At the risk of starting a controversy, about the door frame braces. . . I was concerned about that also in the beginning. . . So I carefully measured all the openings before lifting the chassis. . then I stretched .008 piano wire both laterally and diagonally across the body openings {side to side diagonally}. I secured the wire tightly to bolts for the seatbelts and door hinges so it was taught. . Then I lifted the chassis and watched which wires became tighter or looser. . . There was no perceptible change in any of the wires and all my pre lift measurements remained consistent. .
Also note the rotisserie has a lower steel rectangle beam tying the front to the rear, which has vertical gusset bracing. . . this turns the entire structure with the body into a rigid four sided box and helps prevent flexing also. . . Be assured, I was very careful and measured a whole bunch of times before I felt confident there was no flex. . . I guess this is what happens on a rust free, low mile body with no prior damage. . . I expected some change but didn't measure any. . . . And the proof was in the assembled body . . . . all the panels and doors aligned with door gaps even and all edges flush. . . . So this sort of makes me stop and think. . . the only place the frame can flex is between the door gaps. . and this is a full stripped shell. . . I guessing at around 800 pounds total and probably only around 100 pounds of that in the center floor section. . . . and what has more stress on bending the frame rails. . . ?? lifting a fully stripped chassis. . or some lively driving and throwing around a fully assembled car on a bumpy road. . . . . So if the argument is that you must have door braces to lift a bare chassis. . you'd think then you would also must have to install a braced roll cage to have a little driving fun. . . Plus it helped that this is an extremely low miles Southern California no rust car. . and I don't by any means suggest this can be done on other 914's without some careful planing and measurements. |
