I don't have the exact theory handy, but, it is valid. (you could ask Larry Lipman on Rec.Autos.Tech) I believe it has to do with the overall polarity of the car, and its interaction with pos. and neg. Ions and other particles. Many cars *used* to have pos. ground, but most all production changed over by the mid-60's. Neg. ground doesn't eliminate reaction, but reduces it, especially in electrolytic enviroments like the salty N.E. winters. ...does anyone have any Bentley's Spridget manuals around for sale? Moss Motors. "the Complete Official Sprite/Midget", I cannot remember who That should be the Bentley. :-) Wade Nivison, MA has for sale: Sprite MkII Workshop Manual (AKD1834) @ $100. That's How much I paid for my Sprite- and it came with that book. Mayby the car was free? ed D. mumbles: Next time, just go on in there and keep muttering 'Whitworth' Anybody have a short disourse about fasteners? Sizes named by diameter of shaft: SAE (some acronoym about american "standards", which lists the various systems of pitch, hardness, etc.) ASF- American Standard Fine -Found on many British (and Japaneese) cars of the 60's. US measure, fine threads/in. ASC- American Standard Course -More often found on US cars, and easier to find in hardware stores. BSF- Similar diameters & thread pitch to ASF, but different thread profile. (different angle, more rounded) Found on older British Iron. Sizes named by size of *bolt head* Whitworth- He was one of the first to come up with a standard thread system. Used in England from ><~1875? and even in the US for a while. Used in random locations on British cars of all years until they went metric in the late 70's. Metric- just as bad as the rest- there may be *3* thread pitches for a given diameter, instead of just 2! There are/have been others, lesser used. And don't forget the pipe threads, (tapered). You think you have problems- My MG PA uses BSF, with some Whitworth thrown in. I have an ASF/C tap & die set, but still need to get BSF, Metric, AND Whitworth! ________ /___ _ \ Roger Garnett (garnett@tcgould.TN.CORNELL.EDU) /| || \ \ Agricultural Economics | The All New: | |___|| _ | 3 Warren Hall | South Lansing Centre For | | \ | | | Cornell University | Wayward Sports Cars \| \ |__/ / Ithaca, N.Y. 14853 | (607) 533-7735 \________/ (607) 255-2522 | SAFETY FAST!
