Im LittleChris. If you know me, you know I like to have fun. I like to build things. I like to push buttons, boundaries, and my abilities. Like everyone here, I have a lot of projects going all the time, one of them being the Night-Train. Thread 1: http://www.jalopyjournal.com/forum/showthread.php?t=223071 Thread 2: http://www.jalopyjournal.com/forum/showthread.php?t=226347 My latest development for it are the radius rods; Im excited to share them with you. During the adventure of building my Model-T, I came to a point of indecisiveness of what to do with the rear setup. I started with an open-drive banjo, but when the Hemi shined around, I decided it wasnt going to be strong enough. I picked up a 58-59 ford 9-inch with a perfect width and 3.56:1 gears. The wheels I finally decided on where made by Rally America, chrome reversed Buick outers on International centers wrapped with Hurst slicks. Coming up with all the right stuff I desire is taking time, but it sure is turning out to be worth it. The rear radius rods are a cars system of restraint and direction against an outburst of power. Much like a bike to a kid on a sugar high.. They both give direction and have tremendous potential. Radius rods position the rear axle, restrain it, and help direct the power. There are only a few different setups to choose from, and the number of available kits is limited. Ladder bars, trucker arms, and four-links are great functionally, but none seem to have the class that the good old 36 rods possess. After trying to come up with a way to possibly modify a pair of 36 bones, I didnt have the heart to cut a pair up so I decided to build my own. Now, without having ends forged and special tubing extruded, I couldnt exactly reproduce a 36 bone. My radius rod contains what I interpreted to be the best aspect; the simplistic & functional design of the stout forged ends that clench the bells, and the seamless tube affixing it to its anchor point. The first step was coming up with a design that involved the style of the originals and the functionality I was after. I needed them to able to hold onto a three-inch diameter axle housing effortlessly, and clear the frame where it kicks up, all while looking cool for you dames to fall head over heels for. I happened to have received an associates degree in mechanical design last spring so I used my drafting skills to draw out my vision. I took into account the geometry of my frame, axle, and the materials I had available to me. Once I had fully annotated prints of the components that make up my rods, I sent three of the complicated parts to a laser cutter. In about a week, I had parts back in hand at an affordable price. Now, sometimes when components are designed, they look better on paper; when I started getting the parts together, I noticed the main arm tubing was going to too big in diameter, so I had to take some material off of the bottom of the main-plates. I also drilled a bunch of holes in them to lighten them up. For the main arms, I used DOM tubing. I clamped them in a vertical mill and cut a slot length-wise in order for the main-plate to fit in them. I also cut the ends open in order to fold them in so they would flow into the main-plate. The next step was the fun part; welding and grinding. I tacked the main-plate in the tube, and then using a torch, I folded the ends in to meet the plate to seal the tube off. I welded it up and finished the welds. The mounting plates I had laser cut were then tacked on to each side of the main-plate. These plates bolt to the mating part that gets welded to the axle. Cool. I lined the holes up parallel to the rod by using a fancy laser light and the available edge of the table. Once one side was tacked on, I used the mounting holes to line up the second side, and tacked it on. The last two parts were simply bar-stock that I tacked on one end and heated up with a torch and bent around the arcs. Once everything was tacked together and lined up, I welded up the entire assembly, and finished the welds. This was done with a carbide burr bit, a fine grinding stone, and many hours of my time.
