His recommendation is for a 1/12 scale model. Herb Adams, in his book “ Chassis Engineering” provides a whole chapter on chassis modeling using balsa and paper. Modeling a spaceframe chassis with balsa wood sticks enables you to see firsthand the differences triangulation makes to the stiffness of a chassis. Sometimes lowering the vehicle while using the same suspension pickup points will create poor handling. If the changes involve the suspension, such as lowering the vehicle, model the new suspension first.

Identifying the correct parts of the chassis structure to cut or modify is critical.Ĭonsider using scale models of the vehicle (if plastic models were made), to mockup the changes, or 3D modeling software to do the same. The structures formed by the manufacturer’s chassis designers have strong areas intended for loads and weak areas not intended to carry loads. When considering modifying a production-based chassis to mount alternate suspension, engines or drivetrain, spend time studying the unibody (newer vehicle) or ladder-frame (older vehicle) structures. In areas where tubing sees compression loads, a heavier gauge or larger diameter tubing may be better to use.Ĭhassis Design Tips (1/2) Modifying Production Chassis As tubing in tension provides higher strength than compression, a lighter gauge tubing may be used in tension loaded areas to save weight. The key aspect of spaceframe design is to identify and analyze the loads that are to be expected, and design the frame and triangulation to handle those loads in an optimized fashion.

Round tubing does not butt up against other round tubes well, and therefore requires a special tube notcher to cut round shapes into it. Square tube is easier to work with because cutting it involves straight cuts at a particular angle.

Spaceframes usually use square or round tubing. The diagram also shows suspension and other mounting brackets. Returning to diagram SF1, there are numerous examples in this diagram of how open box tube structures have been triangulated to create a much more rigid chassis. The force applied to the box compresses the cross-member, potentially buckling it if the force is sufficient.

Likewise, a wide variety of manual and automatic transmissions can be employed, including Powerglide, TH350, TH400 and 700R4 automatics, plus any 4-speed, Tremec TKO and T-56 6-speed, as well as Richmond 5 or 6-speed manual transmissions.Diagram SF4. Since most builders will want to have something more potent than the original 6-cylinder "stovebolt" engine, the chassis will also have motor mounts for the popular small block V8, or the new LS-series powerplants. A power rack & pinion (20:1 ratio) handles the steering.Įngine & Transmission Mounts For A Variet Of Applications Up front, Morrison's engineering team has developed a sophisticated Independent Front Suspension (IFS) that employs tubular steel control arms, adjustable coil-over shocks, a beefy sway bar and Wilwood front spindles. Morrison's engineering staff went about designing a front and rear suspension package that would deliver the handling and ride that has made the original GT-Sport chassis for Tri-5 Chevys the unquestioned industry leader.ĭesign Features Of GT Sport Chassis For 49-54 Chevrolet FRONT SUSPENSION

Little or no welding is required to install this chassis. All it takes is a specially engineered replacement chassis from Art Morrison and it's a project that most competent do-it yourselfers can accomplish in their own home garage.
