Is there any remedy for the tenon hole to open up?

The tenon hole is widened, and there are two ways to remedy it. One is to make a tenon according to the existing tenon hole; The second is to make a filler according to the size of the existing mortise and tenon hole, and the mortise and tenon hole will be filled with woodworking glue, and the tenon hole will be opened in the position or the original position after the glue is dried.

If it's a normal thing, it's safest to open a larger one, and if it has to be that big, you can open a little bigger and insert it into a circle.

Thread: A thread is a graphic composed of wire types, and there are many types of it. The most intuitive is the spiral protrusion with a specific cross-section made on the surface of a cylinder or conical matrix.

Threads are divided into cylindrical threads and tapered threads according to their parent shape; According to its position in the matrix, it is divided into external thread and internal thread, and according to its cross-sectional shape (tooth type), it is divided into triangular thread, rectangular thread, trapezoidal thread, zigzag thread and other special shape threads, triangular threads are mainly used for connection, and rectangular, trapezoidal and zigzag threads are mainly used for transmission; According to the direction of the spiral, it is divided into left-handed thread and right-handed thread, and the right-handed thread is generally used; According to the number of spiral wires, it is divided into single wire thread, double wire thread and multi-wire thread; The connection is mostly single-wire, and the transmission is double-wire or multi-wire; According to the size of the tooth, it can be divided into coarse thread and fine thread, etc., and can be divided into fastening thread, pipe thread, transmission thread, special thread, etc. according to different occasions and functions.

What a thing?

If it's a load-bearing place, or a place that requires precision, I think forget it, if it's a normal thing, it's the safest way to open a larger one, and if it has to be that big, you can open it a little bigger and inlay it into a circle.

Saw the supplement ......

Blind holes in the gearbox body? Screwed into the fastening screws? If there are only free bits, open one larger one.

The key is to look at most of the good, if the rules are shaky, then there is no need to remedy!

If the threaded hole is not a through hole, if it is not a through hole, the thread accuracy is not high, and the stop gauge is not too shaky, just find a taper to knock on the empty mouth!

The difference is not too much, you can plating it, copper or chrome.

It depends on what kind of material it is, how much tension is required, if it is a general tension, it is good to expand the number one braces, and a braces are only three or two yuan.

The mortise is large and the tenon is small, so make a wedge and add it to the mortise, preferably with glue, so that it is firm.

If you have time, let's go long distance. In fact, running long distances will cause little damage to the car, as long as the car moves, there will be damage, and the car will accelerate the aging of various parts of the car if it is not driven for a long time. It's only a minute to get to work, and it's really too short, and you may not even be able to get the water temperature.

In this way, the biggest victim for a long time is your battery. It consumes a lot of power to start the engine first, and then you have less charging time due to the short driving time, so your battery life will be greatly reduced in the long run. When it comes to running at high speeds, just don't go too fast.

In addition to charging the battery enough, running at high speed can also help the engine remove carbon deposits, so there are many benefits to running at high speed. Of course, you still have to pay attention to safety when running at high speeds, you must check your tires before and after every run, and fasten your seat belts in the front and rear rows when driving!

A little impact, because long-term running in the city, the speed is very slow, and your driving distance is short, the engine can not reach the best working condition, resulting in high fuel consumption, more than a long time the engine carbon deposit will be more, but the damage to the car is very small, it is nothing more than to clean up the carbon deposit regularly.

The mileage of running is small, it is recommended to change the oil frequently, you can change it to change the oil every 2-3 months, do not need to change the oil too well, the yellow shell mineral oil can be, more than 100 yuan a barrel.

Or the second scheme can also be changed to full synthesis, every 10,000 kilometers or 1 year, the price is around 400 yuan.

The choice is yours, and I suggest you go for the first option, which is both economical and always with a new oil.

Your car is the most fuel-intensive, the cold start and start of the car is the most fuel-intensive, and it is also the most worn, the water temperature has not yet come up, and the car has not reached the best condition, and it has reached its destination, so you have to run long distances often, and you have time to run on the high-speed high-speed, otherwise it is easy to accumulate carbon.

This is the need to run a long distance, take your wife and children, and go on a trip!!

This doesn't matter, but when you are in the run-in period, pay attention to the speed and rotation, and after the run-in period, you go down the high-speed.

In fact, you don't have to worry about the vehicle of what short-distance wear and tear is large, as long as your car is then opened, but the short-distance fuel consumption is relatively high in comparison, you can choose to drive out on the weekend to travel, whatever, you have only driven a total of 2000 kilometers now, it should not have passed the run-in period, the run-in period needs a good run-in, it is best to drive high-speed and then run in the city, the run-in is good, and the level of fuel consumption will still have an impact on the future, the specific reason should be no matter what the car, At the time of delivery, there are still uneven places in the cylinder body of the engine, so it needs to be run-in.

For the situation you said, I will give you a way is that the maintenance must be done regularly, and secondly, because your current vehicle is still in the run-in period, it is best to let the car run at high speed, which means that the speed of the car is as stable as possible, and the meaning of running high speed is here.

It's okay to bubble at high speed, pull up the rps.

Sell it, take the bus, save money, trouble and effort.

The glass can not be cut after tempering, and can only be cut before tempering. You can only change this situation.

Scheme 1, repair welding. Welding rods with cast iron. The second option is to continue to make it larger, and then inlay a matching sleeve and reprocess it.

Two commonly used tricks for mechanical repair. Hehe.

How big the hole can be smoothed after tapping the screw during processing.

It depends on what kind of parts are used differently or require a finish, so don't let the repair weld. If the hole is big, it will be scrapped directly! But you're a cast of iron, and it's hard to recast it. . .

It doesn't have much effect on the future. This is very common in college, the school will not embarrass you, and you will still graduate normally when you graduate. Go to the inkblot ink teacher or counselor, university teacher is easier to talk to.

If you ask the teacher, you must know how to be flexible. Like one of our classmates, I went to discuss with the teacher, as long as the teacher asked him to not fail the high math at the end of the semester, he would sing 20 songs to the teacher, and the teacher really agreed. So it's also a technology.

But in fact, it really doesn't matter if you fail the course, and you will pass it in the end.

If the results are not out yet, you can communicate with the teacher, the general teacher will be accommodating, if the results come out, it has been hung up, then you have to make up the exam, and the teacher asks for the content of the make-up exam when the make-up exam is very good, and it is generally passable.

Failing the subject is failing the course, and the make-up exam is not enough. If you are going to graduate school, you will not be looking at your usual grades. If you are looking for a job, most companies pay more attention to your recent developments, so it is best to write your resume in reverse order from senior to freshman.

If the school score checking system has already shown it, unless you know someone, you can't help it. If it's just that the teacher shows that the subject has not been entered, and the system has not yet entered, just ask the teacher for a favor and have a better attitude.

Ask the teacher, if it has been recorded by the teaching affairs system, there is no way, it is very serious, there are no honors such as records, scholarships, etc., and there will be many potential opportunities for less.

There is no exam in the third year.,It's okay.,I'll let you graduate.,Don't worry.。。。 Hope!!! Thank you.

It's already hanging. Retake and retake. I can't get a scholarship in my freshman year.

You'll be able to understand every word it says.
