How to make sanding tips. Let’s make a tooling with our own hands

Sanding drum from leftover plywood: quick and easy

Grinding. the final stage in many works. And if with ordinary flat surfaces problems arise very rarely, the curved ones require special attention. Choosing the right tool is important here. And this should be done taking into account the peculiarities of the processed object. Grinding nozzles for drills are on sale, but you can make one yourself, using improvised materials for this purpose. It is a lot easier to use a power drill than a handheld tool. His invaluable experience in this direction shared by the author of YouTube channel Alexander Gladyshev.

Curved surfaces can have a variety of different, sometimes very intricate shapes. If you want a perfectly straight result, your grinding tool needs to be the right size and should be easy to work with and easy to change abrasives. For example, to bend a countertop, it is best to use a sanding drum of such height that it completely overlaps the work surface.

It must be said that the diameter of the drum is also important. A tool that is too narrow can be a hassle, and one that is too wide can be difficult to control. There is no need to do any mathematical calculations to calculate the diameter of the drum, such a task can be solved, as they say, by eye.

Tools and equipment

The circles have different stiffness, and are divided into several types:

  • Hard. used when repairing scratches and small chips on parts.
  • Soft and medium. used for grinding and polishing.
  • Relief. used when you want to achieve gloss over a large area.

At the service station are used 2-3 types of circles at restoration of the coating of cars.

  • Body cleaner.
  • Scratch cleaner.
  • Abrasive polish.
  • The fine abrasive composition.
  • Felt wheel with Velcro.
  • Sponge.
  • Soft lambskin wheels.

The polishing machine is best suited to work on the surface. Sometimes a drill with a speed selector and an angle grinder are used.

  • Circular. Externally similar to an angle grinder, the torque is high, the speed is low, so they are rarely used for car finishing.
  • With eccentric. Performs reciprocating motion with a change of position to 2-5 mm. A safe device gives good results, the coating does not overheat during processing.
  • Class of equipment professional or amateur determines price and performance.
  • Power. Equipment with a low index quickly overheats, pauses are made during the work. Weak appliances. 400 to 800 watts.
  • Weight. Professional devices are heavy, lightweight ones can do more work.
  • The width of the disc affects the speed of service. Available in diameters: 125 mm, 150 mm, 180 mm, 240 mm.

Selecting accessories

The master must take care of comfort in the work. for this you need to buy some accessories, if they were not included with the grinder.

To prevent dust from sanding from spreading around the box, not flying on your hands and clothes and not deposited on the work surface, you need several accessories.

First, a dust extraction pipe. Very often it is sold together with the grinder. If not. buy it separately, so it is possible to connect the tool to a vacuum cleaner hose.

Second, a dust canister or a construction vacuum cleaner, which will accumulate dust and shavings. After work, it is convenient to throw excess garbage in the trash can, and cleaning is practically not required.

Third, protective pads. They are not necessary, but they are desirable because they protect the sole of the grinder against abrasion.

Fourthly, replaceable Velcro strips. they are attached to the tool’s platform to replace the old Velcro that holds the accessories.

What to make dummy bits for the special bit

What’s required for a recess grinder attachment on a drill? First, of course ─ so that it can be securely fastened in the head of the drill or screwdriver. The second is that it has the shape and size required for grinding dishes of different diameters.

You will need different sized dummy tips for your work, so you will probably need to use all available materials

Grinding cylinders for an engraver

For this nozzle will need a thin, but strong cloth, glue, a tube of diameter as the nozzle on the engraver and sandpaper.

To begin with, wrap a few pieces of fabric in several layers of 12 millimeters wide on the tube and soak it with glue.

Attention, do not use the wooden tubes and superglue for gluing. Superglue glues the cloth and the tube too strongly, and it will be difficult to tear it off, and do not glue the cloth even with ordinary glue on a wooden tube, because the glue will soak into the tube and glue the cloth with the tube itself, and that will make it difficult to tear them off again.

