Cut Golf introduces Cut Blue DC golf ball – featuring higher compression and 360 dimple pattern – GolfWRX

Dustin Johnson shot a round of 1-under par at Liberty National on Thursday, and under the circumstances, it was one of his best under-par rounds of the year.

The 37-year-old encountered adversity in New Jersey when he noticed a crack in the crown of his driver right before his round. With no replacement, DJ had a 3-wood retrieved from his car, which made its way into his bag on the second hole.  

Explaining his setup from then on, DJ told the media

“I’ve got a 5-wood that I use for my 3-wood. It goes the distance I want it to. But I had a strong 3-wood (14.5 degrees) in my car, so it helped a little bit … the first time I hit it was on 8. Just, I hadn’t hit it. It was brand new. So I hit it down the middle on 8, hit a good one, hit a good shot on 9. I hit it nicely, though, with it.”

Johnson gained half a stroke off the tee despite not having his trusty driver in his bag, and he believes that even if the 3-wood wasn’t retrieved from his car, he’d have been just fine: “I would have figured out a way. I figured out a way to shoot a decent score.”

As for Friday’s round, expect to see DJ with a driver as Keith Sbarbaro, TaylorMade’s Tour rep, has come to the American’s aid: “I’ve got a couple heads that I’m going to go try to hit. Keith got me a couple heads.”

The extra 3-wood wasn’t the only big change in Johnson’s bag on Thursday either, who decided to sub in his old TaylorMade Spider, having been playing a blade-style gamer in recent weeks.

“I switched back to the Spider right before the round. I’ve been using my blade for a while. I was hitting some putts on the putting green this morning, and it didn’t feel too good, so I went and grabbed my Spider.”

How to make a part of parts uncut in a section in SolidWorks?

Hello everyone! Today, in a small lesson, we will analyze how to display part of the parts uncut in a section in a SolidWorks drawing.

You need to know to display
parts in sections in assembly drawings. For example, according to GOST ESKD in the drawings
when longitudinal cuts are not cut, the following are displayed: non-hollow shafts, bolts,
screws, pins, dowels and, regardless of the type of cut, undisturbed
balls are shown.

And so I’ll show you how to do it on
an example of an assembly performed in the lessons: “Creating an assembly in Solidworks” and “Continuing the assembly of the crank-yoke
mechanism in SolidWorks “

Open this assembly.

Assembling the crank-rocker mechanism in SolidWorks.

And immediately proceed to creating a drawing from an assembly. You can learn how to do this in this lesson: “Assembly drawing of a crank-yoke mechanism in SolidWorks according to GOST”.

Select the view as the main view
front, my scale is 1: 1.

Main view of an assembly in a drawing in SolidWorks

Next, we make a cut along one of the
axes. I followed the picture below.

Section A-A of an Assembly in SolidWorks

The parts in the red box are highlighted
which should not be dissected according to GOST ESKD. This key, washer, nut and
cotter pin.

To display them not
dissected, that is, without hatching, you need to open the section properties in SolidWorks. This is done simply:

1. Selects a section in the drawing tree on the screen
   left.
2. Click on the section with the right mouse button and
   click on the line “Properties”.
3. The properties window opens, in it go to
   the Section Indicator tab.
4. Select by left-clicking on
   parts that should be uncut in the section and click OK.

Selecting Section Properties in a SolidWorks Drawing

Section properties in SolidWorks with selected parts to undo the section.

The selected parts are surrounded by a box, and
their dissection is canceled. And section A-A now looks like this.

Cut after undoing cut for key, washer, nut and cotter pin.

Now we have figured out how to display part of the parts in SolidWorks section without dissection, and we will be able to apply this when working.

I would also like to remind you that software templates

page.
That’s all.

See you in the next lessons!

