Well, take two steps back. I did not see the bind of the hood frame against the fender until I attempted to raise the frame for the first time. The photographs, though, tell the story. Now, it's back to the design phase. I've been able to work on a design that uses two fixed pivot points rather than only one. this design should keep the hood frame in the same position, relative to the fender, in both the horizontal and vertical position.
Picked up on the hood hinges again. Decided to weld nuts to the hood frame and fasten with stainless steel bolts when the time comes rather than welding the bolts to the frame and using SS nuts. Tapered the angle iron braces that will attach to the frame, cut elongated holes to align with the welded nuts, and temporarily bolted the braces to the frame. Everything still lines up pretty well. Next step - weld the braces to the hinges.
Tacked the hood hinges under the hood sides. Welder son suggested I use a rod through both pivot points to make sure they sat square (my mother says the inheritance of my dad's mechanical and fabrications skills skipped a generation - thanks, son!)
Clamped the brackets that will bolt to the hood frame and let them swing vertical to check that they stay equidistant when swinging up and down - so far, so good.
Continued fabrication of the hood hinge, getting the spring attached to the two parts of the hinge. It's good to see the hinge operate as intended. The design will allow the hinge to be hidden within behind the liner of the engine compartment. The long vertical piece in the third and fourth photos will attach to the hood frame.
After three months of thinking about it, I finally started the welder and began fabricating the hood hinge. The thought behind the hinge has always to hide the spring and the tilt mechanism. I think I've finally got a design that will accomplish to objective. These photos show the pivot point of the passenger side. More to come, now that I have a clear path.
