Liberty Training Rifle - Trigger group

[Sprocket]

Hi All,
I've got the gun and want to work over the trigger group - stone the hammer & slide release.

I haven't torn one down and would like help with the disassemble, machining, reassemble work.

I can provide the parts and coffee, willing to travel.

I'm pretty good with mechanics but tend to be a bit heavy handed so the delicate work can really frustrate me at times.

Thanks
