Upon the date 06:38 AM 10/27/99 -0700, Mike Ford said something like: "John B" <dylanb(a)sympatico.ca> had originally written: John, Hmmm, you want to know for sure, eh? 5k pounds distributed _evenly_ over the 20x20 area is 12.5 lbs/sq. ft. Well, that's not much. An average size fully loaded refrigerator provides at least twice the floor loading (figure ~250 lbs over ~10 sq. ft.) BUT the _total_ floor load capacity of the building's floor must be considered. Your apartment building is most likely designed as a residential structure and not a factory/office/commercial structure. Therefore the floor load specs are going to be minimum required to get the building built yet allow 'normal' floor loading from 'normal' household furnishings distributed somewhat evenly across the area. If the room is on an outside corner of the building or on two sides of columnar support within the building then there may be a chance a big load will not stress the floor/wall interface too much. The walls below the room are very likely not designed as supporting walls, just separating partitions, so don't consider them as any support. The 40 lbs/sq ft Steve lists is probably correct for your local building code in Canada, but check for sure. Do you know your building super or other high-level building maintenance person really, really well? If so, ask their opinion. You indicate you're picking up more minis from a plant in the US. Yet more loading will aggravate a problem already raised by the original 5k lbs. I feel Mike is correct suggesting the liability risk. Steve's building code information he gave in his msg is likely how your apartment building may have been constructed. I'm not at all trying to discourage you from preserving old hardware in your apt. It's just that you should know the possible risk of a floor structure that just might be too weak to handle over 5k pounds in a 400 sq ft area --plus, disclosure to the owner will help you keep possession of your home whether or not they approve. You see, if nothing is said to the super how do you explain it to them when he/she knocks on the door to investigate "a dangerous situation", or whatever, reported by someone who's seen/heard of all that weight in that room? A real serious question indeed. Get an apartment in the basement level where the floor pad directly contacts the earth :-) Regards, Chris -- -- Christian Fandt, Electronic/Electrical Historian Jamestown, NY USA cfandt(a)netsync.net Member of Antique Wireless Association URL: http://www.antiquewireless.org/