The Vintorez silent sniper complex and the Val special assault rifle developed at TsNIITOCHMASH

Dec 24.2020 01:46 PM

Developed in the 1980s by the Central Scientific Research Institute of Precision Engineering (TsNIITOCHMASH, part of the Rostec State Corporation), the Vintorez silent sniper complex and the special Val submachine gun were described by American expert Caleb Larson as an example of “excellent Soviet weaponry. ” “The fact that they are being produced today testifies to their quality and indicates that they will be used by Russia in the future,” he wrote in the article “Russian special forces can kill you.Even if you have a bulletproof vest “, re-published in December this year due to the great interest of American readers on the site” National Interest “(The National Interest, https://nationalinterest.org/blog/reboot/russia’s-spetsnaz-special- forces-can-kill-you-even-if-you-have-body-armor-174333).

“They cut body armor like cheese” – the subtitle of the text fully reflects the essence of the question. Since the late 1980s, NATO has worked to improve body armor.They protected the soldiers from the standard 5.45×39 mm AK-74 cartridge, which gave the West a clear advantage on the battlefield. Therefore, the Tula designers have improved the cartridge for the Kalashnikov assault rifle by adding a steel core.

At the same time, TsNIITOCHMASH began to create special silent weapons for special units. The requirement is to pierce the NATO bulletproof vest. The silent sniper complex “Vintorez” was created, which was adopted in 1988 by the special units of the KGB of the USSR.Later “Vintorez” entered service with the army and the Ministry of Internal Affairs of the USSR.

After the sniper complex, TsNIITOCHMASH developed a special machine gun AS (ROC “Val”), which in 1989 was also adopted by the special units of the KGB of the USSR, and a little later, and other law enforcement agencies.

“Soviet gunsmiths came up with two strange looking, but deadly quiet weapons products: VSS Vintorez and AS Val,” the expert writes. “They are completely unique; best suited for night battles or for reconnaissance teams moving quietly behind NATO lines. ”

Special designed 9×39 cartridges with subsonic muzzle velocity provided Vintorez and Val with a high destructive effect. A significant reduction in the sound level of the shot, provided by the integrated silencer, increased the comfort of using the weapon. “This steel cored cartridge delivers incredible impact and can penetrate 10 mm of steel,” concludes Caleb Larson.

Repair sleeves for shafts – DICHTOMATIK

Repair shaft sleeve WSH

Description

Product Group: WSH Shaft Repair Sleeve

Material: stainless steel 1.4301 (AISI 304)

Mounting sleeve material: carbon steel 1.0330 (SAE 1008) or 6063 aluminum or JIS G3302 steel

Operating limits

Service limits such as temperature, peripheral speed and pressure are determined by the selected rotating shaft seal. Typically, WSH covers operating parameters for all standard rotating shaft seals.

Applications

WSH Repair Shaft Bushings are used to repair the surfaces of grooved or worn rotating shafts, for example. in drive technology. They offer a cost effective alternative to replacement or time consuming repair of a worn shaft as they simply slide over the worn sliding surface.

Deep grooves can cause the original shaft seal to be replaced with a rotating shaft seal with a smaller bore, as the original diameter has been significantly reduced by reworking the shaft. This grooved shaft problem in the sliding surface area can be quickly and easily resolved using WSH, without the need to dismantle and rework the shaft or use a different size rotary shaft seal.

Naturally, WSH can also be used as original equipment for machines, assemblies or installations in order to avoid complex, costly and in some cases also complex machining of the sliding surface on the shaft.

Feature and Benefits

Using WSH to repair the shaft ensures that full functionality is restored quickly and permanently.

The repair shaft sleeve is used as a counter face for the rotating shaft seal in the tribological rotation system, that is, in addition to the rotating shaft seal and the lubricant used, WSH is the third important component.

WSH shaft repair sleeves offer the user the following benefits:

– Fast and easy repair;

– Cost-effective restoration of the sliding surface on the shaft, as there is no need to dismantle and rework the shaft

– No costly machine downtime as repair times are minimized.

