will it be convenient to have it with horizontal big cup like thing(like a wind wane ) to help in to rotate the gear box to make the piston to move up &down to pull water tru a piston.(hand bore well pump) in this terms i need a perfect design with locally available material

Get an old bicycle wheel and attach vanes to the spokes to make your water wheel and it's pivot.

Funny i have one of them too. I suggest to go to google search and put in 'outboard motors' I am sure you will come across a really good site. \nGood luck and e-mail me if you want to. lol

In hydraulics (actually I think they're pneumatic), you can always develop leaks from excessive force. They are pretty sufficient at completely dampening the engine movement and vibration. There's not much to them except a sealed bladder and a spring. They're also very difficult to install. With rubber mounts, the rubber can dry-rot in about 10 years or less. Unless you pay a pretty price for the hydraulics/pneumatics, I'd stick with rubbers. Cheap parts always have problems.

No, don't drill it.\n\nthe valve type is PRESTA, dude\nthere are two types of valves out there, shrader and presta.\n\nyou can twist the top part like a screw, that is the part (like the cap) for a normal valve, that holds the air in securely. you twist that looser, then put the presta pump on the valve, flip the switch  on the head part, then pump. when it is done pumping, flip back the switch and take the pump off. (DONE)\n\npresta is found on bikes that are more expensive (not wal-mart junk)\n\nSimply go to a bike shop, ask for a tire in your size but in presta.\npronounced    "Press-tuh" (but quickly)\n\nIt is a better type of valve, you can get an adaptor cheap at your LBS (Local Bike Shop) (or REI) for a couple bucks, or you can buy a nice, sturdy pump (presta) with a gauge for 30-40 bucks. Don't try to fill it up at the gas station, that would be stupid. (please)\n\nI don't suggest drilling the other hole (if you must) by yourself.\n\ncheck out this site, and scroll down to "Presta"\nhttp://www.sheldonbrown.com/gloss_p.html\n\nMy idea: Buy a pump (presta) for 30-40 bucks, and get a couple adaptors just in case\n\nIt might have clipless pedals, if you have not seen these pedals before\n\np.s. google "presta" and "presta adaptor"\n\n\nP.P.S.  NICE BIKE!\nNew, it's 1600 w/o tax but with police add-ons, it's alot more.

Yes, centralized lubrication systems are quite common on mechanical punch presses as well as other large mechanical machinery.  Check the sources for manufacturers of such systems.  I'm almost certain that there's something made for your particular application.

Poppet valve would be your likely answer.\n\nCheck valve is also acceptable.

Pick a screwdriver with a straight blade (and a ratchet if you want to get complicated).  Without the ratchet as a clue it could be for almost anything, chipping bits out of softer material, scraping stuff off harder material, levering things apart, wedging things open. \nWith the ratchet it's obvious that it was designed for turning something in one direction or the other, probably the hard thin end was inserted in some sort of thin cavity and depending on the position of the lock on the ratchet you can turn the thick end backwards and forwards while the blade part rotates in only one direction. \n\nWhy on earth would anybody want such a tool? \nProbably some sort of ritual purposes.

Dude, check this out.\n\nhttp://www.youtube.com/watch?v=ZH8okt44Zgg\n\nLooks like somebody already beat you to that.\n\nThe only problem is that lawnmower motors point the shaft vertically, so there would need to be some type of drive system.

Oh yeah. Shape is everything. A sphere is the perfect shape for holding pressure. But the reason we dont see many spheres holding pressure is that they are also inconvenient in shape, so we have the next best thing - cylinders. LGP tanks, oxy tanks, scuba cylinders etc. Round sides even out the pressure, thats why you dont see square tanks. Also remember that when they test a tank for how well they hold pressure they fill it with water and pressurise the water, if you did this with just air, it will explode when the pressure gets too high. Thats called a hydraulic pressure test and it is marked on all pressure vessels. There is a test pressure and safe working pressure stamped in to all tanks.

The guys who did the Boston "Big Dig" used "box jacking" whereby a box was rammed into the side of the earth, then dug out, then rammed forward with hydraulic jacks.  The tunnel needed to be shored up as they went with sprayed concrete.  But hey, if you are just trying to get a pipe through there find a company that does lateral boring.  That's right.  They have a machine that bores down then sideways.  I have seen them install utilities this way.  The pipe should be big enough in diameter to carry the water line and electrical conduit for the pump, which should be located at the source (it will likely be impossible to locate the pump away from the source, because it will need to be primed.)

The water powered elevator. Problem is......You need a water wheel. Well....if you have a water wheel well you are probably not in a place that needs an elevator. I really need to seriously rethink this.

Depends on your application.\n\nPump water from a shallow (less than 20ft)or deep (greater than 20ft) well?\nHow much volume(gpm) and pressure(psi) are you looking for?\nBased on standard house current at 110VAC or off of a car battery(12V) and how long do you plan to have this pump running (few minutes at a time or hr's or day's on end)?\n\nYour question can be simple or a major under taking. \n\nA simple pump, using an old washmachine pump and motor you can come up with a basic pump. This will work on a shallow application, meaning the pump can't draw water from a resavoir being very deep, maybe a few feet. \nA sump pump is also a very shallow well type, works from a jet principle, but can't deliver a lot of pressure 10-15psi for a short period of time.\n\nWater wells which are deep, > 30ft, usually have the pump submerged into the water which then pushes the water out vs drawing the water up.\nSome of the older pumps were of a piston design, inefficient compared todays jet pump standards.\n\nOtherwise an electric moter and a mechanical pump.

You may need to change the foundation for the new motor to correct its height so that the pump and motor shaft centerlines are correct.  You will need a flexible coupling that accomodates different sized pump and motor shafts.  The speed and power rating of the new motor should be consistent with the needs of the pump.

Damn, I did the same thing to mine last weekend! Lucky for me, I just pushed it back into the water after running up on an unseen sand bar - and it started right back up, no problems.  I dunno about yours though -- I guess it would really depend on how much debris you sucked up in the intake. I think all I had was a little bit of sand, no rocks. Gotta be careful not to damage the turbines. If it's bad, I'd probably call Yamaha and get them to tell me what they thought. Good luck.

I believe it developed on time as a practical ecomonic choice or industry standard.\n\nYou would want to use a very low pressure if possible but still it needs to be high enough to actuate instuments and control devices.

We make small display rotators if you check out our web site you can get an idea how we build them. You probably just need a slower gear motor. You can change the pulleys for different speeds but then you need to change the belt size. It is always easier to get a motor close to the final speed you want.\n I don't know what the cabinet looks like or what kind of space you have for the motor but it may help to see how we build them. www.semcomotion.com
