The fan comes with a shroud that will seal real well around the edge of the radiator, but it didn't fit around the inlet and outlet pipes of the radiator. I was able to cut out the areas using a hole saw in the drill press to make a good fit around the radiator connections. I may have to trim a little more once the hoses go on.
Before going any further with the tilt front, I decided to locate and install the radiator and fan assembly. I wanted to make sure that the radiator mounting brackets would not interfere with the rest of the tilt-front hardware, and also make sure that the radiator would clear the tilt shell when closed. The radiator is a Griffin unit made to fit the Outlaw body & frame, with 2 rows of 1 ½" tubes. The fan is a Flex-A-Lite unit pulling 3300 cfm. I also picked up a radiator mounting kit made by Outlaw to fit the radiator.
Here's the finished rib mock-up, which will stiffen up the shell, mount the grille, attach the hinges and linear actuators, and look good at the same time. Next, the motor goes back in, the radiator gets mocked-up, and then the tilt shell goes back on to make sure the ribs don't interfere with anything.
Another reason for designing the ribs with AutoCAD is that I would have a computer file that could be sent to a fabricator to have the ribs cut out either by laser or water jet, instead of me buying the raw materials and cutting and shaping the ribs by hand. Before I did that, I wanted to make sure that the design would work, and also to see how it would look. I printed out the drawings, glued them to ¼" plywood, cut them out and fitted them into place. Although not shown here, there will be a gap between the tilt shell and the aluminum rib. The gap will allow space for the rib mounting tabs to be bonded and 'glassed to the shell.
Once I had the templates made, I laid them out on a 1" grid pattern and traced the curve onto the grid. From here, I measured the location of the curve along the horizontal and vertical axis every inch. This gave me the coordinates that I input into the AutoCAD software to create the curve. Once the curve was created, I added the details. The last picture is the completed rib in AutoCAD.
