I take great pleasure studying and analyzing old file photos, sketches, illustrations etc. of all the different models of the S30 in the production, testing, shipping, or just new and still in the unmolested state, when I come across them, as I know many others on this board do. For the purpose of discussion I didn’t know where to put this, thus the new thread. I would like to hear the thoughts of others, to help us better understand. Recently 26thZ (Chris) posted some very interesting photos & sketches that warrant some careful study. Some of them seem to create more questions than answers. I am going to touch on a few of these, and would love to hear other opinions. First up: This sketch captured my imagination for a number of reasons. Keep in mind this is only opinion and may not stand up in court. The first thing I noticed is, this sketch was depicting an offline metal shop repair station. The body/shell is suspended by an electric powered hoist which is used to lift the body/shell out of sequence, off of the assembly line and place it into a metal repair stall. It is situated over a large safety stand. There is a control box for the hoist shown with 4 buttons on it. Up, down, forward & back. The hoist control box cable is suspended on a balancer, so you can reach up and easily pull it down to waist level to operate. A few different capacity welding gas bottles are shown. From my inspection of the wire welds on my Z, I would venture the guess that CO2 was used, and not an argon mix. It creates a harder weld with less flexibility. Can’t tell what is on the floor on the right. OK, this is what I think I know. Now, for what I am puzzled by. In the sketch the front frame rails are not shown. Do you suppose this can be written off as artistic license, given the style of the sketch or do you think at this point in the build, when the body/shell was taken out of sequence, off the line, the front frame rails and all other pieces forward of the cowl, actually have not been added yet? I’m trying to guess where the lifting balance point would be without anything yet fastened ahead of the cowl. I have an opinion on this, but no evidence to support it. Next up, is the controversial question of the factory roll bar mounting points that are present on all cars, even if a roll bar was not called for. Some believe these mounting points must have had another purpose, possibly being used as an assembly aid or frame-up set point. On first look at this sketch, I thought…ahh!...looks like a spreader bar mounted to this location, but I’m not convinced. Could this just be the luggage riser depicted or..? I look forward to your best guesses even if they are more “off the wall†than mine. I’m sorry but I don’t know who to credit for the photo.
