What happens if you leave your oil dipstick out and then drive the car?
It's possible that you'll burp some oil out of the dipstick tube provided the tube is short and in a location where oil is moving around at speed, and yes it's possible that you'll get some contaminants in the oil provided this condition is sustained for long enough as it's essentially a path directly into your oil supply from the outside environment which is usually dirty.I think more interestingly this could cause a vacuum leak as many cars operate with the crankcase (inside of engine where the internal components operate) under a vacuum to scavenge pollutants and re-burn them. Depending on the nature of your engine's emissions system, a hole from the outside air into the crankcase could affect the air metering system and thus cause the engine to run suboptimally. There are too many variables to draw any specific conclusion but to make it short; it probably won't be catastrophic but can't be good.
How can I make a stick for a bow and arrow strong and not break, but also make it bendable?
I have built exactly one primitive bow, so take this for what it's worth. I did however build it the right way and the result is pretty solid.You need a long straight piece of suitable wood. By wood, I mean a piece of tree and not something from the lumber yard. Find and fell a tree 6 inches or so in diameter. You need 6 feet or so length that is straight and has no branches or limbs. Ash or yew are traditional choices but most hardwoods will work. The goal is to get this length of wood with as straight a grain as possible. But you won't know if you chose right until you start splitting.Now get a hatchet, a hammer, and a bunch of wedges. It's time to split the wood into the proper size blank. Cutting the wood with a saw will result in broken grain. You want your bow to be made of continuous unbroken woodgrain from top to tip. A tool called a froe, is useful but splitting the log can be done with just wedges.Split the log into 3 two inch planks. Two of them will benarrower than the middle one. Separate the middle third of the two narrow planks and keep it. Split out the middle third of the wide plank and throw it away. Save the two outer thirds from the wide plank. Strip the bark and softwood from each blank.Season these blanks in your home's attic for two years.Use a spokeshave to draw down the thickness of the bow's arms leaving a handle in the middle.Saturate the bow with tung oil and let dry. Repeat a dozen times or more.String it.You now have a bow much like that used by the famous English archers of old. There are many ways to improve upon it. Laminating different woods. Laminating with deer sinew. But at it's heart, you now have a bow that will probably not break.Now, if what you really want is a bow that works and is easy and cheap to make… go to your nearest thrift shop and buy an old pair of cross country skis. They make a great choice for bow material.I have also seen some surprisingly effective PVC pipe bows but they look so aweful.Good luck.
How can I get the dipstick out of my oil pan?
My car's dipstick broke off at the handle when we were checking the oil and fell down into the oil pan. The car is a 2004 Nissan Sentra, and I don't know how to get it out. We have the handle piece, but the actual metal part is what fell down, and I think it requires removing the oil pan to get the piece out. My question is really, can I leave it in there without damage, or will I have to pay to get it removed, or even, can I do it myself?
How do you remove a stuck gas cylinder cap?
Safety first! Make sure the tank is well secured so that it won't turn or fall over.Do not use oil based penetrating oils on oxygen cylinders. Methyl salicylate (oil of wintergreen) is a little known, but highly effective rust cutting penetrant. WD-40 and Liquid Wrench are good too.Tap around the cap, where the threads are, with a non-sparking hammer, to loosen debris in the threads. Make sure the cap isn't cross threaded. Give the penetrant time to work.Use wrenches only on the upper part of the cap. Pipe wrenches, even chain and strap wrenches, will distort the thin metal of the cap, further binding the threads.Attempt to break the cap loose, using moderate force with leverage and a hammer, in both directions. If you get motion, move it back a little in the other direction. Work it back and forth, gaining ground in the off direction a little at a time. Add lubricant to help flush the threads and continue tapping periodically. If the cap binds while turning it in the off direction, do not try to force it. Just cycle it back and forth to loosen it up. Forcing it will only embed the garbage in the threads more deeply and possibly cause galling (friction welding) in the threads. Patience and finesse is always better than force!
