Thermite is nasty stuff. A soda can full of it placed on the hood of a car and ignited will melt its way *through* the engine. When it hits the oil pan, things get really interesting. I presume you speak from personal experience? - Don Gillies San Diego, CA |

At $30+ for new chainring guards, a price of $20 per ring mod would be great. Shipping wouldn't be much. Any takers? Most chainrings are aluminum, not steel. Aluminum won't burn on a grindwheel and in fact trying that may be unsafe as aluminum or brass can load up on the wheel and cause catastrophic failure. (pieces of stone flying out from 1760 rpm). I have never seen that happen but it's mentioned in two machining texts. If you want to trim a chainring, try a file. It shouldn't take long. I'll gladly file your teeth away for $20!! -- Andrew Muzi www.yellowjersey.org Open every day since 1 April, 1971 |

Back in the days when oxy/acetylene wasn't readily available, they used it for butt welding e.g. railroad tracks in remote areas. -- John ) |
