I tore up an old towel in about 3/8" strips and sewed the pc end to end until I had enough to wrap round the barrel in a spiral leaving a little gap between.
Kept soaking with full strength outdoor type chlorox (thats just what I happen to have). I let the metal get dry but not the rag wrap.
Oh, also when wrapping I kept twisting so it was not flat all over.
And once at about four days or so, I happened to have a dead yard tractor battery and I took out enough acid with a big eye dropper and soaked the wrap just once, and in between.
Be sure yer out side when ya do this. It foams up real neat.
After one week, scrub er down with brillo and a bucket of hot water, hard. It will take it.
Then rubbed with 0000 steel wool and motor oil.
It is the first one I ever did.
As for the complete rifle, you'll notice I didnt show any close ups!!
I just cannot see like I did. But I never was a real builder like these guys today.
But I sort of imagine my guns are allot like the old ones. Lots of little misques, but function and shoot well.
And put the meat on the table
Adios
