Suspension Binding? Answered

I know this photo is different looking, but ignore that and look at the shaft.  It, like all other driven independent suspensions has no spline or sliding shaft to allow for movement in and out.  HOW DOES THIS NOT CRUSH THE SHAFT OR JOINTS.

Adding suspension to a go kart?

It it a good idea to add suspension to a go kart? It is a small go kart and already has a frame from metal tubing and small wheels. My friend and i thought it would be cool to be able to drive it off road. We are meeting up tomorrow to discuss in detail how we would design it. The basic idea is this: use a pair of universal joints attached to a rod which transfers the power from the axle to the wheels. There would also be a spring attached to a hinge where the universal joint attaches to the wheel, and the other side of the spring attaches to the frame. There would also be some sort of frame that this stuff was attached to to keep it in place. The frame would be made preferably without welding, as we have no access to welding equipment. I don't know if this is possible to do without welding, but if it was REALLY necessary, i guess we could get a welder or find someone to do it for us. We will add images of our prototype drawings tomorrow once we get them done, those should help you envision what we are trying to accomplish. Thanks for the help!

How do I replace worn out front struts on a 98 Honda Accord; and how much would it cost me? Answered

How do I replace worn out front MacPherson struts on a 98 Honda Accord; and how much would it cost me?Note; it seems I can use pre-assembled Monroe "Quick Struts"; would I still need the spring clamps if I us a quick-strut? I've heard this could be potentially dangerous; how would I minimize danger? Other things; would I need to bleed the brakes after? ( I assume yes) What's the basic idea behind that? I would need an alignment I'm going to assume, from what I hear, I can't do that at home - but can I get it "semi-right" to drive it to the shop? I have most of the tools available aside from a torque wrench. If I get a Monroe quick-strut, what other things would I replace? Any bushings/bearings/stuff that would be good to change at the same time? Personal experience, Changing oil/fixing radiator leaks/doing basic maintenance on cars (brake pads/rotors, spark plugs/ distributor cap etc) The easy stuff basically. Honda quoted me at 800, and independent quoted me at 600. I can buy those quick-struts for 180 a pop.

Independent suspensions? Answered

I have been trying to figure out how to put an independent suspension on a Huge scale RC.  What I have noticed on large cars is that unlike small RC cars the rod going from the dif to the wheels is solid and can't extend/shrink.  Why doesn't this bind up? I have also noticed that for some reason they don't line the suspension up to move exactly up and down. The wheel's pitch is actually set up to change as the suspension depresses.

Advice sought on hacking my Xootr kick scooter.

I love my Xootr Scooter. I'd probably love it even more if it didn't keep trying to kill me. I live in NYC and ride the scooter on both streets and sidewalks. The problem is that whenever the front wheel hits a sudden discontinuity greater than about half an inch, it flips, attempting to take me with it on a 360º journey that would no doubt end with my brains splattered on the pavement.  So far my reflexes have remained fast enough to leap off at the last microsecond; but I'm not getting any younger; which also means I would feel like a fool wearing a helmet to ride the same type of vehicle children so blithely scoot up and down the block on. Anyway: I've looked for inflatable tires that fit the scooter. They don't seem to exist. I've considered trying to add a suspension, but I don't weld and it's probably beyond my abilities anyway. My most recent idea is to use a drill to honeycomb the front tire with holes and then fill the holes with a 'bouncier' substance. (Sugru, perhaps?) Any suggestions, advice, or comments would be greatly appreciated.

I don't think I can drill holes into my walls in my apartment to attach them to, so I thought a free-standing frame would be a good solution, but I can't find plans or prototypes anywhere! Ideas? I would be open to other ideas that didn't involve a frame, as long as they didn't require me to drill holes into walls or rely on possibly unstable studs in an old building.  I'd like something that wasn't in a door frame, but if its easy to use and put up and take down, I'm in.

Desk Support

Hey boys and girls. Over the past couple of weeks (due to work, mostly) I've been building this computer desk, the original here, and a slightly modified one. I've built it using 3/4" MDF and have it painted a gloss black, similar to the modified version. I'm currently stuck on what to do for support. In the original, he uses file cabinets and some scrap material for supports. In the slightly modified version, he uses desk legs from Ikea.I'd like to do something simple, but I'm kinda lost. I've had two ideas floating around my head for a while but I was wondering if their were any other suggestions y'all might be able to throw at me. First, I was thinking about making legs out of chain-link-fence style posts.Then I had the idea to suspend it. Attaching a cable to the front "bulge" on each side (see pic.), and attach the other end of cable to the wall. Using a piece of 2x4, or the like, screwed to the studs in the wall to support the back edge's. (I hope that makes sense). I'm thinking suspending it might work, but would require a bit more work.The idea of a floating desk sounds really cool, but I can't think of another way to achieve the effect.Any thoughts on getting this thing off the floor, minus the saw-horses, will be greatly appreciated.

Can i increase my carrying capacity if i install heavy duty coils?

I have a 2002 Toyota Sequoia and it has coil springs all the way around. I was wondering if i merely installed some variable rate coil springs (so it still isn't like driving a rock) that have a heavier weight rating if i could load my SUV heavier. On vacation I carry 4 people, their luggage, and a small 14 foot pop-up camper. I'm using a weight equalizer hitch, and as it stands, i am maxed on the back axle and could carry 200 lbs more on the front. If i installed heavier suspension, can i expect my axle and chassis to be able to handle the extra weight? and how much more?

