Roxy: DIY 5mm JIS Screws Continued

Ok, the second attempt to cut these 5mm JIS screws.  This time using #12-28 socket cap screws.  Amazingly, the #12-28 pitch is almost exactly 0.9 to begin with.  The problem is just that the screw is much bigger than 5mm, so you have to remove a lot of material.

Turning it through the die was definitely work, and you can feel the metal cutting.  Was worried how well the die itself would hold up cutting the alloy.


The screw before cutting.  It's already 0.9 to start.

About halfway through and you can see how much material has to be removed.

Checking the pitch on the gauge.

Now I just have to TEST IT...