What happens when coolant leaks into engine oil?
Lots of nasty things happen to your engine when coolant leaks into your engine oil. Oil loses its lubricating properties and you start getting metal on metal damage. The oil turns milky white, which tells you there is coolant in the oil. If you stop driving your engine, the coolant will start to rust everything it can reach inside the engine. It will corrode anything that isn’t iron. In short, if you have coolant in your engine oil, it is a must fix now problem, if you have any interest in saving your engine.How does coolant get there? A blown head gasket is the most common way. That is the one place in the motor where coolant is on one side of a gasket and oil is on the other. When compression blows a hole through part of the gasket, coolant can move from its channel to the oil channel and you have coolant in your oil and oil in your coolant. Neither is a good thing.The other way is to actually crack your block. This too can open a passage between your coolant passages and your oil passages. The passages are close to each other to aid in efficient heat transfer, this helps keep your engine cool.Both of these can be caused by overheating your engine. The head gasket can blow out because of poor installation also.
How to destroy a wooden bench with metal legs hammered to the ground?
You don't have to destroy it, just make it so no one wants to sit there anymore. Drop about 12 eggs evenly onto the bench, and follow up with toilet paper. When the two mix and dry it turns into a glue as well as a paint thinner. Its also going to smell pretty ripe and if no one cleans it up before it dries completely, the stuff will be very hard to scrub off. After they repaint it, go down there with a sharpe and draw a huge cock and balls all over it. Enjoy.
Can I use my mobile charger to charge my vape pen?
Yes you can. Many of the posts are misleading. A charger will not “send” the current to the battery. I'm a trained electronics tech. Here is how it works. In its simplest form when you plug a device into a charger the voltage of the charger is passed on to the device but the device will only draw as much current as it's designed offer it at. With this in mind you need to make sure that your charger can provide at least the amount of current that the device is designed to draw otherwise you can burn out your charger. You also need to make sure that the voltage of the charger is the same as the voltage of the device being charged otherwise you can cause damage to the battery. If you do these things you're fine.For example the charger adapter that came with my vaping pen has the pin connection on one end and a USB on the other. on the back of it it tells you what voltage and current it's designed for. In my case the input voltage is 5 volts DC. The output voltage is 5 volts at 120 milliamps. So any charger with an output of 5 volts that can handle at least 120 milliamps can be used to charge my battery. Now for those who don't know 120 milliamps is .12 amps. So even a USB charger with an output of 5 amps at 5 volts would be adequate to charge my battery. Again the battery will only draw as much current as it needs.
Can you put too much motor oil in a car?
Allow me to answer your question with a true story. An older gentlemen brings his car in to the shop for repair. He complains of the engine sputtering, car shaking, bad acceleration, and horrible gas mileage. He also asks that, while we have the car, to top off the oil. He states that “it’s a little low” Sure enough, he was right about the engine problems. The car sounded like it had a horrible miss and possibly slipped a tooth on the timing chain. Possibly some rocker arms have been broken. It was bad. So, after taking off the oil fill cap to have a look into the valve covers (this was in the 80’s when one could actually see inside the valve cover) the oil was low. I mean, assuming it should be filled up to the top of the oil fill cap in the valve cover! This fine modern gentlemen didn’t realize that you fill your engine with oil to the “full” line on the dipstick but instead thought the engine should literally be full of oil. After draining 26 quarts of oil out of the car, it turned out that the engine had survived. It wasn’t the same after that, and I’d assume he really had reduced the overall engine life, but it smoothed out somewhat and didn’t shake nearly like it did when it pulled in. So yes, you CAN overfill your engine oil. You SHOULDN’T, but you CAN. Now of course this is a story of the extreme, but even an extra quart can cause your engine to have to work harder. You’re almost certain to, if nothing else, reduce your engine’s overall life by adding too much oil.
