I wanted the dashboard hinge like 4-5 years ago but the wait time was way to long so I made a plywood hinge out of desperation and it worked so good I never ordered the dashboard hinge. I used a pin locator at the other end just to make sure everything stayed square. The cost of material these days one bad cut can cost you hundreds of dollars...
Sometimes the best tool is not the one you buy but the one you build yourself. I also added a stop block at the end of the rail later on to make sure the rail flip back to its squared location everytime.
I am currently looking to build my own hinge, since i have a mft table but no table saw. I still struggle to make square repeatable cuts. Your video gave me great inspiration. Thank you. Also i saw you have both the track and the table saw. Something i am debating avout for a long while. Do you use both frequently?
I use a table saw much more often than a track saw. In my opinion a table saw is the most important tool in a shop as it cuts accurately and efficiently. You can build numerous jigs for a table saw to achieve all kinds of cuts whereas the use of a track saw is somehow limited to breaking up large sheet goods and producing tear out free cut on veneered plywood.
The rail hinge is pretty strong and has almost no play after its setup. The rail will typically go back to its squared position after being flipped and put back in. To be safe I also added a stop block at the end of the rail as you can see at 7:54 of the video.