Seeking engineering advice on mounting heavy weight in concrete ceiling

Hi all, I am designing/building a prop ceiling-mounted surgical arm (see reference photos attached) into a 15" concrete slab ceiling for a hospital room set for a tv show. I'm also attaching two sketches of the two different arms I plan on making and I'm hoping some of you clever engineering-types may be able to identify flaws in my schematics before I go too far with the design. If you see something that could pose a danger to the actors or have and alternative suggestion I would be grateful!!! Here are my concerns: 1) what are acceptable stresses on all joints due to weight distribution and actors moving the parts around? 2) the heavy duty industrial casters that tapcon into the ceiling: would they get pried apart as weight is applied gravitationally? 3) can the concrete ceiling handle the live stresses of actors moving the arms? 4) can the horizontal PVC arms handle the weight or do they require a welded metal skeleton? --------------------------------------------------------------------------------------------------------------------- Any feedback would be greatly appreciated; I'm in my research phase of this build now so please let me know your thoughts!!!

How to add suspension to a food trolley to prevent spillage of food and tea?

I am an A level Product design student and I am designing a food trolley for a person with grip and stability issues.  One of the biggest problems with current models is that when they go over the slightest bump or carpet runners/plates e.g. and they will spill and tip whatever is on them. This is a massive problem if the user is carrying hot tea or their dinner, increasing clean up work and generally reducing the quality of life of the user. I cannot think of a relevant method for stabilising the food tray/drink holder without drastically reducing the overall function and massively increasing cost while still allowing the trolley to support the user while they take their food from the prep area/kitchen to the eating area.  A few Ideas I have had:  large pneumatic wheels (solid rubber in most other examples), Some sort of spring suspension, Pistons, A counter weight... I have tried researching stabilisers for cameras but they don't seem to be relevant. Help with research keywords would also be useful as its difficult to know what to look up. Another problem I'm addressing is the aesthetics of the product as most examples just look like hospital equipment not everyday furniture. Currently I am siding on wood as the main material for the frame, If anybody has suggestions that would be better than boring tubular steel I am still in the early stages of development and would appreciate inspiration!

How do you make a salve? Answered

Origins used to make a cream called "Leg Lifts." It's loaded with menthol, Eucalyptus and a bunch of other stuff that makes your skin tingle. I would use it after really long bike rides and it was like a cooling chemical massage. They have now stopped making it and no more is available so I was hoping to reverse engineer it. It was a smooth cream the consistency of ketchup or a heavy hair conditioner. I think I can work out the things that make your skin tingle, but I have no idea what to use for the suspension medium. I searched for foot creams and salves and what I found didn't seem like a good fit. I figure once I come up with a suspension medium, I can just add powdered menthol, eucalyptus, tea tree oils and such until I get something that does the job. What could I use for this suspension medium? It has to be pH balanced, hypoallergenic and edible.

Making a magnetically suspended puppet. Answered

Hi, I'm thinking of making a magnetically suspended puppet. The idea is to make a puppet with a neodymium magnet in its head, and suspend it under an electromagnet, using a microcontroller to control the (DC) suspension current. To regulate the current, I'll probably use a D/A converter chip controlling an op-amp current sink, though I might use low-pass filtered PWM D/A conversion. I was thinking of a way of sensing the vertical height where I put a small chunk of metal in the head as well as the magnet, modulate the suspension field slightly at a high frequency (20 kHz?), and have an extra sense coil around the suspension coil. The idea is there would be an induced current in the sense coil from the modulation. This would change as the metal chunk came nearer to the centre of the coil. The signal from the sense coil would go through a high-pass-filter (to remove any low frequency components like mains), an op-amp rectifier, and then a low-pass filter, to produce a sense voltage. I might try both para- and dia- magnetic metals (iron and aluminium) to see which works better. I'm not entirely sure whether this will work, but I'd like to try it as it seems more elegant than using a hall effect sensor. The questions I have are: - How would I go about calculating roughly what length of wire and current I'm likely to need to suspend a given weight? Just a pointer to the relevant maths should be OK - don't feel like you to have to spell it out. - Does it make any difference whether the electromagnet is long or short along its central axis? I had an idea that the field from a longer coil might extend further below the magnet than one from a shorter one, but I don't know if this is so. - Does the method I've described for sensing the height sound practical? Thanks for any help, andy (ganglion)

Air ride bicycle suspension

So i've been interested in pneumatis for quite some time and recently I came across a small air cylinder (6 inch travel), 12 volt air compressor, 12 volt valve, and misc fittings. I got really excited and without thinking twice I grabbed tools and started hacking up my old beach cruiser (it was quite a mess anyway after 3 trips to burningman). So this is the outcome... I can control the up/down with a momentary on switch out back. Now just looking at this mess its easy to see that well i obviously can't weld. Never tried... Anyway it rides really sloppy as you can imagine, much like an old Lincoln with the shocks blown out, but it is so much fun! Now i pose the question to you community members, how would you have done this different? Looking forward to your responses!
