12-30-2010 06:59 PM Willys - Tilt Front Rib Install
With experience gained after the installing the first rib, the second one went along a little faster. Still, it took some time to locate the rib correctly. By using some spacers and a square, I made sure that both ribs were parallel to each other, which in turn will help the hinges work properly. The second photo shows both hinge ribs attached. Next to be installed are the center ribs, which angle out and follow the hood/fender line.
I decided to connect the two ribs together using bent plates and bolts. Three bolts are used on each side to connect the rib to the plate. This was more for looks than for strength. The third photo shows the plates before being bent to the correct angle.

Here are some photos showing the tabs being bonded in place. Panel Bond adhesive was applied to the back of the tab and to the corresponding area on the shell. It took a little practice in applying the adhesive to get the correct amount. I wanted a little squeeze-out around the edges of the tab so that I could trowel it smooth and create a fillet of epoxy around the edge of the tab. Plenty of guide lines, a square, and a laser line helped me locate the rib exactly where I wanted it. The last photo shows all four tabs bonded in place.

The front hinge rib is attached to the tilt shell with a total of four tabs on each side. The tabs will be bonded to the 'glass shell with 3M Panel Bond adhesive. I decided to try bonding two tabs to the shell at the same time, using the rib itself to keep everything in alignment. Once the first two tabs are in place, I can then bond the remaining tabs in place. The first photo shows the rib and two tabs attached, ready to be installed.
The second and third photos show the dry fit-up of the rib/tab assembly against the inside of the tilt shell. Because of the opposing slots in the rib and tab I will have plenty of slack in the bolt holes for final adjustment of the ribs once the tabs are bonded in place. The important thing is that all of the tabs for each rib are on the same plane. Alignment marks were made on the inside of the shell using a laser line to guide me in locating the rib correctly.

Here are the finished aluminum ribs made from the CAD drawings. They were laser cut out of ¼" aluminum plate and came out just as designed. There's just a mill finish on them right now, but I'll clean them up and give them a clear powder-coat before final assembly.
The next photo shows the mounting tabs for the ribs. These were made with 1 ½" x 1/8" thick aluminum tee stock. I made a few jigs for cutting and drilling, and it didn't take too long to turn these out. Each one is bent to fit a specific location on the tilt shell.
The third photo shows how the rib and tab are bolted together. The slots in the rib and the slots on the tab are at a 90 degree angle to each other which gives a lot of leeway for adjustment. The ribs are attached to tabs with ¼" bolts and stop nuts.

12-30-2010 06:47 PM Willys - Tilt Front Hinges
With the tilt hinge location verified, mounting brackets made out of 3"x2" angle were fabricated and bolted to the outside face of each frame rail. The frame holes were drilled and tapped, and hex nuts were welded to the bottom of the brackets. I opened up the hinge bracket holes and turned them into slots for horizontal adjustability. I will also be making up some aluminum shims to fit between the frame bracket and the hinge bracket for vertical adjustability.
The last photo shows the relationship between the hinge and the front rib, and how the hinge arms are bolted through the rib.
