DT, I was actually reffering to Rally Soap box racing Vs. AA local Racing. in one you travel around against the toughest drivers collecting points based on how you finish and in the other you win one race and go to the world championships. I am sorry to offend you if I did, but there is definetly a bad mentality towards younger racers.

oh yeah, speedboarding is harder cause you have to travel around the world collecting points to be competitive. :)

I am gone for a few days and a debate breaks out. first off debates are good as long as people dont start making fun of other people for their beliefs. if someone is tired of it than dont join in or reply.
Re: Have you ever tried running them dry?!? NO. Doesn't make assumptions unless you know what you are talking about. I have done alot of research on this subject along with older, more knowledgeble folks. Thats why all of you old schoolers are hated by many people. You just assume that us Yungins don't know anything. Well we do. We can find out about anything we want, and it is you old guys that we try to learn from and then we get a bunch of crap from you whenwe try to put in our 2 cents
>Doobie try practicing what you preach. You made a worse assumption then i did. Yes i have run them dry. and by the way, i am only 20, i have been skating for just under a year. and have had 2 races now. the people who teach me are Gary Hardwick who is ranked #1 in the world and Jarret Ewanek who is probally the most knowledgeable and experieced racer in any type of gravity racing. He is an aerodynamic enginer (is that even spelled close?) and has raced in alomost every form of racing there is, including soap box. I dont consider my style of riding old school.
In stand up which takes MORE precision than soap box, i am braking 60mph on a regular basis. If we ran our bearings dry there would be a lot more seizures due to the increase of heat which is really bad when you are running your bearings dry.
and when i say more precision, we use our own bodies against the wind, you can have 2 identical people with identical boards and different tucks and the person who is more aerodynamic will go faster, even if the slower tucked person has dry bearings.
Dry bearings will only give a few hundredths of a sec faster, if that and is not worth the risk in standup. where making your back a little flatter will save a few secs.
By the way your opinions are apprecited.

no rob, pencils have graphite in it. Lead is not used anymore cuz of lead poisoning so thats why they use graphite.

I think its best for sliding parts(like no bearings)because I think the particles act as balls(huh),i'm pretty much a triflon beleiver though,that and marvel mystery oil.

Graphite is actualy good material. Used it many times for my pinewood derby car in boyscouts (i won the majority of the time) and it really helps although i didnt have bearings on it but danny does make a good point. I am going to try it on spare bearings. and danny do i have to flush my bearings dry?

Graphite comes in various degrees of size(granule wise). Go for something in the middle. This way, the graphite will wear in, and will stick to the parts when it does. Then I would slowly put a little in the groove of the bearing, where it could seep through the case into the inner parts. Then turn the bearing to let it slip in. Then hold the bearing by the inner ring, and roll it on a desk or table to get it moving around in the bearing. It is when you start riding on the bearing that the graphite breaks up and really lubricates the bearing. Does this make sense? Sometimes I have problems with words.
As far as Teflon coating, I have not seen it really too much on skate bearings, but other types of bearings. But I do know it is one of the best lubricants in the world. Did you know that the worlds largest telescope rotates not on a bearing, but 1/16" thick disk of Teflon.

Hey Danny,
Thanks for the interesting post.
When you use the graphite, how do you apply it and how much do you use? Do you use the standard powdered graphite that can be purchased for door locks?
On teflon... while I have never had any experience with actual teflon coating of parts, I have used oils that have teflon in them and had good luck. I am partial to Rem-oil myself.
Any info would be appericiated... HR