– Inexpensive repair method

– The sliding surface of the rotating shaft seal is restored to full functionality

– Optimally treated and wear-resistant surface guarantees a long service life

– Maintaining the original dimensions of the seal

Installation

Installation of the WSH is very simple and time-consuming as it can be done with a mounting sleeve and a removable mounting flange.However, WSH bushings must be installed very carefully so that no damage occurs during installation and good sliding and sealing characteristics are achieved in combination with a rotating shaft seal.

The next step is to clean the sliding surface of the rotating shaft seal on the shaft and check for damage, as due to the thin wall thickness of the WSH, the roughness on the shaft can be transferred to the surface of the WSH and therefore has a negative effect on the sealing effect. Any burrs should be removed and grooves, notches, gouges or significant unevenness should be smoothed out using a suitable epoxy filler. In this case, the WSH must be attached before the filler cures.

WSH shaft repair sleeves are placed over the worn sliding surface according to the following installation instructions, thus providing quick, easy and cost-effective repairs.

Installation Instruction

1.Clean the surface of the worn shaft and remove any burrs.

2. Measure the shaft diameter at 2-3 different locations near the worn area and select the WSH bushing.

3. Lightly lubricate the shaft surface before installation (facilitates installation).

4. First install the WSH R, flange side, onto the shaft.

5. Insert the mounting sleeve over the WSH. If the mounting sleeve is too short, the pipe can be used as a mounting sleeve.

6. The WSH R is pushed through the worn area by gently tapping the mounting sleeve with a hammer (or suitable press).

7. To remove the mounting flange on the WSH, cut to the specified break point with side cutting tools and pry the flange along the broken line.

8. After installation, check the surface of the shaft again for burrs.

9. Lubricate WSH R before installing the seal.

10. Install the rotary shaft seal.

Disassembly

Shafts for shaft repair WSH can be removed from the shaft in various ways, namely:

– heating – thermally expanded WSH can be easily removed from the shaft without damaging it

– by gently tapping on the width of the sleeve with a hammer – the shaft repair tube is stretched and can be easily removed

– tearing off the repair shaft sleeve using side cutters

– cut the shaft of the repair sleeve with a chisel

Shafts for repairing shafts WSH cannot be reused.

what types, sizes, how to change correctly

Angle grinder (angle grinder), in common people called “grinder”, is widely used at construction sites and in everyday life during repairs. It can be used to carry out many different technological processes.In order to choose the right tool for performing a certain type of work, you need to familiarize yourself with what kind of disks and nozzles for angle grinders are. The tool for this device is selected by size and function.

Typical Rim Sizes

When choosing a disc for a grinder, you must make sure that the outer diameter of the attachment does not exceed the maximum permissible values ​​allowed for your angle grinder. For example, if a grinder is designed to use a circle with a maximum diameter of 125 mm, then a 230 mm circle cannot be installed on it.And there are several explanations for this:

• the linear speed of the cutting edge will be exceeded, which is fraught with the destruction of the abrasive wheel and injury to the user;
• a small grinder does not have enough power to work with a large tool;
• Installation of a nozzle that exceeds the permissible dimensions requires the removal of the protective cover, and this is already a violation of safety rules.

Discs for angle grinders have standard sizes: 115, 125, 150, 180 and 230 mm.In modern grinders , the landing diameter of (the diameter of the shaft on which the tool is installed) is practically the same and equals 22.2 mm. If you have an outdated grinder “lying around”, then you will need to use adapters – rings of different diameters.

All abrasive wheels of any size have special marking , from which you can find out the following information: disc diameter and thickness, seat diameter, maximum rotation speed, and what materials it is intended for processing.

Purpose of discs and nozzles

Grinder wheels differ in purpose for:

• cut-off;
• rough
• grinding;
• sharpening tools.

Cutting discs

The most frequent task performed with the grinder is cutting various materials. The choice of tool material also depends on what material needs to be cut.

