397282 2005-10-18 01:05:00 One question off topic... what sort of lubrication should I use on an auto garage door (the main parts, eg the mechanism rod); grease, oil or just crc type stuff?

Other question, does opening and closing it cause any significant power spike that would affect the computers in the house?

I've never had a house with one of these fancy things. A previous place where I rented a downstairs flat the owners had a lift and I'm pretty sure it led to some severe degredation in some of my PC's components.

Thx

397283 2005-10-18 01:25:00 Because it's a slow moving mechanism, grease would probably be best . CRC type" "compressed kerosene" is useless as a lubricant .

It might be a 1/4 HP motor, probably less . The starting current would be comparable to a washing machine's, or a freezer compressor starting up .

I doubt if a domestic lift would cause any problems . We had a computer terminal room (with some PCs and other computers) just alongside the lift shaft, on the top floor, so pretty close to the lift plant room . That had the full Ward-Leonard AC-DC motor generator stuff, and it didn't cause any computer problems . (Water coming through the concrete ceiling from the other plant room overhead was a problem sometimes :() .

397284 2005-10-18 01:41:00 Hmmmm....3 years in my house and I havent yet lubricated the garage door opener.,..


Probally should get a around to it, Mine runs off a chain, to lube it I would put on a rubber glovem grab a handful of grease then spead it along the length......

Or use a grease gun, but Ill probally just grab a grease cartridge, then I wont have anyone waking me in the early hours wanting their grease gun back.....

397286 2005-10-18 02:01:00 Never had any problems with power spikes in our household when operating the door opener.
As for lubrication, I have only done it once and used some motorcycle chain lubricant on the chain (in an aerosol can). This is thick lubricant and does not fall off the chain and onto the floor. Didn't lube the runners but if I did, I would use grease (I think that's what they use on commercial roller doors or tilt doors).

397287 2005-10-18 02:09:00 Modern electric motors are pretty clean and don't usually generate any "spikes" if they are well made and a reputable brand . Not knowing any NZ brands, I cannot think the gov't would allow anything to pass testing that wasn't safe and not an rf generator or had a heavy hysterisis spike to worry about .

We have "green plugs ( . sandiego . gov/development-services/homeownr/green . shtml" target="_blank">www . sandiego . gov) " here in the US that eliminate the spikes and the upper 20% (PEP values) or so of the sine wave from the electricity to remove such spikes, and since EMF/REMF ( . hammerzone . com/archives/science/Elec/basic4 . html" target="_blank">www . hammerzone . com) theories hold that the upper percentages of the sinewave are basically useless and just generate heat, they are mostly engineered out of modern motors world-wide . This switching of flux and flow are the real problems, right after the initial surge and resultant spike in the voltage .

You DO have sine wave ( . google . com/imgres?imgurl=http://csunix1 . lvc . edu/~snyder/sine . gif&imgrefurl=http://csunix1 . lvc . edu/~snyder/1ch5 . html&h=404&w=515&sz=6&tbnid=di-dSf-bZmcJ:&tbnh=100&tbnw=128&hl=en&start=18&prev=/images%3Fq%3Dsine%2Bwave%26svnum%3D50%26hl%3Den%26" target="_blank">images . google . com hs%3Dt8f%26lr%3D%26safe%3Doff%26client%3Dfirefox-a%26rls%3Dorg . mozilla:en-US:official_s%26sa%3DN) electricity . . right? Not DC . . right?

This is especially true for impulse/start and capacitor/start motors . I cannot vouch for centrifigal start/dual-fielded motors as even here in the US they don't exist any more .

Since I've muddied the water here, let me just say that your puter is probably spike-non-sensative and transient safe . . at least modern ones anyway . If in doubt, install a current purifier that comes in the form of a surge-protector ( . howstuffworks . com/surge-protector . htm" target="_blank">computer . howstuffworks . com) . Get the highest value you can afford, and be safe from almost everything but lightning and cat fur static .

I cannot speak of the lift question . . did your neighbor have a hoist ( . gregsmithequipment . com/catalog/index . php?cPath=33" target="_blank">www . gregsmithequipment . com) for working under cars in the house? "Lift' doesn't make any mental pictures for me here in the US .

Perhaps you meant "elevator ( . otis . com/otis/1,1352,CLI1_RES1,00 . html" target="_blank">www . otis . com)", the invention by Mr . Otis?

How long have you been waiting for an excuse to put a rubber glove on met? :D
