- Q: okay...lemme explain...i have an experiment in my criminalistics class on improvised weaponry and I figured, hey, stupid...(that's me) this sounds like a great(dangerous and stupid,with potential for serious bodily harm) idea. Gee, wonder what would happen if I do it?(most likely,PAIN.)how much damag would this cause to a human body? car? building, such as a wood shed(mine)....can this be done? will it destroy my(roommates, cause I sure as hell wont do it to mine!) gun? anyone know how quickly the ball bearings would come out? damage they'd inflict/ etc?any help would be enormously appreciated!
- If you used a bearing the same size as the average paintball, it may not go very far. A burst of air is what propels a paintball a paintball is definitely lighter than a ball bearing. There may not be enough air pressure to propel the metal bearing. If you use a bulk of smaller bearings, like a buckshot effect, those would barely come out at all. There'd be too much air blown around the smaller bearings, resulting in little air to actually propel the bearings. The reason it wouldn't come out as fast or far as a bb or airsoft gun is because a paintball gun isn't DESIGNED to shoot bb's. In any case, it isn't a safe experiment. If you were to try it, better make sure you take every possible safety precaution. And use your own gun, either buying a used junker or something cheap. As for the damage to the gun, there'll be some scratching/denting of the breech, bolt inside the barrel. Won't exactly break the gun completely but it won't shoot paint the same afterwards.
- Q: Is it important to replace the rear wheel bearings both at the same time (both left and right)? Or is that only done because of convenience (to save the trouble of replacing the other one in the near future)?
- What occurs in case you spin the wheel by way of hand? Does the project in easy terms happen while under load. If the clunking is time-honored, yet quickens as you advance highway velocity then it truly is in all risk bearings or chain. Bearings: with the wheel in place, you on the ingredient of the motorbike, draw close the precise and the backside of the wheel. are you able to sense flow once you push the precise far flung from you, and pull the backside in the direction of you? Rotate the wheel ninety degree and attempt lower back. in case you are able to twist the wheel this way then you definately've duff bearings. The chain: it truly is available for pins interior the chain to break, yet with out the chain breaking. i've got additionally had a ingredient plate ruin. the two issues might reason a rhythmic clunking. you're able to desire to furnish the chain a radical sparkling, oil, and inspection. seek for cracked ingredient-plates, stiff chain hyperlinks, something somewhat unusual. it truly is a actual soreness while a chain breaks.
- Q: how do theymake steel ball bearings so perfectly round and of the same size?
- A okorder
- Q: This is a mid-1970's Schwinn. Obviously, if there is grit or dirt or rust I will clean them. My instinct is to use 3 in 1 oil if I must, then repack everything in good old reliable bicycle grease. But if there is just old grease without anything gritty, do I even need to clean the bearings etc., and if so, what cleaning agent do I use?
- any other like item such as Park polylube 1000 is fine too. Dont use 3 in 1 oil it is too viscous and will break down as a lube in bearings .
- Q: Right now I'm riding on Element Skate Bearings and I tear them up real easily. I mostly ride street, so of course smaller wheels. What do you guys recommend?
- Bones Labryinth, Or Ceramics. Highly expensive.
- Q: and what are they used for?
- the bearings are inside the wheel. depending on the abec rating depends on the speed. two bearings for every wheel and your set.
- Q: How do i use the law of cosine to find bearings.For example:On a hiker's map, point A is 2.7 in. due west of point B and point C is 3.4 in. from B and 4.1 in. from A, respectively. Find the bearing of A from C and the bearing of B from C
- law okorder / the solution I gave is correct assuming C is north of A-B because bearings are taken CCW from N. the solution you are reporting is correct if C is south of A-B — a bit of information not provided. ??
- Q: I have this set of bearings i got recently with my skateboard deck i purchased on ebay, the board and bearings are brand new from 1988, the bearings was in there original package. When i took the bearings out they dont spin very much at all. They only read 608 zz on both sides and they come with silver spacers. Are these good bearings and if so, how could i beable to get these to work more better.
- More okorder and order some good bearings is my suggestion. If you want some high class bearings get Bones Swiss or Black Panthers, but any bearings on this site should be pretty good bearings. Price range from about $10-45.
- Q: Difference between rubbing bearings and roller element bearings?
- With roller bearings there are small rollers between the moving and non-moving part so that there would theoretically be no friction. Ball bearings work in a similar way.