1. Cutting metal .The metal cutting disc is made from crystalline alumina corundum, as well as from a synthetic corundum called fused alumina. The main color of wheels for cutting metals is blue.
2. Cutting stone and concrete. For stone cutting, choose a disc made of a different abrasive material – silicon carbide. This abrasive easily cuts white brick (silicate) and slate. But to cut red brick, some types of concrete or ceramic tiles, this circle material will not work.Stone discs are available in green.
3. Cutting ceramic tiles, red brick, porcelain stoneware and concrete . For these purposes, a diamond disc is already used.

   This nozzle is made of metal, an abrasive mass with diamond grit is applied to the cutting edge. The picture above shows a segmented saw blade designed for dry cutting of material. All-metal discs require water cooling during operation.

4. Wood cutting. Although saw blades for wood are commercially available that are no different from circular saw blades, it is best not to use them for safety reasons. When working with such a tool, the user is often seriously injured due to jamming, bouncing, accidental slipping of the tool, etc.

Therefore, if you are still going to use a saw blade for wood, then you should adhere to safety measures. A protective cover and a handle must be installed on the grinder, the user must wear a protective mask or goggles.In addition, you must not use this tool to cut materials that are not intended for it.

The safest discs are considered to be for wood, at the end of which a chain from a chainsaw is installed. If the tool becomes jammed, the chain stays in place and the disc rotates idle, reducing the likelihood of injury to the user.

Rough

If it is necessary to remove a layer of paint or other application, as well as rust from any surface, apply brush .They are disc-shaped or in the form of a bowl with built-in metal wire.

The wire in these attachments can be twisted or loose. Its thickness can also be different. The thicker the wire, the coarser the roughing disc or bowl is used, and vice versa.

Grinding

Grinding discs and attachments are used for grinding and polishing various surfaces (metal, wood, plastic and others). Often the flap type grinding wheel is used for grinding.It consists of many “petals” made of sandpaper. The grit size of the sanding paper can be selected based on the type of processing required (finishing or roughing).,

The sandpaper can also be attached to the attachment with Velcro . Such a tool is screwed onto the spindle of the angle grinder.

For surface polishing, special discs and attachments are produced that look like felt pillows or cloth discs.

Grinding

Grinding machines (sharpeners) are usually used to sharpen tools.But if you do not have the latter, but have a grinder, then you can purchase a sharpening (grinding) wheel for it, with which you can easily sharpen almost any cutting tool.

The main difference between grinding wheels and cut-off wheels is their thickness (at least 5 mm).

How to properly change the disc on the grinder

Since the circles for the grinder are a consumable, sooner or later they have to be changed. They are attached to the spindle of the angle grinder using a clamping flange (nut) with an M14 thread.To unscrew it, a special open-end wrench with pins on one side must go with the grinder.

So, to replace the tool on the grinder, follow these steps.

1. De-energize the machine by unplugging the power plug.
2. Lock the angle grinder spindle using the button located on the front of the case. When the button is pressed, the stopper enters the hole of the disk installed in the gearbox, which fixes the spindle in a fixed position.
3. Insert the pins of the key into the holes on the hold-down flange.
4. While holding the latch with one hand, turn the wrench to the left (counterclockwise) with the other hand until the nut breaks loose. Then it can be unscrewed without a key and removed from the shaft.

   In this case, the angle grinder spindle rotates clockwise. But in which direction to unscrew the nut if your apparatus rotates the shaft counterclockwise? Remember: the clamping flange should always be unscrewed in the direction opposite to the rotation of the shaft.

5. Now you can change the tool after removing the old one.

   If you notice that dirt has accumulated inside the casing, remove the bottom flange and use a steel brush to remove dirt from all surfaces.

