|10/32 inch on one end and 3/8 on the other this allowed me to construct this coupling into the hinge joint|
MAKING CHOP SAW PARTS-- Emergency application only not a safe solution for parts construction. Do not try this at home.The purpose of this part of the blog is to show what could be done in an emergency and nothing more. Every part you will see below could have been made with hacksaws and files and a drill press but more time consuming. If our national sovereignty was ever threatened from within or from without then understanding how to misuse tools to make a fast product could be critical to national survival. Mentioned earlier a chop saw can seriously, maim, blind or kill. The blade is brittle and easily broken-- traveling at near bullet speed so a large chunk could do some serious damage.
|Lever connecting hole. The coupling was 3/8 inch on one end and the other end was 10/32 this allowed me to make the part without having to tap the threads for the hole where the 3/8 rod screwed in|
|File work finished the job|
|Scrap from another project|
|Grove cut by a chop saw close to the size of the future handle. When the cut was made the part was pressed sideways to the blade slowly expanding the width of the grove. The grove was finished with a file.|
|Note the size of the chop saw blade, there is very little left . I am thinning the part so as to eliminate some file work.|
|Note the rough condition of the part but a lot of metal was removed|
|Filing did not take long|
Another large scrap used to make the fulcrum in the photo above. Note the change in the color of the steel from the heat from the chop saw. In my book I disuse the colors and changes necessary to harden metal to make emergency gun parts (or the whole gun). Though this piece of metal did not go through the whole process necessary to harden the part it is an excellent example of what you would be looking for during some of the color changes. Purple in the upper left hand corner makes things chisel hard and straw yellow to the bottom right removes the brittle nature of the metal after hardening.

|A hand grinder rounder the corners, Note the small size of the worn out chop saw blade . It would be to dangerous to use a full sized blade|