Guess? Dry bearings

On 6/15/2000 DannyT

Ok, I know you are all sick of this topic, but I have to say a few things.
Graphite: Very good lubricant. The concern was made that it will bunch up and dmage the bearing. The fact is, it will slowly get a more fine texture with use, and will not bunch up, but rather coat the bearing surfaces, without flooding the bearing. This is a VERY important concept. When a bearing is considered lubed, it is usually flooded with lubricant, and it is the flooding that slows it down. You see, there is a lot of open space in a bearing. When you fill that open space with thick lubricant, you are forcing all the little balls to push that lubricant around the bearing. That is slow. If the bearing's balls are coated with lubricant, then the lubricant is only resisting friction between surfaces. This is fast. When you fun bearings dry, it is faster than a flooded bearing, but slower than a coated lube bearing. Not to mention more dangerous. Fluid lubricants are slow because they don't stay in the bearing unless it is flooded with it.
There are alternatives. Teflon coating is a VERY good procedure, but hard to do. I am not sure on the cost.
The next best(that I am knowledgable of) is graphite, because of the way it will coat the bearing and become more fine with use.

I too use safety measures, I'm not stupid. I wear a helmet and gloves when I'm riding. but I was just offering advice to anyone willing to take it on how I ride my bearings. I feel that whoever said that my last step of putting lighter fluid in the wheels may have a low-viscocity lubricant in it as I hadn't considered it in the past. I feel this is a good way to ride my bearings and don't care if you don't do that, I was just offering my advice for how I ride them. If you don't like it, don't do it then, no one os forcing you to run them that way, it was just a suggestion. Ride however you want to.

Not that you all care, but the fastest I have been clocked is 35mph and I will still lube my bearings bcause that is the way they are designed to be used. MHO...

glad, and just want u to know i do take saftey into consideration, i recently practiced with a few speedboarders, and all i'm gonna say is that i'm glad someone there had a cell phone.b Seeing someone in shock, with a crapload of blood is not fun at all, it makes u think. having to drive someone's car to the hospital 'cause they're not there is no fun either.

Doobie,
If you read my post a little closer you will note that what I said is that "the speeds you all are talking about are on the low end of stand up skating"
And yes, 45 mph is the fastest I have been clocked at in the past 20 years. And in fact, 45 mph is the "low end" of stand up downhill skating. That is why I am not competing. I would not consider myself worthy competition until I am able to run 50 on any given day. I am not there yet.
If you get to the point (and who knows you might be there already) of attempting those speeds standing up and you ride with others who can acheive those speeds too, and you watch a guy crash. Then you may see the importance of not pushing the safety envelope in order to make up 0.001 or 0.003 seconds on your runs.
At this point I really must try to make you understand that I am tired of this conversation. You will do what you want, as I too will do what I want. I wish you and your buds no ill will, but I do not wish to discuss bearings with you any more... have fun... hugh r

oh yeah, you guys mentioned that soap box wheels are farther away from the ground and get less dirty, well the bearing is directly on the outside of the wheel, and on a skateboard they are usually recessed inside. so how does it get any dirtier than a bearing that is on the outside of a wheel? And Hugh, you said that the speeds in a soap box car are just a fraction of on luges and speed boards? Did you hear me say 45MPH? you ourself were saying that that was faster than you in the Events forum.

and if i were u, i would be much more worried about hitting a car then what procedure u use to lube u'r bearings. This is foolishness, we are involved in an extremely dangerious sport where 100's of things can go wrong, and u'r worried about u'r bearing lube? ha. hope i meet u in the Gravity games in 2 years and beat u'r @$$.

hugh r, seemes that u don't understand very well, i'm using the derby as an example of the procedeures used, and that dry bearings is common, not some freak idea. u misread my last entry i guess, i was talking about speedboarding and streetluge on the subject of frying bearings, u would have to get u'r bearings EXTREMLEY hot, as i said, in order for them to sieze up. bearings are bearings, u don't seem to understand that, and i bet u $100 that u will never experience a dry bearing siezing up during a run.

I have never tried graphite in bearings. I do use it in other non-critcal lube applications (hinges, keyed locks, model rocket launch rods) with marginal success.
My concern with graphite in bearings would be that I don't believe that it would provide enough coverage. With oils, especially thin oils, they will flow to cover all surfaces. I have never experienced the graphite dust (or are they granuals?) to have this property. I would also be concerned with the posibility of it bunching up and becoming a seize partical itself.
I will be curious to hear other opinions on this issue too... HR