6. Next, the bottom flange should be installed in place. You need to put it correctly, be sure to align the grooves on the spindle and flange.
7. Place a gasket on top of the bottom flange . It is not necessary to install it, but it is advisable, since it will provide easy unscrewing of the clamping nut in the future, if you need to change the tool.
8. Install a new tool. Sometimes the owners of angle grinders ask themselves the question: which side to put the circle on? The answer is simple: the disc is placed with the marked side out.
9. Place a pad on the abrasive wheel. If gaskets were not included with your grinder, then you can purchase them in a specialized store, or cut yourself from thin tin or cardboard .

10. Screw the flange onto the shaft by hand. Tighten the nut until you can no longer turn it without a key.After that, holding the stopper, tighten this nut with a wrench, but no more than a quarter of a turn, otherwise the disc will begin to deform.

After performing the above steps, the tool change is considered complete.

Methods for unwinding if the disc is jammed

What to do if the pressure flange is stuck? This nuisance, when the nut is bitten, often occurs if, while working with thick and durable materials, the tool is jammed in the workpiece.In this case, the abrasive wheel often breaks, and the spindle continuing to rotate tightly tightens the clamping flange. There are several ways to spin the grinder if the disc is jammed.

With gas wrench

This method is considered not entirely safe , since the stopper can be broken, although in most cases it is possible to unscrew the nut. To avoid breaking the spindle lock, do not apply too much force to the gas wrench. The retainer is designed to withstand the force of a standard wrench.

Unscrew the overly tightened flange using 2 gas wrenches. To do this, break off the protruding ends of the abrasive wheel with pliers so that you can reach the bottom flange with the first gas wrench. Next, tighten both flanges with wrenches and turn them in opposite directions (taking into account which thread on the spindle is right or left).

Dismantling the gearbox

In the event that the retainer is broken, the gearbox will have to be disassembled to remove the tool from the angle grinder.Use pliers to break off the edges of the remaining abrasive wheel so that you can get to the bolts holding the gear cover. After that, unscrew the fasteners and open the gearbox. The cover will be removed together with the pinion shaft. Further, this shaft should be clamped in a vice, having previously laid aluminum gaskets between the steel jaws, and using a gas wrench to unscrew the flange (do not forget to determine the direction of unscrewing).

Heating nut

The nut can be heated with a gas torch, hot air gun or blowtorch.The heated flange can usually be unscrewed with a standard grinder wrench.

Sewing a jammed wheel

If, after applying the first 3 methods, the nut does not loosen, then the remaining abrasive disc between the flanges can be grinded off. To do this, follow these steps.

1. Use pliers to remove any remaining disc from the edges of the nut as much as possible.
2. Clamp a piece of sheet metal as thick as the disc itself in a vice, turn on the grinder and grind off the rest of the circle on the end of the sheet metal.

Instead of iron, you can clamp a piece of abrasive wheel in a vice. In this case, the grinding of the rest of the tool between the flanges will occur faster, and the nut can be unscrewed by hand.

But the use of a stationary abrasive wheel requires great care, because when grinding off the remnants of the tool, the geometry of the flange can be damaged. If this happens, you will have to trim the nut.

Use of penetrating grease

Liberally spray the flange-to-shaft connection with WD-40 fluid. It tends to penetrate into inter-threaded spaces and small cracks. After applying the liquid, wait about 5 minutes and try to unscrew the fasteners with a standard wrench.

Using a punch

Some owners of grinders, in a situation where the clamping nut is jammed, install the nozzle “ chisel” or “jackhammer ” into the hammer drill, insert it into the hole of the flange at an angle and turn on the breaker hammer mode without rotation. Accordingly, the stop button must be pressed.Just a couple of gentle clicks with a hammer drill are enough (so as not to break the shaft retainer), and the nut will begin to turn.

Cut the pressure flange with a hacksaw

This method can be called radical, since you will have to buy new fasteners, and it is used if the nut is not unscrewed by any other methods. To cut the flange, hold the stop button so that the shaft does not rotate, and using a hacksaw , cut the retaining nut.
