I always demagnified mine to reduce radio interference. Then I put oposing polarities on every other ball in the bearing. If not for gravity it would spin on it's own.

I do the same with bottom end needles.... alternate polarity with each needle. Stops them from skidding...
 
Well…….

When I modify motors I don’t have to bother taking the bearings out since I use a burr of common polarity so that it transfers its charge to the aluminum, brass, chrome and any other non ferrous parts :blink: . The grindings/swarth/shavings eject themselves naturally from the exhaust port and stick neatly to a magnet I keep near the recycling bin (Its all about the convenience) in my garage since they are of common polarity. B)

very little cleanup and the dogs appreciate being able to traverse the garage without picking up swarth in their pads :rolleyes:

also....for some odd reason it always keeps my batterys charged :eek:

must be the flux created from charged particles flying by :)

I hate to sound like Jack O'Neil here but what ya doin at tha river there Kev?

A huge electromagenetic feild generator that a powerstation is needed,

Ya guys got a Stargate Heh? "Jafar Toe Kree"

Dats classified ya know :ph34r: :ph34r: :ph34r:
 
That one actually belongs to us all…….

It’s a degaussing facility for the long cruise Atlantic boats that pick up a strong magnetic charge from traveling 20k + miles though a viscous fluid. The steel plates from a ship take up a significant charge. :blink: The process of degaussing is by induction of a large current through cables that are hung around the circumference of the boat (boats as large as Nimitz class carriers).

The reinforcing steel inside the concrete structure is all stainless steel (NON-Ferrous) in order to keep from being ripped out of the concrete during the procedure B)

Have fun dudes :)

so is that what they do to the nucluar submarines to demagnify them so there isnt a "trail"? i live about 5 miles away from bangor subase

The primary reason for the degaussing (demagnetize) is to reduce the possibility for attracting underwater mines. They throw massive amounts of electricity through the hull changing polarity frequently to reduce the magnetic properties of the steel hulls. It was discovered during WW II as an anomaly and then researched. Every Navy and Coast Guard ship is degaussed periodically. Still a lot of crazies out there laying mines.
 
Well Gene, dat is kewl and dat is big and this is one of the funniest posts I have seen in a long time. However, I'm glad that the winter building season is comming on. This is a time of great information, new ideas and lots of questions. By the way, have you noticed that the RCBOATS forum is practically at a stand still. There was always some very great technical information over there but the posts have almost shut down. To my thinking, the biggest problem with RCboats is the lack of pictures. One picture can take care of a thousand questions.

I love Intlwaters!

Don :)
 
Hey Don,

Yep I'll second that ;) Havent been back to RCboats fer a long while, Was glad to see Norm posting here again too,

This is the hotbed for info and pics,

Gene :D

I find it odd that you would call that stupid. We degauss everything that has a bearing surface on it to make sure that nothing sticks to anything that is around anything that rotates. In fact it is grounds for a rejection or pick-up tag to make sure it gets done, on any steel part that has been magged. Figure it out people. Go out and spend 6 or 7 grand on a street engine and leave the crank, rods, or wrist pins with residual mag and see how long it lasts. Especially when the cam starts burnishing the lifters on break-in. It may not increase horsepower, but it will damn sure increase longevity.

By the way, BOTH of my CMB greenheads were left with residual mag when I got them. They got run through the degausser at the local machine shop before I ran them.

Smoking crack? Only those that think that checking for, or removing residual mag is a waste of time. Granted, this is not a 747, but, I do not wish to waste a brand new engine. I encourage all of you that think you may have a problem too buy a magnetometer and check. They are not overly expensive. Or, better yet! Call your local auto machine shop and ask if they can degauss it for you.

So all of you that think this is just hype, I encourage you to buy that new engine, fill it with some fine iron powder and see where it sticks! Good luck getting it all off without degaussing it though!

Why is it that you guys crucify people for asking questions?

This would explain why the Aussies have such fast boats and why the toilet water spins the Other way.   The non-magnetic Turd

Well this Aussie product appeared on one of my boats and it isn't magnetic, but it does look like a Turd. :D

Wow! This is true. Now that you put it that way it make perfect sense.
 
I don't think anybody was crucified. But as for the demag, I have seen some of the fastest engines in the world and raced with some of the best. Can't say they demag anything and I can't say they are popping motors, so why bother? Is the proof in the pudding?
 
Preston,

If you doubt what I say as being true pull the needles out of your CMB and see if they form a nice little train. Having built 1 or 2 performance engines I can say that residual mag is no man's friend. Both my engines were that way.

As for people being crucified, it happens often with all the little"lol" comments in places they do not belong. If someone asks a a question, just answer it without all the humor, and treat people with dignity that are asking the questions. Each person has a line of interests that they follow. Many do not follow mine or yours. This is, after all, a forum.

If you know the person or have conversed with them and know that they will take what you are saying as a joke or without malice by all means have fun. If you do not know them, treat them with respect and answer the question without the humor or sarcasm. I have seen outright attacks on this website while visiting friends. It happens quite often. I get them e-mailed to me on a weekly basis.

If you wish for boating to flourish, I suggest everyone monitor the smug replies and foster the goodwill needed to entice new membership. They are after all, the people that keep the manufacturers going and motivated to bring out revisions and new products. No one likes being belittled when trying to learn. An one cannot learn when discouraged to ask questions. The only stupid questions are the ones that go unasked.

A newbie shows up at the race course, help him. It is in YOUR best interest long term. Piss him off and turn him away, you have just manufactured one more person that will run around and tell everyone we are all a bunch of prehistoric "d&%#@" and will drive one more nail in the coffin. We are being pushed out of ponds because people do not want to enact noise regs. Our sites are being gobbled up by housing tracts and there are still those that do not get the picture.

It will not be long before the EPA is on us about oil pollution, noise pollution, and air pollution. Look at the home products market. EPA is imposing more strict laws every year. Keep showing up on the radar and we will be next. No more 2-stroke weedwackers after 2006 or 2007 if memory serves me correctly. We pollute as much or more than any single weed-eater. Remember, the person you just pissed off may work for the EPA or some other agency. Temper your responses and be responsible. I like doing my R/C hobbies.

Never before in history has the technology been so cheap or readily available, think about the long term health of our sport. Not our own egos.
 
"LOL" ;)

Boeing Portland, all of the stuff you have said is good stuff. But, if you read the original question as it is posted on the topic page, the "crack" stuff was first mentioned by the same person who asked the original question and started the whole discussion in the first place. :blink: i think the guys were just following along with the joke. :) :) :)
 
Lets see Boeing, Portland, = northwest= district 8. Oh wait a minute, I am from district 8. Is there something wrong with that? Oh thats right we limit noise and try to take care of our sites.
 
Ease up dude. As for me helping the sport flourish, I usually try to help by telling the guys what is BS and what isn't. Clay is right.

Like I said, the proof is in the pudding. Until I am getting smoked (HAHA - smoked) by a demagged motor then it's just a fairy tale.

----have another hit
:p
I am still trying to figure out why I need a CMB. I still have my fleet of Piccos. But that couldn't be true because they all blow-up. Right?

How would you know if you got smoked by a demaged engine? They don't change color or anything when the get demagnetized?

And what was I right about? I just commented because of the "must be from district 8" statement.
