Summary

There is a porter cable tool on the market, but I wanted to improve that tool:

First, with 3d printed template, it's so cheap I can print 3 and fix them together with a piece of wood to have perfect spacing between hinges.

But the original tool is fixed to the door with nails or screw and it leaves ugly holes. so I wanted it to be fixed to the door with a clamp system.

This clam can be fixed on the door or on the door frame.

It uses 1/4-20 bolts and nuts.

Here is the router bit you'll need
