Anchoring Machne tools to floor
--If you live in an earthquake zone you should take into
consideration the way the thing will fall. No matter how well you anchor it there's that to consider. Best thing is to position the machine so that the long axis will be the direction it's most likely to travel, to minimize the possibility of tipping. I've found that with milling machines it's best to leave them un-anchored and just let 'em "dance". I took some photos after the big quake of '82 (I think that's when it happened), showing how far my mill moved. Lathe was anchored in the way I describe and did just fine. -- "Steamboat Ed" Haas : Better an early adapter Hacking the Trailing Edge! : than an early adopter.. http://www.nmpproducts.com/intro.htm ---Decks a-wash in a sea of words--- |

I am in New Jersey (as are the machines), we are located in the Ramapo Valley about a mile due south of the NY/NJ border. Earthquakes are pretty rare here but they do happen. The most well known fault line in New Jersey is located very close to us... it is named the Ramapo Fault. It may not be the major fault line. In 15 years of living in this area I can't say that I have ever experienced one. Before moving to NJ I lived in Oakland, CA. I remember well the 1989 earthquake (aka Loma Prieta aka World Series) that really shook things up in the Bay area. At the time it hit I was at home. I lived just below the Mormon Temple in Oakland. Telephone poles were whipping around like fishing rods. I don't remember hearing reports of machine tools breaking loose... I think most people were at home (or at bars) because the World Series was just about to start. The news was dominated by the collapse of the upper deck of a section of the Bay Bridge and the collapse of the elevated freeway in West Oakland... and the fires in Presidio district of San Francisco. Perhaps you are in LA area. I seem to remember they had a big one ~1982, also, perhaps one in the mid 1990s. -DU-...etc... |

There was a mild earthquake in ny state about four years ago that was felt here in PA... I felt it about 6 am... At first I thought it was me until the glasses on the counter made some noise. It was somewhere in the saratoga area if i recall. http://archives.cnn.com/2002/US/04/2...ors/index.html John |
