I see that there is a couple of types of hinges out there. one that mounts INTO the bumper and a surface mount type. Given that I will be needing the carrier to mount to the rear of the framework, I believe a surface-mount is the way to go.
Here is a pic of a surface mount that uses roller bearings instead of brass bushings.
I figure I can build this so this piece is mounted to the frame build out and sticking through the rear of the bumper just at the seam of the center piece of the bumper and the passenger end cap of the bumper. This should give me the clearence I need to swing the carrier out and be able to open the rear hatch.
So I have some questions as to metal thickness. When I go to make a mounting point on the frame for this hinge, is "c" channel acceptable? Should it be boxed completely? What thickness steel should I use as the frame mount point?
As for the carrier itself, I believe I will be using square tubing. What is recommended for this? 33" tire plus a couple of Jerry cans is my plan as far as weight goes.
I do not know what type of latch to use...I see several out there, some look bulky, I would like something that has a clean look. I also want the carrier to lock into an open position so it doesn't get in the way when the rear hatch is open.
Lots of design ideas to hash over.
I know, search is my friend
