Need Odd Ball Screws

[smokemjoe]

I tear down old sewing machinces. The small parts out of these all mostly gun screw threads. Had one machince that was made in England and was a different thread that fitted my Brit. Enfields.

Old adding machines are a gold mine also.

Old manual typewriters are a good source of gun thread screws.
Used to get trade in machines back in the late 60's.
Typewriters were smashed with a sledgehammer but screws weren't hurt!
Very dirty procedure however. Dust, dirt and old ink from ribbons.

The part that makes the shape of the letter on the paper after hitting the ribbon is lead.

I replaced all the Frame screws in my Replica Colts with a common sized Singer Sewing Machine screw. I picked up a bag full of the used screws at a repair shop.

Not sure of the exact contents of the alloy but I was suprised to find these are not cast. Instead a tiny billet is placed in a die and vibrated till it fills out and conforms to the shape. the vibration acts like thousands of hammer blows to surface harden the type.
