What advantages does a homemade tool give us? In addition to significant savings, there are other advantages: multifunctional structures take up less space, can be disassembled and easily adapt to your specific needs. For example, a wood sander is a rather bulky tool that needs a separate place to place it. But if you assemble it from an ordinary drill and a couple of plywood stands, then all this can fit very compactly on your workbench. Moreover, the devices for such a machine for the most part can be made by hand. How to implement this in practice, the author of the channel told in his video blog on YouTube Mazay DIY. You can easily repeat his experience by studying these step-by-step recommendations.

Machine base - drill stand
So, the basis of the machine is a mechanism that will rotate the grinding attachments. It is difficult to imagine anything more convenient for this purpose than a conventional drill. There are only two transformations that need to be done: decide how to fix the instrument and how to turn it on, freeing your hands.
You can solve the issue of turning on the drill using a special device with a pedal. It is only necessary to fix the button of the drill in the on position and put a pedal between the power source and the plug of the drill, which supplies and disconnects the current. These pedals can be found easily at tool stores or online.
The second question, fixing a hand tool, is also easy to solve by building a wooden stand.

Grinding wheel stand
For sanding small, complex parts, a sanding disc is useful. The only thing that is inconvenient in this situation is to keep the parts suspended during operation. This is easy to fix.

Platform dimensions - 12 by 15 cmPHOTO: YouTube.comA second platform of the same type is attached from the reverse side. In it you need to make two holes in the center to fix the guides.PHOTO: YouTube.comThese two bolts, movable between the wooden "rails", act as guides. All nozzles are attached to them using a pair of wing nutsPHOTO: YouTube.comNow the stand only needs to be installed and secured to the grinding wheelPHOTO: YouTube.comWith such a comfortable palm rest and parts, you can work with small objects
Grinding drum for a homemade machine
In addition to the wheel for processing parts, you really need a drum. Making it is also easy.

The feet should now be slightly higher than the drill head.PHOTO: YouTube.comTo make a drum, you will need to prepare several wooden parts using a special circular drilling attachment.PHOTO: YouTube.comOn the two parts that will be on the edges of the drum, you need to make a straight cut. This saw is useful for fixing sanding paper.PHOTO: YouTube.comPlace all the wooden circles on a metal stud and glue them together with wood glue. Place the sawn-off parts along the edges of the drum and pull them off the edges with a pair of washers and nutsPHOTO: YouTube.comYou will need to get rid of the excess threads on the stud so that nothing interferes with the rotation of the drum. Remove it by fixing the pin in the drill chuck, rotating and rubbing with a sharpening stone or a block with fixed emery.PHOTO: YouTube.comTo install the drum in the legs of the "shelf" you need to drill holes for the bearingsPHOTO: YouTube.comTo change the angle for feeding parts during sanding, you need to attach a plywood platform to the shelf. Use a piano loop for this purpose.PHOTO: YouTube.comThis movable platform should have legs - this is a pair of bars approximately 6-8 cm highPHOTO: YouTube.comInstall the platform and insert the pin into the drill chuck. The drum itself is still uneven, so the first thing you should sand on such a device is the surface of the drumPHOTO: YouTube.comTo fix the sandpaper tape, first put its edge into the slot on the drum, screw it with a small self-tapping screw, and then wrap the drum in a spiral and repeat the procedure at the other endPHOTO: YouTube.comIt is very convenient to work on such a device: the plywood platform will allow you to feed the parts evenlyPHOTO: YouTube.comThe tilt angle of the platform can be adjusted using the bolts in the legs from the bar
So, using only wooden and plywood parts plus an ordinary drill, you can assemble a fairly productive and convenient woodworking machine. The whole structure, if necessary, is easily disassembled; parts can simply be stored on a shelf in a garage or workshop.
In addition, here is another option for assembling a grinding drum from the masters of YouTube:
