punch the centre of the end of the striker, or otherwise expand the metal; then unscrew the striker and remove any burr or superfluous metal from the end.

Soft solder can be used too. It's less brutal than swaging the threads.

Might try thread builder, similar to lock tight its found at auto stores.
I've used it to repair a carbuetor gas line/filter inlet. Its lasted for going on twenty years with no problems and theres a fair amount of stress on those threads.

[Hornant]

A thread builder or soft solder will be the way to go. I will try that. Thanks for the positive input. Can anyone tell me what the thread is.

The easy way out is to simply replace the striker and cocking piece in one fell swoop. Doesn't cost much AND you don't muck w/ the "original" parts which can be safely lost in the spare parts drawer.

No.4 striker thread is ¼ BSF (British Standard Fine). Note that No.1 striker is 30 tpi - only obvious way to tell them apart.
