" The Rolling Chassis". This is the much anticipated milepost in any rolling project. Imagination can begin to fill in the rest of the missing parts and some glimpse of the finished cart can take shape if only in the mind. At this point all of those countless hours of late night toil begin to show some real accomplishment. Tedious fabrication and grinding of parts to fit begin to show the worth of their design. But this can also be a most tenuous juncture in the progress of any project. I would guess that for every completed project there are several hundred unfinished "Rolling Chassis" sitting in garages throughout the world that will never be touched again. The vision of what "could be" is easily substituted for the REAL thing. I could very easily back off now and lose interest in finishing this project. This is not the time to rest but rather a time to regroup and look at what remains to be done. So I have made a list of the things that must be finished. In my opinion there is not as much of a logical sequence or order in which to complete each task as there was in the beginning. Personal preference may have more substance than structural integrity. The following is a list of fabs that remain to be done but not necessarily in this order.
1. Finish Steering wheel and linkage.
2. Bench Seat
3. Secondary drive system and Brake.
4. Roll Cage.
5. Body Moldings.

Continuing from this point is kind of like trying to avoid the curse of the "Unfinished Rolling Chassis" so I am beginning right away on the framing for the bench seat. We start with the uprights from the chassis floor. One thing to note at this point is that the frame is now supported by the coil over shocks. In very broad terms this is what is refered to as "Sprung Weight." I have measured the distance from the the bottom of the frame to the ground at each corner and found a small difference in heights. This can be corrected by means of adjusting spring tension and suspension mounts. I prefer to wait until the final weight of all components including the engine are mounted before making these adjustments. I mention it at this point only because the rest of the body framing needs to be perpendicular to the floor frame in order to keep it square. Use of a level will make the uprights perpendicular to the earth but when you correct the ride level of the chassis it may look a little lopsided. So I am using two bodies from 2 "T squares" to help align the uprights perpendicular to the frame rails. I am not paying any attention to the bubble levels at this point because I know that the frame rails are flat. Besides I have the levels going the wrong direction to check the level.



Now we have an outline for the bench seat. I will begin sketching how to build the seat and connect it to the frame.