Cut strips of sandpaper, shaped like a parallelogram and with the same width of 12 millimeters, the length should be such that the strip would encircle the entire tube.

Next, wrap these strips around the dried up cloth, then soak the glue again and let stand.

Carefully remove from the tube, put it on the prepared engraver bit and you are ready to test.

By experimenting with tube diameters, you can make cylinders of different sizes for different needs.

Homemade sanding cylinders are ready.

The drill is a versatile tool that is easy to use for grinding, polishing and surface cleaning. For this, it is enough to buy special nozzles.

The advantages of grinding attachments include the ability to save on the purchase of extra equipment and ease of use. Their disadvantages are lower speed and lower performance compared with professional tools.

Nozzles are divided into several types: cup, platter, drum and others. Each type is suitable for certain works, for example, hard plate nozzles cope well with the preliminary processing of wood, softer. with the final.

You can work with nozzles in two ways: to drive the disk on the surface or to clamp the drill and bring the object to it. The first method is best for large surfaces, the second for small parts.

Polishing tool

As in the previous case, we will need a screw, washers and a nut, only instead of sandpaper will be used felt. After marking a piece of felt, cut out circles of the same radius.

Holes are made in the center of the blanks, they are threaded onto a screw, and then clamped with a nut. The finished fixture is inserted into the chuck of the drill.

One felt will not polish the part, so by turning on the drill, the nozzle is rubbed with Goya paste. After that, you can get to work.

An old and rusty wrench was used for the purity of the experiment. As can be seen in the photo, after a short period of polishing, the treated area was effectively cleaned in a short period of time.

Such a polishing nozzle can work with both flat and shaped parts, but it will not cope even with small depressions.

Leather wheel

As in the above described fixture, instead of felt leather can be fixed, resulting in a fixture for dressing wood chisels.

Use a file

You can use a circular file as an attachment by removing its handle, and clamping the shank in the chuck. A small-diameter file is best secured to the base.

With such a device is convenient to grind holes and semicircular hollows.

Epilogue Regardless of whether you use a purchased drill bit or make one yourself, it can prove invaluable for many jobs.

The main purpose of the drill when working with wood is to drill holes. However, this tool is much more functional than many people think. To expand its functionality use special nozzles for wood, which, in fact, is devoted to this article.

Next we will consider what there are nozzles on the drill for woodworking, and for what purposes they are used.

The most popular brands

In today’s markets there is a wide range of accessories for wood engravers. Due to this fact it is possible to choose namely those tools which will correspond to financial possibilities and necessary needs in a concrete case.

If we talk about equipment of professional level, among the most popular and popular brands are “Dexter” and “Dremel”. These companies’ products can be effectively used for processing metal, wood, glass, and other materials.

As a budget brand it is worth paying attention to the company “Zubr”, offering for a relatively small amount to buy a set that includes up to 180 units of all kinds of nozzles with different shapes, sizes and design features. Such sets are equipped with tools for drilling holes, milling, diamond and abrasive nozzles, cutting discs.

As for equipment from Chinese manufacturers, there is a very mixed opinion about them. Although they cost several times less than high-quality tools, however, such tools can’t boast of their reliability.

over, as part of Chinese kits contain far fewer components than branded versions. However, professionals will be able to cope with such equipment in principle. True, you will have to change tools often.

Making nozzles with our own hands

To perform simple engraving works at home, the necessary tools can be made from improvised materials.

For example, the simplest cutter is made from a fluted wheel from a lighter or a dowel, which has previously drilled working teeth.

To make a sanding nozzle will be enough to use a wooden drum, equipped with a shank with sandpaper glued to its side.

Most of the attachments created with your own hands do a pretty good job. Costs are kept to a minimum.

Which equipment option to choose depends entirely on the requirements and capabilities of the craftsman, whether the tool is Chinese-made, homemade, or a professional appliance.
