The topic I started about the built-in Halon fire extinguishers has made me aware of some interesting points both about Halon and about people jumping to conclusions. The most informative and CORRECT e-mails were sent to me off-list. The reason? These people have had their feelings hurt for giving their opinions and advice on the DML before and don't want to be torn up anymore. Toby picked up on this really well concerning Jim's question about rebuilding the master cylinder. The first post that I did concerning vacuum bleeding the brakes wasn't allowed through by the moderator because he felt that I gave bad advice telling people that I dressed the bleed screws threads with teflon. But had he realized that this is a readily available product in automotive stores sold specifically for dressing brake bleed screws then maybe he would have let it through. Then when I ask about installing a built-in Halon system, my post gets an ill-informed disclaimer built into it. I'm not complaining about the moderators in particular, but these instances are the first to come to mind because I like freedom of speech -- which also implies freedom to give bad advice or ask stupid questions. Whatever happens, we still end up taking the good with the bad. I would rather weed through off-topic spam than have genuine good DeLorean talk get censored out. About Halon: I've learned that this stuff is very safe and effective. It is used a lot in airplanes and even in the space shuttles. It does NOT displace oxygen. Except for environmental regulations, there are no problems with using it in an automobile -- even in a confined passenger compartment. How did I learn this stuff? From e-mails off list that directed me to various web sites. Now you say, "You saw it on the internet, so it must be true." No, I don't mean this. I read a few articles written by the EPA and some companies selling the stuff. Except for the environmental regulations, it is a damn good idea to have Halon in your car. I'm still looking into it but am turned off by the legalities. Halon is no longer manufactured in the US, and the replacemnt for it will be phased out in the future also for environmental reasons. Maybe by then they will have a a better substitue for it, but I'm not anxious to install a system in my car and not be able to keep it charged. I've had small Halon extinguishers before and had to throw them all away because they leaked and I couldn't get them refilled! The Halon they contained was identical to R-12, and this stuff is difficult to keep bottled up. I've had a few cans of R-12 go empty on their own, too. The next time I find myself at a marine supply house, I'm going to see what Halon systems they have for sale. I don't believe that CFC's really do anything to the ozone layer anyway. Coincidently all this regulation crap came about at the same time that the patent on Freon expired. As far as over-moderation goes, it was really interesting to meet some of the moderators in Memphis. They all treated me with kid-gloves. But it's no wonder. Y'all don't get to see my messages that they don't let through. Once I had a few beers too many and started a post calling them all a bunch of "twisted bastards". The results were really interesting. Some of them showed genuine concern for my feelings while others just categorically threatened to ban me from the list. Well, none of us are perfect. But it really disturbs me when otherwise well written on-topic posts seem to just disappear with no explaination. Will they ever make me a moderator? Not a chance! :-) My next post is going to be a re-run of a very on topic humorous post that presumeably never made it past the moderators. If you enjoy reading my "column" and don't see this one posted, then e-mail me off list and I'll forward it directly to you. It's a true story and a laugh riot. Walt Tampa, FL
