F-Type compression connector itallation tool. I bought some compression F-Type connecto, but didn't have the right special tool to itall them, so I designed and printed this. You'll need a vice (like in the video) or a G-Clamp to use it, the pieces are just to hold the connector in place. I've used it to make up 2 ends, and it's worked perfectly both times. If you don't do this often, you'll save youelf a few $ vs buy a tool (even a cheap one).
